What’s the easiest way to check & set camera rotation? I’m using a ZWO ASI1600 on a Tak FSQ85 in a permanent remote observatory. I don’t have a motorised rotator but the Tak has a manual rotator. I understand that there’s no ‘up’ or ‘down’
but I see my images are around 180 degrees to most posted images. Best to just do by trial and error or is there an application that can help?
