stars in the magnitude range 11,5-16,0 and Miles stars with spectral
MS Windows version 3.3.3f, added to UCAC4 info the APASS B-V magnitude
for estimating star color and the calculated star temperature and class.
version 3.3.3L_FPC (amd64 and i386) Fixed a major problem with mouse
position detection (source code typo). Secondly a fix for the Linux
application hanging if no internet connection available. For the Linux
version the Skyview download link should be changed from http to https
to make it working! In version 3.3.3L1 this is done automatically.
- MS Windows version 3.3.3e- Linux
version 3.3.3k_FPC (amd64 and i386)
midnight=24:00 hours as far as possible. I was not happy with the
temporary 23:00 hours solution. The time input still doesn't allow
24:00 hours /12:00 PM and will show midnight as next day at 00:00
hours/12:00 AM. Since it is a standard module mirroring the operating system time
format it can't be changed.Fixed a problem with syntax check for supplements.

the Win10 Night light option to the night vision mode. Note this will
only work if you have the latest Win10 updates and it will take 10
minutes to reach maximum red color shift. If switches off, Win10
will take 10 minutes to restore the normal colors.2017-5-8,
Linux version 3.3.3f_FPC, fixed in Settings menu the dropdown list of non-English versions.
Linux version 3.3.3d_FPC adapted for new folder /opt/hnsky.

2017-4-16, very minor corrections in the help files.
2017-4-14, HNSKY version 3.3.3. Added access to wide field DSS images from NAO. This allows large fields up to 6° similar as Skyview. Example:
2017-4-12, HNSKY version 3.3.2d and Linux version 3.3.2d_FPC, several minor corrections.
version 3.3.2c and Linux version 3.3.2c_FPC. Some minor improvements.
The Linux version is no longer ß. Will be identified with same version
ending with FPC.
Two new features
for supplement manipulation and one could be be used to keep a logbook
of observations :
Edit menu for a single supplement entry:
1) For convenience HNSKY provides and
additional edit menu to access a single supplement entry. This
could be used to add a log or an observation in the "type" field.
You could either use an existing supplement or add a new label at
the mouse position (home key). Rename an existing supplement before
you use it otherwise a new HNSKY version could overwrite it if
See in the online help file:
Import tool in the editor:
2) New option for creating a supplement from a text list of objects.
I made this for personal use. If I copy my HTML based astro image
web page and then paste it inside the editor, the program will
process and create a list of labels with their corresponding
position. All recognizable deep sky names will be recorded once and
remainder will be ignored. This helps me personally to keep an
updated record of deep sky objects images taken. Any textual list of
deep sky object will be imported. Maybe useful for others.

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

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
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.
