History part 2 of the HNSKY planetarium program.




2016-8-2,  Update in deepsky databases. Improved several minor things including Rosetta nebula.

2016-8-1,  Minor corrections in version HNSKY 3.2.2g.  Added new supplement with official IAU star names, version 20-7-2016, source  https://www.iau.org/science/scientific_bodies/working_groups/280/ 

2016-7-20, 3.318a Linux version, changed constellation Bayer letters to unicode.

2016-7-15  Updated the program ORB_DEB, executables for win32 and win64 and Linux!. Simple windows program which calculates the orbital elements of a minor planet based on three observations/positions using the Gauss method: Download ORB_DET.ZIP version 1.02.  

2016-7-13,  HyperLeda_2.440.000_galaxies database (type hnd) Dated 2016-7-135 (26 MB) Unpacked is this file 103 mbytes, so huge.  Place this huge deepsky database in the HNSKY PROGRAM directory. You have to select either this one or one of the three deepsky databases.

2016-7-12, Very minor update in the MS-Windows version v3.2.2.f. Adaption is font size handeling for Calibre, Night vision menu check mark was working.

2016-5-14 version 3.2.2.d Added an image on/off button to the object menu. Fixed color change option of main menu in menu color settings

2016-4-27 version 3.2.2.c Fixed an exception error only occuring under Wine (Linux). Better adaption of the stars density to the window size. 

Printing. The printing routine will rebuild and adapt the screen view to the printer resolution.  Laser printers will produce sharp and good quality prints. The size of the window and monitor resolution are irrelevant.  From version 3.2.2b the size of the printed stars is no longer adapted to the DPI resolution of the printer.  A low resolution of  of 72 or 144 DPI will give the correct star size (a few pixels) for printing on paper.  If you select 1200 DPI you will get much smaller stars (still a few pixels), more intended for zoomable digital maps. You could use this for printing to PDF

2016-4-19, Removed twelve Sharpless2 duplications in deep sky database.

2016-4-18, small update of the help file, added describtion of the deep sky observations file.

2016-4-17, version 3.2.2b, small update in printing routine. 

2016-3-28, update for the Catalan and Esperanto module added. Webpage cleanup. Release specialised tool:  SKY_TOASTER, program for conversion to the TOAST projection,with Delphi source.  v0.0

2016-3-20, update for the Spanish module added.

2016-3-13,version 3.2.2a. Added missing Milky Way toast projection to the installer.

2016-3-11,version 3.2.2a. Improved azimuth in degrees indication.

2016-3-10,version 3.2.2a 

- Milky way panorama based on an ESO full sky panorama.It is slow, so use it optionally.
- Introduced galactic coordinates.
- Added 150 Sharpless-2 objects to deepsky database 3
- Auto size filter in object menu.
- Filter function now also works for supplements
- Added the unicode planet symbols  "☿♀♁♂♃♄♅♆♇", sun "☉", moon "☾", comets "☄" to new language files english_symbolic_win10.ini  and english_symbolic_win7.ini. Win10 allows some more unicode symbol like the floppy symbol "💾"
- Better protection against bad FITS files.
- Many small improvements.

Notes:

1) All non-english.ini language files are now converted to unicode encoding (UTF-8) rather then ANSI encoding. If your native speaker of one of the languages, please check if they display properly.

2) The Milky Way in a "TOAST" projection is stored in a single PNG image and kept in memory for speed. It is made from the ESO0932a full sky panorama in equirectangular projection. This panorama had some distortion up to one degree, but I managed to warp it such that it match pretty well. The specialist tool (sky_toaster) for making a TOAST projection including code will be released to public domain the next days.

Milky Way panorama in HNSKY program


2016-2-14, Version 3.2.1a, improved protection against bad FITS files.

2013-9-3  Release of version 2.4.0a  Small cosmetic correction for UCAC4 catalog at poles.

2013-6-12  Release of version 2.4.0

2013-5-28  Release of version 2.4.015 Complete installation package. Language files adapted  to  version 2.4.0

I hope to issue HNSKY version 2.4.0 within one or two weeks. Today I prepared a complete package with installer, based on version 2.4.015. It is 54 mbytes large.

All the language files are adapted with English additions. If one of these files is in your native language, please feel free to update the language file. See remarks at the end of this email. If you find anything wrong or you have a small request, please report so it can be included in the final version 2.4.0.

All FITS files have been renewed and are mainly based on DSS2. I did some manual tweaking and some FITS are effectively removed by giving them a size of 0 bytes. The power of HNSKY to size and place a DSS image anywhere was a great help. Note that default SKYVIEW downloads are set to DSS2 red, ESO download at DSS1 and MASTdownloads at DSS2. Skyview is your best option for wide fields.

