Quote:Excellent review. Thanks very much. Be careful about wanting to increase the size of your Mewlon. Going bigger is something I find myself always wanting to do but it can cause problems. Would the 250 be OK on the Ioptron mount? Would your seeing allow it to outperform your 210 on most or only a few nights a year? Would it reach thermal equilibrium in a reasonable amount of time? 8" of aperture in a collimated, scope with good optics and at thermal equilibrium is a fantastic lunar/planetary and double star scope!Agree completely with you on the binoviewer. They really transform lunar and planetary observing for me.Congratulations on a great scope. Hang onto it!!best,JimP
Quote:Tim,I really enjoyed your review, makes me want to sell my TOA-130 to fund a Mewlon!Regards,Bill

Quote:Tim,Great review! I don't have a Mewlon, but I do have a MiniTower that I love. I use a Starizona Power Pack, which I attach to the mount with velcro. Works great, lasts several hours, and like your setup, no cable wrap. Starizona Power Pack II+
Clear skies, Scott my scopes: a few refractors (50-102mm), 2 Newts (4.5-12"), and an 8" SCT

Quote:I can say categorically that from extensive use of all of these that the Mewlon 250 is much superior than the 8 inch Meade or 11 inch Celestron for optics and visuals. The Mewlon has very dark background and higher contrast and sharpness. The Mewlons also show nice pinpoint stars.
Mechanically it is hard to compare as the fit and finish of the Mewlons is very professional and leaves the mass produced scopes in a different category.
