Hello,
Unfortunately Ekos is not as good for planetary imaging as for DSO (at present stage).
In fact I gave it a try and my first Jupiter wasn't that bad...

I however want to try some more planetary-oriented applications.
There aren't many for RPI (I am using RPI4 with SM 1.5.4).
Firecapture and oaCapture.

Firecapture I installed following the instructions posted here.
It works but it's GUI is very slow. Not usable.

oaCapture. I downloaded the deb file but can't install it.