For the record the following has changed:

1) Downloading DSS images via internet is more integrated. Just hit one of the DSS servers in the popup menu and after a few second the DSS image will be shown in HNSKY. HNSKY will store up to 9 images in the FITS directory as download1.fits, download2.fits.... After 9 files it overrides the first to prevent creating too many files. The size of the DSS can be defined by the rubber square.

2) Secondly in this version the comet or asteroid database can be updated with a button click from the settings menu. The update is then downloaded from www.minorplanetcenter.net. Furthermore the editor can read and convert "mpcorb.dat" and "astorb.dat" asteroid files. Asteroid have now a size based on the absolute magnitude and standard albedo (0.15). Conversion of 30.000 object takes 5 minutes or so. Note that the complete database of 353.000 named objects will take hours!! . So first reduce "Mpcorb.dat" in a tekst editor below 10 mbytes or. You can read any *.dat file but it will assume "mpcorb.dat" unless the filename is "astorb.dat" or "AsteroidElements.dat" from Occult.

3) Introduced a mouse popup menu. Note that you can also pull a rubber square with the right mouse button to size a DSS download or define a Simbad area search.

4) Numerical integration for asteroids to achieve highest accuracy positions years in the future or past. Select in editor a number of lines and push right mouse button to select numerical integration. The error is less then 1" after 10 years !!! So a asteroid file from 10 years ago will after numerical integration be within 1" accurate!!

5) Small changes such as reverse mouse wheel action, time stamp markers, improved drawing lines, online request to Simbad and other sites. Also plotting FITS at wide fields is now possible. See settings menu option "show early"

For translaters have a look took  section  [popup] and

2013-5-20  Release of version 2.4.014 Clear markers reinstated in popup menu. Faster FITS plotting for small projections

2013-5-15  Release of version 2.4.013 Lock RA/DEC back to orginal, no erros message on empthy fits directory.

2013-5-13  Release of version 2.4.012 Fixed cntrl-Z, double click mouse, middle mouse botton and alt-right mouse centres on object. Line mode alt-az fix.

2013-5-12  Release of version 2.4.011 Fixed UCAC4 search, modification popup menu for Windows simulators under Linux.

2013-5-3  Release of version 2.4.010 UCAC4 name standardized with '-'

2013-5-3  Release of version 2.4.09 Font style adjustable such as no underline

2013-4-7  Release of version 2.4.07 Bug fix statusbar message and limit minimum DSS size. Added asteroid and comefile update to pull down menu.

2013-3-31  Release of version 2.4.06 Bug fix DDE  and ASCOM.

2013-3-29  Release of version 2.4.04. Note that you can pull a rubber square with the right mouse button to size DSS download or size area Simbad search.

2013-3-9  Release of version 2.4.01. Introduced mouse pop menu, Numerical integration for asteroids to achieve  accurate positions years in the future or past. Select in editor a number of lines and puch right mouse button to select numerical integration. Small changes such as reverse mouse wheel action, time stamp markers, improved drawing lines, online request to Simbad and other sites.

2013-3-2  Release of update version 2.3.25. Added astorb.dat import

2013-3-2  Release of update version 2.3.24. Asteroid have now a size based on the absolute magnitude and standard albedo (0.15). Furthermore it can import and convert minorplanet "Mpcorb.dat" in the editor. Conversion of 30.000 object takes 5 minutes or so. Complete database of 600.000 objects will take hours. How bigger the slower since it is inserting replacing all the time. So first reduce "Mpcorb.dat" in a tekst editor below 10 mbytes or. If you try to read a *.dat file, it will assume Mpcorb.dat. It can also read AsteroidElements.dat from Occult. 

2013-3-1  Release of update version 2.3.23. In this test version, downloading DSS images via internet is more integrated. Just push the DSS button and after a few second the DSS image will pop in HNSKY. HNSKY will store up to 9 images in the FITS directory as download1.fits, download2.fits.... After 9 files it overrides the first to prevent creating too many files. the comet or asteroid database can be updated with a button click in the settings menu. Update i then downloaded from www.minorplanetcenter.net. Furthermore the editor can read and convert Occult asteroid files.

2013-2-25  Release of update version 2.3.21. In this test version, downloading DSS images via internet is more integrated. Just push the DSS button and after a few second the DSS image will pop in HNSKY. HNSKY will store up to 9 images in the FITS directory as download1.fits, download2.fits.... After 9 files it overrides the first to prevent creating too many files. Much better then in the old version where the browser is called as I build in 2003 or so. Those days I didn't even had broadband.

