Way to go!

Thanks Rob, only problem is finding stable seeing for about 4 hrs.

What capture rate are you able to use? I tried Jupiter last night with it filling the screen and was still able to get 60fps with the histogram 80% filled. I didn't think such a fast rate was possible with my scope being 14".

Thanks.

Thanks very much Lester. I have experimented extensively with my capture setup, especially for Saturn. My settings vary depending on the object and its altitude.

For Jupiter I use a frame rate of 30fps. Exposure for the red channel of 1/30 th sec, green channel 1/38 th sec and blue channel of 1/30 th sec.
In 40 sec's I get about 1200 to 1300 frames and if the seeing is good then I can easily use 800 to 1000 of those frames in my final stack for each channel.

I set my gain to virtually fill the histogram, I keep the hist at about 250.
At the moment for Jup my gain is around 820 to 825. Bear in mind that this is on a 16" F4.5 Newt. I have tried 60 fps but I think I get better results at 30 fps.
