Here’s a result after correct demosaicing of the raw files, dark/flat frames substraction, registration (stars aligning) and stacking:
The result was saved as 16-bit TIFF image, and then quickly processed in Rawtherapee.
The original author at astrorawdata.com did a much better job at postrocessing than I did:
Another take at postprocessing in RT, which brings me closer to the author’s version:
So, back to the object of this thread: Siril seems to work great and is IMO good option for the Linux platform.
Hello.
I am one of the developers of Siril.
If you don’t want to compile, packages exist for some GNU/linux OSes and are available here: Siril:0.9.3 - FreeAstro.
However, we are currently working on the 0.9.4 version which will be released in few weeks (I hope). This version fixes a lot of bugs and brings some new features: Change Log - Old Siril bugs. From now on, use the the gitlab project instead: https://gitlab.com/free-astro/siril
We try our best to update tutorial website but sometimes we are late.
For preprocessing, take a look here: Siril:Manual - FreeAstro
Best regards,
@lock042 thanks for your work. I followed the tutorials on your website, but there’s a lot to read! In fact I found that the help bubbles in the program, when moving the mouse cursor over the different option boxes, very helpful.
Thank you very much 
We would also be happy to host a quick tutorial or small write-up if you’d like to put something together? 
OK. I will try, but I need some time

[/quote]Built the new code from trunk. It doesn’t crash anymore which is fantastic. The alignment still doesn’t work for my (untracked wide field) shots. But I can now use the stacking which is awesome. Would be nice if I could directly feed it tiffs though. So a big thank you from my side too.
Siril use to process untracked wide field in many cases.
You can set property parameters of your star detection in Analysis ->Dynamic PSF
Cheers
Deep sky images align perfectly with 0.9.3, I haven’t tried wide field yet.
Yesterday I released the 0.9.4beta in the svn braches (siril - Revision 2589: /branches/0.9).
I hope I will find the time to build packages.
Cheers

zypper in sirilDear @patdavid.
I think you add here the Windows icon (indeed, Siril is working great with Windows now.
Also, here the icon of Siril : https://gitlab.com/free-astro/siril/blob/master/pixmaps/icons/hicolor/512x512/apps/siril.png
Cheers,
This is awesome, thank you so much for pointing me to it! (I’ll update momentarily and push).
[edit] - Now we’ve got the icon for Siril! Thanks again, @lock042!
@patdavid : Thank you !!
I did see you’ve changed the icon. But I don’t see the windows icon.
Another thing, I forgot to tell you that our new website is : www.siril.org
Cheers,
Ah, I am not a smart man. Sorry.
The correct Windows icon is now there, and the website is updated! Thank you!
HTML is hard!
I apparently didn’t get that far in my book HTML for Dummies. 
Should be fixed up now