In menu SETTINGS you select  the  link. The "skyview" link works up to 10 degrees since is can increase the pixel size. This works better then the ESO link The ESO link is limited to one degrees. After one degrees tthe FITS become too large to handle and at two degrees ESO can't made FITS images anymore. The FITS image is default requested as 1/3 of the screen size.

The differences occured in the 1-byte fields (items 4,5,7,14-17,22,23) which are meant to contain signed integers with an offset of 127.

2006-3-11    ini_ga.zip (11 Kbytes) Galician language module by Xoaqun Freixeiro.

NOW large basic package is available:

2005-9-25  Large basic package HNSKY230_large.EXE (40 mbytes v2.3.0i) complete with small SAO , large TYCHO2 star database, deep sky help file, non-English menus, planetary and 255 deep sky images.

2004-6-20   HNSKY version 2.3.0c complete or alternatively download  update 2.3.0c  minor corrections in locking routine.

With version 2.3.0 unintended the large 10.000 asteroid file was added. In some cases it makes the program a little slow. Version 2.3.0c contains only the smaller 2004 bright asteroid version. It is up to the user which version he/she wants to use. Alternatively you could reduce size of the large one. The larger is always available at http://www.hnsky.org/hns_ast1.zip or download the latest data from the minor planet centre as indicated in the asteroid file and convert it with the tools found at my webpage http://www.hnsky.org/software.htm

Please report any problem or ideas for improvement. I can't promise to implement them all, since I will move house and country very soon, but they have been and still are a great help.

2004-6-19 Version 2.3.0b, improved the locking routine. Now it will lock on any solar object (including asteroids and comets) after a mouse click and stay locked even after using the arrow keys. When locked use small time steps of 1 minute or 1 hour only. Fixed a problem finding low numbered UCAC2 stars in zone Z001.

2004-6-13 Version 2.3.0a, fixed a problem saving setting "FITS=on". Secondly the use of the search window doesn't cause any longer a screen repaint.

2004-6-5   HNSKY version 2.3.0 complete or alternatively download update 2.3.0

HNSKY or the Hallo Northern Sky planetarium program is now at version 2.3.0. The last newsletter was send November last year. Since then there have been many small changes which took a long time to implement. The SETTINGS and OBJECT menu have been modified a lot and with the new internet access, DSS images can be downloaded with a tool button. Your internet explorer will be instructed to get them from the internet but you have to save them manually in your FITS directory. After a refresh (spacebar) the DSS/FITS image will be displayed in your HNSKY map. Another change is that language modules are now in one new *.ini file.

The most conspicuous change is that interface of the SETTINGS menu has now an Earth map for quick setting your location and in the OBJECT menu all available databases are shown with there new long file name.

It is possible to  download the basic package and install it in your existing HNSKY directory. However I suggest removing old files there as described next or use the following http://www.hnsky.org/remove.zip  MSDOS Batch file to do it (but make a backup of your local horizon and self made supplements). Manual instruction:

1) Remove the old deep sky databases HNS_SAC1.DAT, HNS_SAC2.DAT, HNS_SAC3.DAT since they are now longer used. The new renamed ones with long file names and the *.HND extension will be installed with the basic package.

2) Secondly put away all your supplements with the *.SUP extension (but make a backup of your local horizon and self made supplements) since I have given them all new long file names and you probably don't want them double. Several are added to the basic package .

3) If you have a non-english language module, remove all ten HNS_*.TXT files and download the new single file language module from my webpage.


- Deepsky databases have for version 2.3.0 a new file extension *.hnd. In the update deep sky level 3 is not included. Rename your old hns_sac3.dat to "Deepsky level 3.hnd".

- fixed find/replace problem in editor

- Fixed a problem displaying not enough UCAC2 stars on the left side caused by some forgotten test code. Now the screen is symmetrical filled with UCAC2 stars.

- Image below indicates how to blank the new combo boxes.  This is also valid for the supplements in the OBJECT menu.

-  Highest position of objects is now indicated as a hint when you move your mouse to the Rise/set info.

- Major update in settings menu and object menu.

- Single file for non-english language modules.

- Added "load FITS file" menu in FILE  menu. With this menu option you can identify not well named FITS image files.

- Added several monochrome images to the Hnsky help file. Monochrome images keep size very small.

- Introduced a location menu for first time users.

- If no settings file "default.hns" is found, HNSKY will take the timezone and daylight savings from Windows settings.

- Romanian HELP file translation by Haritina Mogosanu.

The map is monochrome to keep it very compact

- Allows both access to ESO and Skyview DSS server.  Skyview allows any pixel resolution and is good for wide views.  See new Tabsheet in settings.

- internet hyper link to the ESO DSS image server. It is implemented as a new tool button and will start your internet browser with the the required link. You have to be online in the internet. Save the download as a FITS file to your HNSKY FITS directory. After a repaint, the FITS image will be shown.  The size is 1/5 of the screen size. Zoom in to keep them small. Please report any problem.

