Which flattener - Meade series 5000 ED80
I've had the Meade series 5000 ED80 APO triplet (f6) for a few years but have never really used it much for astrophotography. It has a reasonably flat field but there is a bit of coma at the edges. I'm wondering what flattener would be best for it?

Any suggestions?

Peter
