History of the HNSKY planetarium program.
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.
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
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.
- 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.
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.
2016-2-14, Version 3.2.1a, improved protection against bad FITS files.
2016-2-4, Version 3.2.1 Allowing
access to Axel Mellinger low resolution sky survey. From the
pop-up menu select "Get DSS image from internet",
"Skyview" for downloading wide field FITS files. If
you select a field larger the 3.5 degrees height it will
select the Mellinger survey. Default is the MELL-R (red) of
2016-1-31, Version 3.2.1ß4. More improvements. Yo can also try halpha survey by modifying download link. Maximum field is limited at around 140 degrees by Skyview. Minimum pixel size is 350x350 unless you pull a box large then 350x350 pixels. For better quality add &sampler=Lanczos to the Skyview instruction in settings.
2016-1-30, Version 3.2.1ß3. Allowing access to Axel Mellinger low resolution sky survey. From the pop-up menu select "Get DSS image from internet", "Skyview" for downloading wide field FITS files. If you select a field larger the 3.5 degrees height it will select the Mellinger survey. Default is the MELL-R (red) of the survey.
2016-1-25, Version 3.2.0b Dropdown of comboboxes has now variable width. Fixed statusbar message flickering during animation. Fixed minor problem with trying to pull a mouse rectangle during animation. Added a half second in the routine for UTC hint to fix a rare problem in julian date to string routine.

2014-7-14 Release of version 2.4.1 No changes compared with version ß3
2014-6-29 Release of version 2.4.1ß3 Total overhaul of the bold and density function of star plotting. Start with the bold/density gliders in the middle. Note that faint stars are displayed as a single pixel with grey level so they are not so explicit vissible. Secondly improved simulation of conjuction of jovian moons. e.g. In case of conjuction of Callisto with Ganymede, Callisto can be both in the front or behind Ganymede.