- Faster FITS image routine and improved in  keyboard routine.

- Danish  constellation supplement.

2004-3-10   HNSKY version 2.2.2j update or complete basic package 2.2.2.j Very small update night vision for Windows XP classic colors. Nightvision does not work for standard XP color schema. Updated Large asteroid file containing 10000 asteroids/minor planets (Version March 2004)

2003-10-23 Final version basic package HNSKY 2.2.2  (2 Mbytes) or update HNSKY version 2.2.2 (500 kbytes)

- Comet and asteroid label colors adjustable.

- Improved FITS routine including new colored deep sky fits images. If you place them in the your existing FITS directory, Remove manually your old monochrome M16, M20 and NGC2360 files. The last is identical to M16. The images are from Chris Deforeit homepage Wonderful good ! His images are copyrighted but "Non profit use welcome if credit given."

- Support for the new UCAC2  support see screenshots UCAC2

- New boldness routine for the GSC, USNO-A and UCAC2. It looks more natural however the boldness factor jumps if these catalogs are selected. So instead of reducing the contrast, the boldness is increased. The magnitude differences between the stars is now more easier recognised.

- Moon_map (B&W 1000x500 pixels) and medium maps of Jupiter and the Jovian satellites, Saturn, Uranus, Neptune and  a large Mars map (Color 1000x500 pixels) and large Jupiter map (Color 600x300 pixels) . The planetary FITS files should be placed in your FITS directory. The FITS directory can be set in the menu SETTINGS, shortcut CNTRL-E  (The Moon map is now renamed to MAP_MOON.FIT so you could rename your old one. The new Mars map MAP_MARS.FIT is a COLORed version. Reports are welcome. Activate the FITS images (cntrl-F) to see Moon/Mars.

Conversion of maps was done with new HNS_FITS version 1.4.0 which can now produce RGB color fits. Maps are modified JPL/Nasa compilations from: James Hastings-Trew.  . See also http://maps.jpl.nasa.gov/

The optical libration of the Moon is included. The rotation of Jupiter's is based on red spot rotation info from Bill Gray's Web page about Great Red Spot transit times.  The mathematics are simple linear functions of time but a lot of vector based rotations in several x,y,z planes are required (one day I will maybe will write something about that). The orientation of planetary axis and rotational elements of satellites can be found in the following  IAU-IAG report

2003-6-17   HNSKY v2.2.17d  Sync command for the ASCOM telescope driver.  Mouse pull square box possible without using shift or cntrl.

2003-5-11   HNSKY v2.2.16  There have been two major changes in the version 2.2.16:

1) If you are using a non-english version, use the attached upgrade.exe program to update since several labels in the non-English modules have been modified.

2) The shortcut labels in hns_Lmai.txt have been all changed to adapt them to the other labels in use. You have to update your personal settings completly using the attached hns_Lmai.txt file !

2003-5-5   HNSKY v2.2.13  The new keyboard routine was more difficult to program then expected. Only with current version 3 , I'more or less satisfied with the keyboard responses for the function and page up/down keys. The problem is that  I have to work around the standard key routine inside the pulldown menu.

2003-4-25   HNSKY v2.2.0k3  and HNS_REAL 1.0.3c. More adaption for the FITS format.  HNSKY accepts now the FITS files with a WCS header containing the new conversion matrix ( keywords CD1_1, CD1_2, CD2_1, CD2_2 instead of  CDELT1,2 and CROTA2 keywords). HNSKY will now work with FITS files from  http://cadcwww.dao.nrc.ca/cadcbin/getdss You can now use the batch routine of this provider to get FITS files.

2003-4-18   HNSKY v2.2.0j  Adapted for SBIG and Skyview 32 bits (-32) floating point FITS file format. Also HNS_REAL and HNS_FITS adapted for SBIG FITS files.

2003-3-2   HNSKY v2.2.0h  New deep sky level 3 database HNS_SAC3.DAT !! Corrected position for several faint IC objects.  For HNSKY additional correction in the automatic suppression faint deep sky names. The help file is updated in the basic package hnsky220.exe version h

2003-2-23   HNSKY v2.2.0g  Automatically suppresses faint deep sky at wide field views. 

2003-2-8   HNSKY v2.2.0f  Fixed a missing repaint after changing AZ/Alt  to  RA/DEC grid is selected. Upgraded HNSKY, HNS_FITS and HNS_REAL for signed 16 bit FITS instead of un-signed 16 bit FITS. Not relevant for 99.5 % of the users.

2003-2-3  Korean sky map now with constellation names phonetic written in ASCII.

