I have two laptops that I use with my ASI gear. I use SharpCap for my imaging sessions. SCap on one PC lists EAF in the focuser section and I can control focus. I decided to switch to a smaller laptop and ran into a completely different environment. SCap couldn't find EAF. I went to ZWO support and found one section saying there is no need for a driver but immediately below was how to do an update. That update required ASCOM. It looks like I need to use ASCOM on the second laptop. SCap doesn't list EAF but does show my iOptron ASCOM app. If I start IOptron Commander (ASCM) it goes looking for a mount. How can I avoid ASCOM? I want to test the laptop to focuser connectivity inside my warm house rather than cold garage!
