I have now Stellarium Mobile running on my Sailfish device (Moto G4 Plus). It is now usable and doesn't crash anymore.

There are still major bugs that I need to resolve before thinking releasing this into public:
- GUI elements/buttons and skycultures are too big. Need to find some global scaling factor setting?
- Nebula pictures are not shown due to incorrect storage path defined somewhere I have not yet found.

Bonus:
- Artificial satellites are supported!

This is pretty much full/complete stellarium and rpm-package weights ~64MB. May need rather capable device to run properly. (On my octa-core 4GB RAM Moto G4 plus it works quite smoothly.)

The GUI is same as you can see in Android version.

I have looked at the Stellarium SF as well but it might need more work to get working. It works on Sailfish emulator (which uses SW OpenGL renderer?) but fails on device supporting HW OpenGL renderer. It might be easy fix? Hard part is to find it...

EDIT: Nebulas are working...
