Sinus Aestuum at f6.3

[michaelmorris]

I recently took possession of an f6.3 focal reducer for use with my new Canon 1000D camera. I thought I'd try it out with my webcam just to see how it performs. The dark mantle areas to the east of Copernicus show up nicely.

As usual, best 500 frames from 2000 processed in Registax 5, then final sharpening and curves in Photoshop/Focusmagic.
