Thanks Dave. Never considered an SCT or MCT a viable option, but I suppose, why not. I've never looked through one before though, except for Xtreme John's Meade.
The Dob just doesn't perform on demand even after having been outside for an hour. I'm sure it's a problem of cooling. The scope is stored in pretty much the warmest spot in the house (no room anywhere else).
How much of a problem is cooling with the closed tube designs of SCTs or MCTs? And what's the advantage of SCT over MCT and vice versa?
PS. I should remove the "not-so-" from the thread title at this point.
