The Linux version is no longer ß. Will be identified with same

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.
2017-3-31, Introduced Spanish help file.
Excellent translation work by Roberto
2017-3-8, HNSKY Linux version 3.3ß42. Fixed a

3.3ß41 Updated the help file and non-English files.
2017-3-2, HNSKY version
3.3.1 Significant update:
- Added a modern date & time input and a monthly
calender. The calendar doesn't allow dates beyond year 1752
and 9999 so there is still an traditional input. The
midnight button is now setting 23:00 hours. since 24:00 hours
is not allowed in the current setup.
- 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 1977 (arbitrary)
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
Both the daylight saving and date & time menu took
significant effort to implement. Please review and report
any bug or problem.
Some work for the translation files is still required.

HNSKY version 3.2.6.d & Linux 3.3ß31d, overhauled the
bright star (text) find routine.
3.2.6b & Linux 3.3ß31b, introduced the 290-9 and 290-5
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 database.
HNSKY version 3.2.5a & Linux 3.3ß30 and new compacter
format for the star databases without quality loss. TYC and
TUC record size goes from 11 to 10 byte saving 9% space.
U16 and G17 go from 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
native HNSKY database up to magnitude 17
164 million Gaia stars. Note that Gaia DR1 is missing some
stars so is less suitable for star maps. HNSKY version
3.2.4b or Linux 3.3ß28 required, just released today. Unpack
in the program directory, typically c:\program files\hnsky
version 3.2.4b & Linux 3.3ß28. For above Gaia 290 star
, issued a
new version of the TUC star database up to magnitude 15.
Contains 7 % more stars due to other magnitude selection.
version 3.2.4a & Linux 3.3ß26. Fixed a problem in
reading U16 star database type 290 with 7 byte record
HNSKY database up to magnitude 16
contains 113 million
stars. A compilation of UCAC4 and Tycho-2. (RAR file of 437
mbytes). HNSKY version 3.2.4.001 or Linux 3.3ß25 required.
No Tycho-2 or UCAC4 indentifiers are available due
to 7 byte record size. Instead an IAU style designation
based on the position is used.
HNSKY version 3.2.4 & Linux 3.3ß25.
Introduced 7 byte record size in 290 database.
HNSKY version 3.2.3b, Gaia DR1 support using Vizier online
database up to magnitude 20. Gaia proper motion implemented.
version 3.2.3a, fixed an stream error if switching off
the online database. Adapted plotting range of the TUC
database to magnitude 15.
HNSKY database up to magnitude 15
containing 36 million
stars made form TYCHO-2 and UCAC4. Compressed in a RAR archive
the size is 192 mbytes. It will only work with the latest
version 3.2.3. of HNSKY since it is in the "290" format.
Abbreviation in the program as TUC
2016-08-06, HNSKY version 3.2.3
with new .290 star file format. Installer will
replace the d32 files with .290 files! This
star database format will be faster and allow larger
in deepsky databases. Improved several minor things including
corrections in version HNSKY 3.2.2g. Added new
supplement with official IAU star names, version 20-7-2016,

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

- 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
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.
