Hi All

I had some good seeing last night and with a good sun angle coupled with my most excellent Stellarvue SV102, it let me push the envelope of the scopes performance at f/35ish using a 2x barlowed 2.5x powermate and an ATIK-2HS w/green dichroic filter. Imaging craterlets in Plato has been a goal of mine since i got this scope last October. I finally got the seeing i needed to do it. The image is about 100 frames stacked using Gassian wavelets tranform in Registax 3.

Thanks for looking

John,

Wonderful clarity!! There are several craterlets visible. Now you need to shoot for the rille in the Alpine Valley. grin

Hi John,

Great image, I can see a fair amount of craterlets, one of the best images of Plato from a 4" scope that I have seen.

Thanks,

Wes Higgins
