in DS photography, all the softs used to make your images, run natively under Linux. (Kstars/Ekos/INDI, Siril, Gimp ...)
In Planetary imaging, the best softs used, run natively (and only) under Windows (AS!3, Registax, Astrosurface ... )
Wine isn't really an option as it cripples literally the performances of the programs. (slower, incomplete functions, impossibility to use the output of a program as an input to another... )
So a planetary tab in Ekos will have to work at its best under WINDOWS ...
