Hi All

I though i would have a go at something i never did before. Stacking barlows. At 4" of aperature (even though its an APO) i'm somewhat limited for image scale. I
figured i would give the barlow stacking thing a go to see what would happen. I stacked a cheap 2x barlow into my 2.5x powermate and inserted the webcam nosepiece into the 2x barlow. This is my best Saturn image in the short year i've been doing AP.

Shoot Data:

Scope - Stellarvue SV-102 4" apo
Camera - Phillips ToUcam 840k II - 5 fps, 1/25 sec, 70% gain, 50%
brightness, 10% gamma, 50% saturation. Auto white balance.
Mount - Losmandy G-11
Exposures - 367/600 frames with Registax

Thanks for looking
