Budgeted EP
My LB's focal ratio is f4.5. Geoff, you mentioned that a 30mm Pentax xw is a good buy, do you mean that coma is reduced a lot more in xw, and also in a Nagler? Ya, coma is a major problem for me now, every star is a small comet, and can't seem to focus to pinpoints.
Will check out the cloudy night website about the Siebert.
