Quote:Very nice picture. Why you change AT10RC to this CDK 12.5? It is a lot more expensive scope but less spot size and have dedicated flattener?Thank you very much for your nice and useful post.POP
Quote:Jared,Your ccdinspector screens inspired me to check my own equipment, especially since we both have similar stuff (great minds think alike, right ? ). I'm not really sure I understand the screens though or what they are telling me that I should be doing something about. Is the idea to get curvature/tilt/collimation as close to 0 as possible? Could you explain what the different values mean to you and what you do about them?

Quote:I wanted the 12.5" for the extra light grasp and focal length. Plus, the AT10RC doesn't give round stars in the corners of a really large imaging chip, which the Planewave does. I suspect the AT Ritcheys could do better with bigger chips if they had dedicated flatteners. They aren't really in the same league in terms of optical quality or fit and finish--the Planewave is a significant step up. I haven't done a Rodier yet on the Planewave, but just based on quick star tests the spherical correction is better.I think the AT Ritcheys are a wonderful value--I prefer them in general to the Celestron Edge scopes. The Planewave is better still.
