Alex, look into a CDK, as it has a 52mm imaging circle, and thats for stars at 1 micron. It will do much more at slightly bigger stars, but still smaller than competitors, especially against the RC which doesnt have a flat field (Unless you have the corrector lens option).
Plus the benifit of being f6.8, and with the new reducer comming in the next few weeks, the f5 i think, should do wonders for your imaging.
Plus at about 1/3 to half the cost...

Some reasons why i went with the CDK over most other designs.

Louie - yeah... mount is organised... waiting waiting waiting... Astro-physics wait list..

Theo. I have considered a CDK as the next scope.. I really like the planewave instuments scopes, and after having used one just recently (CDK20 on Paramount) I was incredibly impressed.... I've not really looked at the optical system in depth however... If I build my own scope, the RC might be easier with more of a knoweldge base from other ATMers... That said, a CDK 12.5" might end up cheaper than a home brew RC... still waiting on prices for carbon fibre and optics sets (including corrector lenses)

Thanks for the info...

(Sorry for being way off topic.. )
