I have a WO Redcat scope, which requires manual focus. I do not seem to be able to set auto focus reminders (using an environmental device as the temperature source) without a focuser device connected. When I hit run, the sequence refuses to continue, telling me to connect a focuser.
Ordinarily, my focuser module supplies the ambient temperature - so I switched to my weatherstick. I think the sequencer logic should work in this configuration.
