Do you realise that for $2300 (current price) you could have a wonderful Skywatcher MN190 Mak-Newt f5.3, 1000mm fl, . Fully corrected -no detectable coma, heavily baffled, amazing contrast, very small secondary mounted on the corrector - so no diffraction spikes. Reviewers suggest large APO performance at 1/3 the price. It is both a astrograph and a powerful visual scope. Yes i have one of these.
I have nothing against large refractors, i have a 152mm achro, and my iStar, but from a value for money perspective, true colour rendition, and apeture, it is hard to make a case for the investment required (for me) just to have an exclusive brand name on a scope. These are simply devices to enable our grasp of night sky, imho. However, i understand that for many people they become "objects d'art" and therefore the experience of having one, for them, is a reward in itself.
