Hi. This is my first attempt at writing a program for astrophotography. My main idea was to write a program for my Orange PI that will allow me to shoot astrophoto with low shutter speeds (5-20 seconds) and perform guiding without a guiding camera.

Now the program can:

• Manage properties of INDI devices
• Take and save photos
• Calculate the parameters of the stars in the photo
• Live staking
• Mount management (guiding and dithering)
• Focuser control (not all functions work)

Future plans:

• INDI driver crash recovery
• Simple sky map
• Plate solving
• Sigma clipping for live staking (not sure this is possible with low memory usage)
• Live view from camera in video mode

Now the program is only suitable for cameras without a mechanical shutter. If you try to use it with a SLR camera, then in the "Live view" mode, the camera will clap the mirror all the time.
The program requires INDI server to be installed on the computer!

Deb package (arm64 and x64 platforms) and archive for MS Windows (Win7-x64 and newer): drive.google.com/drive/folders/17d49C9Xg...XcdNsCtb9d15nM-WBjGZ
if you want to try to compile AstraLite for your platform look here: github.com/art-den/astra_lite

PS: minimum requirements

• for astrophotography: 1Gb of RAM
• for live stacking: 2Gb of RAM, 4 CPU cores

WOW this is really cool! Is it compatible with INDI 2.0.0 as well? Gotta try it out.

Yes. It implements its own INDI API so it is compatible with any INDI server with protocol version 1.7.

Interesting. What do you mean by "The program requires INDI server to be installed on the computer!" it doesn't support network connection or?

I meant that the INDI server is not listed in the dependencies of the AstraLite deb package. Thus, in order to use AstraLite, you need to install the INDI server manually.
Also it reads devices names from /usr/share/indi

Added support for MS Windows (uploaded archive with windows binaries). To run, extract archive and start astra_lite.exe
Should work with Windows 7 and newer versions.

New alpha version 0.0.20

• Simple guiding by main camera
• Dithering
• Focusing (not fully done yet)
• Separate light frame quality options (max stars FWHM etc)
• Histogram, statistics and light frame history moved down in window
• Lot of refactoring and bug fixes

@Denis that is really amaizing project!
I have tried alpha version 0.0.20 with indiserver and indi_pylibcamera (github.com/scriptorron/indi_pylibcamera) driver. Connection to indi server was successfull, but when I clicked button "Take shot" I got this error:
Property 'POLLING_PERIOD' of device 'indi_pylibcamera' not found

See attached image.

Interesting... Please select menu "Help -> Save INDI properties...", enter file name and attach saved file here. I will look what is wrong

INDI properties in attached file.

Thanks for this file! It looks like driver for your camera doesn't support this property.
Fixed in 0.0.22. You can download and test it.

Thanks DENIS for your contribution, consult, I can download the compiled .exe from somewhere, I'm having problems to compile it from my WIN10
Best regards
Osvaldo
