Hi

The attached image of Hyginus is the result of selecting 65 frames from 1800 using Registax3. The seeing last night was somewhat mediocre, or maybe it was shooting the Moon over the roof of our house after a very hot day?

Celestron C9.5
TeleVue x2.5 PowerMate
Philips ToUcam II
1/25 sec
10 fps
Final image: 65 from 1800 frames.

Cheers