2003-1-25   HNSKY v2.2.0e  Problem with adjusting FONT family fixed. Now it works as in version 2.1.4. If any other problem arises, please report.

HNS_REAL: Small update in the Realsky viewer hns_real.zip version 1.0.2. Allows saving 8 FITS images with current brightness and background settings.

Hint: For Orbital Elements for comet C/2002 X5 (Kudo-Fujikawa) download: http://cfa-www.harvard.edu/iau/Ephemerides/Comets/Soft06Cmt.txt  

For info look to: http://cfa-www.harvard.edu/iau/Ephemerides/Comets/2002X5.html

2002-12-30   HNSKY v2.2.0d  Fixed a small problem with the ASCOM tool bar. It became visible when loading an *.hns file where it was not docked. Secondly Cntrl-R made exclusively for cross hair.

2002-12-28   HNSKY v2.2.0c  Accuracy of rise/set times slightly improved.

2002-12-20  Updated the large asteroid file hns_ast1.zip (0.5 mbytes) with the data of 10000 asteroids for december 2002.

2002-12-11   HNSKY v2.2.0  Final version including december 2002 asteroid and comet file.

2002-11-12:  HNS_FITS version 1.2.1  Improved accuracy in case the image is streched. Added two more info fields and fixed a bug in the import routine for FITS files (resulting in harmless double entries). Several internal improvements.

2002 September, Oktober, November   HNSKY versions  Modified error messages for missing FITS and USNO files. Combined access of the GSC and USNO (SA) is now possible.  Mouse click finds USNO stars. The CCD measuring grid was 10 ,20 % wrong in size. Also the telrad size had to be slightly adjusted and fixed. HNSKY has now an ASCII default.hns file instead binary. Conversion goes automatically. This allows future changes in settings file without loosing you old settings. If required you can also modify the *.hns files yourself manually or by an external program. HNSKY can use the ASCOM  telescope driver directly ! You have to download and install the program from ASCOM too (7.2 mbytes). Secondly, many small internal changes in supplement interpretator. Now magnitude filtering for deep sky and stars works as desired. Found and fixed a position pre-filtering function in the supplement read routine. Large supplements such as Leda should now plot much faster. This bug was there for a long time. Also introduced magnitude filtering for deep sky and stars in supplement. Small correction in the pre-selection of FITS files so the FITS image corners are also visible wenn using high zoom factors. Secondly, smoother display of moon phase curve. Tiny correction in HNS_FITS for saving Fits files. Thirdly, renamed the 255 deep sky FITS files extension from .FIT8 to .FIT. Very small correction in repaint after switching on/off  "found instruments" "pointing circles."  Secondly "deep sky contours only" is switched on automatically if FITS images are enabled.

2002-9-11: For historical and scientific purposes, the complete Bonner, Southern and Cordoba Durchmusterung of the 19 th century in a HNSKY database: durchmus.zip  Size 10 mbytes containing more then 1.000.000 stars.

2002-9-6:  HNS_FITS version 1.1.0 Introduced scroll bars, stretching image  (like zooming) and improved star locking. 2000-9-8 version 1.1.0a b. Small fix for disturbing white bars occurring outside images if previous reference stars where outside range. v1.1.0b, small fix for calculating mouse position in stretched images.

2002-9-4 : 1) hns_real.zip Added batch routine for converting multiple FITS to BMP. 2) Added to the conversion tools hnskypd.zip a program to convert the 19 century Bonner, Southern, Cordoba Durchmusterungen to HNSKY format, equinox 2000.

2002-7-8 :  After searching for a way to implement a Moon map in HNSKY, I found the following MOON MAP  (1000x1000 pixels JPEG file, 550 Kbytes), excellent painting by Don Davis for viewing, printing and so on. One of the best Moon overviews available. I did some experiences with implementing a Moon map in HNSKY but the quality is always lower then a fixed size image, so for the time being I have given up.

2002-7-7 :  Korean language module and help file. See non-engl.htm .

2002-6-26 :  Second set of  hand made drawings as FITS file bringing total at 16 pieces,

2002-6-16:  Oooeps, the LEDA supplement was damaged at my computer !  Now corrected. The original file unpacked should be about 4.4 Mbytes and contain 71357 lines. If not download this one HNS_LEDA.ZIP  (1.5 Mbytes). Updated two hints of the the non-English modules for the new deepsky database.

