Linux version of the Hallo Northern Sky planetarium program.

Recommended Posts

A Linux version (beta) of  the free "Hallo Northern Sky" or HNSKY planetarium is available. 

webpage:

http://www.hnsky.com/software.htm

It is compiled for AMD64 and the  executable is "hnsky". Just unzip the files somewhere at your home drive.

Any feedback is welcome.

That was not in the planning. However what operating system are you using on the Raspberry pi? If it is supported by the Free Pascal Compiler it is possible.

In the next days, I will release a Linux version of ASTAP (Fits viewer and stack program). Then I will start working on the development of HNSKY version 4. It will have an improved swipe functionality  (like the ASTAP viewer) and some other minor things.

Yes you would be able to install it. :icon_biggrin:

The Linux Mint will be no problem. The processor in the Raspberry is ARM. Since I don't have a Raspberry, I need a ARM environment to run it in.  There is an emulator QEMU. I will have a look if I can get that running. Lazarus/FPC can compile to ARM, but i have no idea what compiling problems I will face. This is what they call unexplored territory. No promises.

For my information and understanding, how is the Raspberry used in your setup?

I have found QEMU to be painfully slow (to the point where it wasn't really usable) when emulating the RPi.  If you succeed in making it work I'd be interested in hearing how.

True.  You can speed it up by using hardware acceleration, if your machine supports Intel-VTX / VTD or equivalent.  ☺️

Doesn't look like I tried that last time, so I'll give it a go.

I believe this only applies to an x86 guest on an x86 host. But virtualizing the Pi is an ARM guest on an x86 host.

Hi there, you cannot virtulise ARM, unless you use full software mode.  You can, however, virtualise the RaspPi's O/S (RaspBian).  This will allow you to install the software and test.  Hope this helps :)

Before I put effort in this a possible small adventure, I have to know if a ARM version is usefull for some users and secondly if I can simulate the RaspPi environment.

EWHB, what is the "full software mode"?

An other solution is to just buy a Raspberry PI to play with.

support seems good: http://wiki.freepascal.org/Lazarus_on_Raspberry_Pi#Raspberry_Pi_3

I run planetarium software indoors on the client machine and that's an AMD64 running Linux Mint so no problem.  I use the Raspberry Pi as server on the imaging rig.  Currently using KStars on  the client machine but good to see alternatives :)

That is what I think a typical setup and confirms my impression. Planetarium programs are mainly run on an AMD or Intel processor system. When I look to the download numbers of the ARM version of CCDciel they are very low. For the next months I will work on version 4 of HNSKY.

As a test I have an old RaspberryPI operating system (2012) running under QEMU. Lazarus (0.9x) and FPC (2.6) are installed. While the compiler is too old,  compiling HNSKY gives too many error messages to solve. With a new Ubuntu image I have other installation problems under QEMU. If somebody can build for me a running QEMU  image of Ubuntu of Debian ARM version including the installation of  FPC & Lazarus, I could retry it.

HNSKY 4.0.0 is in the beta stage and almost finished.

      The major changes:
      Program:
      - Improved swipe functionality.
      - New improved telescope cursor, the telescope position is now shown as a correct sized and orientated rectangle. Orientation can be set manually with mouse wheel while holding CTRL key down.
      - Added possibility to design mosaics. (measuring frame on, hit HOME. To remove rectangle hit CTRL+DEL)
      - Goto menu has "slew to" functionality if "track telescope is on".
      - Three-state check-mark for asteroids and comets. Grayed=all, checked=auto
      - Three-state check-mark for star names. Off=bright stars only, Grayed=supplement stars only. Checked=All star names.
      - Vizier online server for star catalogue can be set in settings.
      - Server link with APT en CCDCIEL.

      Catalogues:
      - Added PPMXL online star catalog.
      - Added Lynds (LBN) supplement containing 1125 bright nebula as supplement and brightest to the deepsky level 3 database.
      - Added Hickson Compact Groups of Galaxies (HCG) as separate supplement and to the deepsky level 3 database.
      New telescope rectangle:

      Hello.
      This is my first post here and I wish to introduce a little program i wrote.
      This is a RAW to FITS batch converter. Converter supports many cameras vendors: Canon, Nikon, Pentax, Fuji, Konica, Hasselblad and so on.
      May be useful for someone who shooting space with DSLR and wanna do a real science, search for variable stars for example.
      Program is very simple (see attached screenshot), you just set input directory, output directory and few conversion options.
      You can choose how to process color channels from the RAW file.
      Possible options is:
      - convert RGB to avarage grayscale
      - store all three channels as separate images in a one FITS.
      - store all three channels in a separate FITS's
      - store only one selected channel
      Converter supports multithreading conversion, depending on your cpu/cores count.
      All data you entered in UI will store in FITS header. Some data (like exposure, date and camera model) may be acquired from the RAW file, this is preferable.
       
      This is a free software licensed under GPLv2 license.
      You can get it on github: https://github.com/olegkutkov/Raw2Fits
      Program uses libraw library and i highly recommend to get latest stable version of this library instead of using your distro version. If you have multiple LibRaw versions on your system - please carefully check which version you linking and using in runtime. Correct Makefile if needed.
      Libraw version older than 0.17 may not correctly extract EXIF data from the RAW files.
      Also you will need cfitsio, any version is Ok.
      User interface is built with GTK3 toolkit and tested with Gnome 3, Mate and Cinnamon DE on different Mint, Debian and Fedora distributions.
       
      After executing 'sudo make install' command this program should appear in your Applications menu
      Hope this program will be useful for someone.
      I will be glad to hear your feedback, propositions and bug reports

      Hi all, 
      Not sure I'm in the right place or not but I was hoping someone could help...
      I have an Altair Astro GPCamV2 and the box tells you to get the software from http://cameras.altairastro.com/ and that it will only work with Windows!
      I was wondering if anyone else has gotten this type of cam working on a Linux os before and what the steps were for doing so. (Other software that will work, terminal commands for the drivers etc.)
      thank you in advance ?

      Hi everyone.
      I'm currently running Linux on my laptop and just wanted to know the best stacking software is for an amateur to use.
      I tried installing registax with wine but it didn't work.
      I've tried out PIPP and didn't really get on with it.
      So far the only one I've gotten my head around is Siril by free astro.
      Would like to know what other software there is that works well on linux that is good for amateurs who have just started playing around with this.

      The "Hallo northern sky" planetarium program, a PC application has now a swipe screen functionality. Here a short Youtube impression:

      https://www.youtube.com/watch?v=evzHu73Yvjg&feature=youtu.be
      Swipe can be switched on/off in the settings menu. (ctrl-E)

      Comments, user requests and feedback are welcome.
