Thank you Hans, I have confirmed that option 1 does work; however, it's a long process and I believe there is an error in the steps. Seems there is a mix up when it wants to create ~/Projects/stellarsolver-build directory. I think I had to create ~/Projects/stellarsolver directory and copy contents into ~/Projects/stellarsolver-build directory. I was able to get the steps to work and get an inside preview to work. Need to confirm complete functionality but it seems like a fix. Thank you siberX for the workflow.
As a side note, the astroberry OS does not come with cmake loaded. I used this link to load cmake with snaps... snapcraft.io/install/cmake/raspbian
Now I can complete setup of astroberry for all my equipment and get ready for clear skies !!
