Aah, I hadn't thought of that - I have a reducer/flattener on my Sharpstar 107, but it still racks out a fair way (to about 68mm) for the ASI.


Having thought of that - my refractor has an OAG and a filter wheel on it between the flattener and the CMOS well - that's going to push the focus back a fair way. Perhaps I'm being overly harsh on the designers.
