Hi All,
Just sharing my thrid attempt at Saturn
Got the frame rate on the webcam down to 5fps this time (as suggested by Matt) and got the exposure to 1/33s.
Seeing was attrocious in Brisbane early in the night, but at about 2am a cold front moved through and when the cloud cleared afterwards I was able to get this image.
I think this one is slightly better than my second attempt
Celestron C8 with 2x Ultima barlow for 4000mm focal length;
Philips SPC900NC webcam at 5fps, 1/33s exposure;
Stacked 500 of 1000 frame in Registax;
Wavelet and final processing in Registax.
Have fun,
Doug
