Hi Matt, great to see you picking up a nice saturn image with the new scope. Agree with the guys, less frames to stack then less gain. Also as Asi says don't run faster than 10fps - information is lost. That said, and I may get howled down here, I'm not a big fan of using as much gain. I prefer to run longer exposure time (as high as the fps - eg up to 1/10th sec exposure at 10fps) and keep the gain down below 20%. I find this gets the light you need without the grain. Give each method a try under differing conditions and see which you prefer is probably good advice.
Good stuff all the same.
cheers,