2002-6-14:  Corrected some open cluster FITS images. See hfits1.zip 

2002-6-13:  Uploaded again HNS_LEDA.ZIP. Also some correction in the new hnsky deepsky  (HNS_SAC1..3.DAT) database. Still corrections for Messier possible. See erratta.htm

2002-6-11: Finally the new version  HNSKY 2.1.4 (950 Kbytes) for the updated deepsky database format. Introduced a new type IV deepsky database HNSKYD4.ZIP containing HNS_SAC1, 2 and 3.DAT database with 25.500 objects instead of the normal 10.000. Also the database format has changed, so this new deepsky database works only with this version 2.1.4. Numerical accuracy is now much better. The database is based on SAC72, Wolfgang Steinicke's REV_IC and Leda. Till magnitude 15.5. GX>=1 arcmin. Old deep sky databases are supported for some time as long "type III" is in the first line. Also introduced a HNS_LEDA.ZIP supplement with 71000 galaxies extraxted from the Leda database.

2002-6-4 : HNS_FITS 1.01a  On some computers/Windows versions a part of the large image was lost. Fixed.

2002-5-31 :  First set of drawings as FITS file, made by Todd Nowlan. (7 pieces.)

2002-5-26 : Added Chinese star supplement. See non-engl.htm

2002-5-9 : HNSKY 2.1.3d  Made the found markers  "telrad" and "object name" resident. So you can print now maps with up to 12 telrads.

2002-5-7 :  New Portuguese and Hungarian language module. Small update in German one. See non-engl.htm . Updated  Milkyway supplement for new supplement standard of 2.1.3. So colours are now again medium and faint deepsky.

2002-5-3 : Fixed a bug in the copy to clipboard function. See HNSKY 2.1.3b  After second copy and paste, a message occured "clipboard not available". Fixed.

Secondly Comet 96P/Machholz 1 caused a floating point error in the year 1960. Error is now ignored and displayed in the status bar when stars are switched off.

2002-5-2 : Introduced German translation of constallation names. See non-engl.htm

2002-4-26 : Small improvement in the  lx200.exe program (Version 1.00b ). Added the # sign in the beginning of the instructions to the LX200, which should solve problems some users have. Updated the German language module. You will need HNSKY 2.1.3a since one text window was longer then foreseen.

2002-4-22 : Small correction in hns_real.zip Resizing FITS windows after sampling change works now better.

2002-4-17 : Update most non-English modules with two additions.

2002-4-15 : Release HNSKY 2.1.3  Fixed a major accuracy problem with eclipses. Accuracy should be better now. Added the possibility to add an "user-defined-horizon". See attached supplement example hns_hori.sup. More flexibility in color selection. Now you can set the colors of inner, outer planets and moons different then stars. Introduced azimuth grid lines and modified the minimum size of planets for wide field views  to get same impression as bright stars.

Added a short article about averted vision in the hns_deep.zip v3.2.1 file.

The LX200 program version 1.0 is re-issued instead of version 1.1. As soon my LX200 is again back, more testing will be done.

Languages modules should be upgraded by downloading the latest versions, type 2131.

2002-3-23 : HNS_FITS 1.0b  Fixed a bug resulting in a major error when using small fonts in Windows 95 98.

2002-3-4 : HNSKY 2.1.2b Improved night vision colors for the two FITS trackbars. I missed it while my telescope is already 7 months away for repair.  Secondly hns_fits.zip, corrected an DEC sign problem for stars with a negative declination.

2002-3-3 : Updated the HNSKY.HLP file for the new features. 1) Projection method, 2) Saving and loading program status, and new 3) Non-English, The help source hnsky.tpc file is available at www.hnsky/hnsky_h.zip

2002-3-1 :   HNSKY 2.1.2  New version with the "AZIMUTHAL EQUIDISTANT PROJECTION" method. Hope you like it. I had to modify a lot in the very heart of the program to  make this happen. So it is possible I have missed something, so please report any abnormalities. Download the latest language module if your using a non-English version. 

2002-2-23 :   Recompiled  version 2.1.1 so the hint of the font button is now on. Uploaded Romanian module.

2002-2-16 :  HNSKY Final version 2.1.1 with seperate Italian, Spanish,  Russian, German and Czech versions. See non-engl.htm

2002-2-14 : Supplement Bright quasars and BL Lacertae objects  compiled of list from Wolfgang Steinicke webpage (02-2-14) by Graham Furstenberg

2002-2-11 : HNSKY v 2.1.0.o. Version 15, new color routine for displaying FITS. Now white FITS on blue background possible. Based on a idea (Alpha blending) of Leandro Rios.

2002-2-5 : Small change HNSKY v 2.1.0k. Fixed rise time of the moon if close to 23:59 hours.

2002-1-26 : HNS_DEEP.HLP 3.2.0. Added latest files of Steve Gottlieb for NGC5500 till NGC6500. 200 Kbytes more object info.. Update in , Italian, Spanish, Catalan,  Russian, German and Czech versions. See non-engl.htm

2002-1-13 :

- HNS_REAL  Final version 1.0.0. Added info "bandpass" and fixed a program crash problem.

