Having missed out on the transit of Mercury due to cloud, and having been geed up by watching that doco on the sun last week, I have been wondering about those Coronado scopes. They are horrendously expensive (a 40mm PST is $995) and would I really see much more from it than say my 8 inch SCT with Baader film that I made for it? The Coronado has H alpha filter of 656.28 nM which claims to let you see all sorts of wonders like prominences. eruptions etc.
Suppose I put the Baader film on my 8 inch and get a cheapo H alpha eyepiece filter from Bintel for $250 - would that help? I dont think the Bintel filter is supposed to be used for the sun - is it???
An aperture of 40mm sounds awfully small though. Have any of youse good folk out there got some advice for me??
