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
