- Linux version 3.3.3k_FPC (amd64 and i386)
Reintroduced 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.

Added 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.
Linux version 3.3.3f_FPC, fixed in Settings menu the dropdown
list of non-English versions.

several minor corrections.
2017-4-9, HNSKY 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.
2017-4-7, HNSKY version 3.3.2.
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 updated.
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.
Excellent translation work by Roberto
2017-3-8, HNSKY Linux version 3.3ß42. Fixed a

there is still an traditional input. The midnight button is
now setting 23:00 hours. since 24:00 hours is not allowed in the
- Automatic daylight saving adjustment for time zones
in the setting menu
PST/PDT, MST/MDT, CST/CDT, EST/EDT
Europe: GMT/BST CET/CEST
The daylight saving is based on the current valid rules and works from
20.000+. No effort is made to follow historical changes using
a so called Time Zone Database. Using the function buttons F3, F4, F5,
F6 it is possible to step through the daylight saving dates changes.
- Uses the decimal separator dot or comma as specified in your
(Windows) system settings . However the dot as separator is always
Both the daylight saving and date & time menu took significant
effort to implement. Please review and report any bug or

star database format. Reduced file size again with 10% and
17%. Each star in the Gaia or U16 databases takes around 5
bytes disk space. These database versions are compacter but
there is no gain in speed. You could keep the older databases for time
being. For technical
details see the help file
. Made the star plotting routine a
little faster. Disabled the mouse find function for disabled deep sky
HNSKY version 3.2.5a & Linux 3.3ß30 and new compacter format

7 to 6 bytes saving 14% space. Works only with very latest HNSKY
versions 3.2.5a en 3.3ß30. These database versions are
compacter but there is no gain in speed. You could keep the old
databases. For technical details see help file.
