Hi Karl,
I use Astrotortilla. It natively integrates with ASCOM and BackyardEOS. As a planetarium I use Stellarium (an older version) and also the Stellariumscope plug in (it only works up to a certain Stellarium version). It takes an afternoon to set it all up. But would not want to go back.
When you download Astrotortilla, it downloads the Cygwin engine as well as a bunch of catalogues. You can narrow the catalogue range down, if hard drive space is an issue. If you download all, then you’re covered for everything — from a 10mm lens to a 3m cases grain or thereabouts.
I asked questions here when I got stuck and received excellent advice from Ken and the others. Have a look here, if you get stuck