- HNSKY 2.1.0f Improvement for repaint of the screen for FITS images. Small correction for hotkeys N,S,E, W with respect the North-up option.

2001-12-28 :   Added fits supplement containing large and small magellanic cloud. Also updated the size and orientation of the large megellanic cloud (LMC) in the deepsky  databases

2001-12-22 :Important: For HNSKY 2.1.0a or later, download the version II (5 mbytes) of the deepsky FITS files. (FITS files created 2002-12-22). Otherwise they will be about on image pixel shifted. There was a double but partly compensating error in the first versions. About one pixel in the FITS files and one pixel in HNSKY. The Fits files had 0.5 pixel shift to the WEST and 1 pixel to the North. HNSKY had 1 to the East and 1 to the South so total effext was only 0.5 pixel.

- HNSKY v2.1.0 b Added re-draw function by space-bar.

-  Version II of 253 deepsky FITS images  (5 mbytes)  Indentical as I, except for one pixel shift to the North and  0.5 pixel West correction. Use this version for HNSKY v2.10.a or later.

2001-12-19 :

- New program HNS_FITS to convert BMP files to FITS files with a WCS header. The right size and orientation is determined by entering two star positions. So now you can blend you own picture inside the map of HNSKY. See example files added.

- HNSKY v2.1.0 A very very small correction (one pixel) in the display of  the FITS files in HNSKY.

There is still 1 x0.5 pixel shift bug in the sub smapled FITS files produced by GET_DSS of HNS_REAL and therefore also in the FITS files provided.  

2001-12-11 : Final release of HNSKY version 2.1.0  Also added the possiblity to change to grid step.

2001-12-7 : 253 Deepsky images mainly from Realsky for use with HNSKY. A total 5 Mbyte  Delete your old FITS files !!

2001-12-4 : Almost final  HNS_REAL  v0.999 and HNSKY v 2.099 Check your brigthness/background settings in this version when you use your old default.hns

2001-11-17 :  HNSKY v 2.098 and HNS_REAL  v0.995 These two you have to download to be able to view pictures from  Skyview.gsfc.nasa.gov . This server produces 32 bit floating point FITS with adjustable resolution and size. First load the downloaded FITS pictures in HNS_REAL and then save them to 8 bit integer FITS. In the following package some nice high resolution example pictures of M8, M20 (0.3x0.3 degrees), M31 (2x2 degrees) and M42 (2x2 degrees) are included.:   Messier objects from Realsky North a total 1600 Kbytes, subsample 5 equals 8.5 arcsec/pixel plus 4 high resolution pictures from skyview.  The skyview converted pictures only work with Hnsky 2.098

2001-11-07 : HNSKY v 2.095  and all messier objects  Improved wild cards selection for FITS files. FITS sizing is now correct for files from:

1)  http://archive.eso.org/dss/dss 

2)  http://ledas-www.star.le.ac.uk/DSSimage This one allows subsampling and can therefore  produce small overview files of 90x90arcminutes. Select  pixel size a factor large then 1.7 arcsec/pixel. So 1.7 or 3.4 or... 17 arcsec/pixel.

Other DSS servers will not work. See below:

To get it running do not forget:

1) Set "Path to FITS files" in menu settings (cntrl-E)

2) Enable FITS in main menu "SCREEN"

I'm currently struggling with the two FITS format. There are many different FITS headers. HNSKY uses the WCS factors to decode the image. I have looked to all DSS servers and only the ESO server provide FITS file which can be read by HNSKY. Others do not provide a WCS plate solution or the RA/DEC position is missing.The standard DSS FITS header has 20 x,y polynom factors such such as AMDX1, AMDX2. I never read a FITS manual but by what they call backwards engineering,  I did found out how the decode the additional WCS headers. They are also much easier to decode. The DSS file produced with HNS_REAL has the the DSS FITS header plus the WCS (or also called IRAS which is a subset). At this moment only the ESO server produces DSS files with this addittional newer WCS header for encoding. One or two others do the same but do not provide a pixel reference or RA/DEC reference. That's why HNSKY can only read DSS FITS files from HNS_REAL and the ESO. Anyhow at this moment I will leave it as it is since the WCS is the new standard and used for many other surveys such as Sloan .

For cases that HNSKY becomes too slow due too many FITS files (100 files is no problem) wild cards such M_6*NGC4*.fit* could be used.

So to get FITS files inserted you can use :

1) HNS_REAL program to extract them from the DSS/Realsky. Here you can subsample them

2) You can download them from the ESO. Unfortunally only 1.7 arc/pixel. So large.

