Any recommendations on where to purchase a 12-14" achromat? D&G makes up to 12" and dont know about others. Not interested in paying out a million bucks for an apo of similar size. Any thoughts about China or Russia?

Having looked through my pal Al George's 15" F/12 D&G, you need look no further. Barry can- if he is willing- make an excellent objective in the size range you are looking at. It will not be "off the shelf" but it will be a great performer. My 8" F/12 D&G is still one of my all time favorite scopes.

well, as i stated in my opening question, looking for a reasonably priced achromat . . . . APM is only for the rich.

Thanks, kreig

Trying to be a little silly here, if it were me and if I wanted the big eye for the planets instead of a achromat I would definitely consider a lerge Mak Cass with properly ventilated ota.
Advantages: smaller, shorter, lighter, totally color free, can be mounted on AP1200 class mount, portable (relatively on a wheely bar)and very much suitable for imaging with no out of focus color haze. If you can get one designed and built with co. of about 26% images will be essentially refractor like, the contrast will be higher than an achromat due to total lack of out of focus color.

Thanks,
