Celestron and Meade pretty much put the kabosh on anything Cassegrain. Fact is they use plate glass optics and aluminum tubes, which together pretty much insures that you are constantly fiddling with the focus knob. Plus you have those nice heat plumes that run up the baffle tubes. Do people know that's happening? Do they really care? Probably not because they got them brand new and shiny at ridiculously low cost. And somehow they can make them work, although I'm completely baffled how they manage it.
I agree. It is kind of a shame that the EdgeHD (or equivalent for Meade) is the best SCT we can get right now. It would be nice if someone could make a better mouse trap. An SCT that didn't have all the cooling issues if for once and for all the could solve the mirror flop issue while still being able to focus without locking the mirror and useing an external focuser. It would be a game changer. That said, I am sure it would end up costing 3 or 4x what a EdgeHD or simular would cost, so seems we are stuck with what we have..
