Here is a photo of last months moon taken in daylight to test the baffling and quality of my iStar 127mm f8 doublet. Photo taken with my Sony a200 at prime , 1000mm . Shows a very good pass on both counts , I think ? Comments welcome . Brian.

And dark , I am still amazed at the lack of CA and the contrast this scope produces , a top Luna scope . Man I love it . 2nd shot is cropped only of another shot. Brian. Attachments:

Thanks for posting Brian. I know a lot of guys despise the moon every month but why? I never get tired of a medium to high mag eyepiece and just slowly moving around the surface looking at every detail. I remember as a kid thinking when they landed on the moon that was going to be the end of the thrill of observing it. Didn't happen. Still love to observe and image it. The only time I was ever offended by CA looking at the moon was through a Celestron 6 inch F8 (CR6). You know, the one they sold a hundred thousand of? Quality really varied with those. I've heard some guys give them praise but the one I looked through had enough CA to make you barf. And Jupiter, nothing but a purple ball. I wondered if that was just a bad example. Too many guys liked them not to be.

Thanks Mike , as I say I am continually impressed with this iStar objective in its ability to thro up awesome images , easily topping 300x plus with minimal CA , just great. I am also looking forward to the next lunar viewing cycle due to start in about 7 days , I love it as well . Brian.