3) Download them from my webpage. See: software.htm

These files contains keywords such as CROTA2, CDELT1, CDELT2 and the position of the reference pixel. If anybody can or has a conversion FITS program to convert the other FITS files, please inform me !! Also detailed info regarding DSS polynom decoding is welcome. I have search ed through internet but this is complicated.

2001-11-05 : Experimental HNSKY v2.093. This version blend-in all available *.FIT FITS pictures. About ten *.fit pictures added to above file. This time I could test this version with a laser printer here. After some tricky try-outs ,it is now printing here correctly .

Tip: You can also download your own FITs pictures from the DSS online such as http://archive.eso.org/dss/dss and just put them in your HNSKY directory. HNSKY will examine any FIT or FITS and blend in if required.

How this all happened: Initially I worked several weeks on my new Realsky viewer. The initial idea was to keep this viewer as a separate tool for the lucky guys who owned the Realsky or DSS survey. Then two days ago, Bill Anderson told me enthusiastically about new little pictures in Guide 8. This kept me thinking of something simular. I have been always most impressed the way Guide 7 handles several Realsky or DSS pictures. I haven't seen these new Guide 8 little pictures, but just as an experiment, I spend a few hours try to merge my HNS_REAL FITS routines in HNSKY and yes.......very nice pictures suddely showed up in my mionitor.

So now you can have of each deepsky a small or large picture with the right size and orientation. In principle it was very simple. Every DSS/Realsky FITS file contains the corner positions, size and orientation. So with some tricky mathematics ,it is possible to calculate the RA/DEC position of each pixel in the Realsky picture and plotting it inside of HNSKY was pretty easy. So in future, you can expect a Messier or even bigger package of small FITS pictures which will nicely blend in HNSKY.

Please send in your comments

2001-11-02 : HNSKY  v.2.085 Fixed some nasty problems and added a new DDE item "center".  If you have v 2.085 dated 2001-11-1 please download this version 2001-11-2.

First when the DDE import was on, the program could not start in the Horizon mode. Fixed a problem with the DDE controlled  telescope cross. Fixed a problem that DDE import/export was not on, after HNSKY was started from HNS_REAL. So this could solve the DDE problems of some users. And finally added a new DDE item called CENTER to control the center of the screen instead of the DDE telescope cross. See HNSKY.XLS example in DDE examples hnskypi.zip

2001-10-27 : RC3 galaxy supplement or Third Reference Catalogue of Bright Galaxies. Contains 23011 galaxies. HNSKY v2.084a, very small update.

This viewer can be DDE controlled from the HNSKY program and objects can be centered by clicking on them with the right mouse button. Secondly there position can be send back by DDE to HNSKY using the left mouse button. So position of the objects can be compared. You have to own the Realsky or DSS CD's to use this program. Manual or DDE controlled Realsky image viewer. Click on an object and get the realsky image (you have to own the Realsky or DSS CD's). Click on the Realsky image and to center to get cross at HNSKY at the same place. Version 0.9 2001-9-13. Here a screen shot demo

2001-04-25   Hnsky v2.08b. Fix for reading GSC 1.2. Some GSC files with a header shorter then 100 bytes caused an error in the program. Fixed.

2001-04-21   HNSKY v2.08

- New graphic windows for dark skies and solar system tonight. This replaces the old style with characters. The reason was both remarks from users but also my new 19 inch monitor. Using large fonts in Windows spoiled the old style info window and it was time to make it font independent.

- Fixed North function. Now you can fix the chart orientation with North, South, West or East always at the top.

- RA/DEC information area and time area are sensitive and a mouse click bring directly the required change menu's,

- HNSKY is now capable of reading the binary GSC 1.2 (303 Mbytes only). In fact I used only a small part of the GSC 1.2 for testing. This part was downloaded using my modem. I still do not own the complete GSC 1.2  If anybody can help me with a complete copy of the GSC 1.2 that would be most helpful !. It can be downloaded only by internet. See the HNSKY helpfile for the internet addresses.

- Small correction for magnitudes (about 0.3) of the main planets. (Somehow a factor changed in my source code)

- Adjustable font and individual font sizes.

- Small color improvement in printing routine.  

- Correction for lunar eclipse. Aberration correction for SUN and MOON in Earth shadow added. Eclipses should now be correct within one maybe maybe two minutes.

2001-04-12  EXPORT.EXE GSC conversion, version 2001-4-12-cThe utility EXPORT.EXE has been extended with the possibility to convert the GSC 1.1 FITS format to the same binary format as the GSC 1.2. This means the GSC 1.1 in this format takes only 303 Mbytes on your harddisk instead of the 2 CD's , 1140 Mbytes total. The quality of the GSC 1.1 stays the same. It would be still nice to have the new GSC 1.2 which has been corrected for several errors in the
