I want to avoid exposed to atmosphere mirrors, the trouble I had to go to protect the 14ers coatings up here.. the Obs was sealed with dehudifier running 24/7 .. are any of these larger cheaper 6" refractors any chop or is the CA unacceptable for semi serious imaging... I was thinking along the lines of a couple of small WO,s if this is the case..that is if the larger cheaper refractors are crap. . Im open to any suggestion really,
