Autofocus difficulties

Troy, you will want to start a new topic and file it under feature requests or it will be lost. We go through this category every couple months and use it to prioritize implementation of new requests. We don’t go looking through general topics to find stuff (just too many…).

It’s possible I suppose, but we do all our testing with real AF frames of M13 and M3 (exactly for this reason) and still get good V curves. Of course, there are tons more variables. Our test frames are ~700mm FL, Scale is ~1.5"/px, the scope used to capture the data was slow-ish ~f/7 and so on…

Cheers mate. For the record, 506mm f/5.5 refractor, 5.4um pixels - ~2.2"/px.
