Dave, I was just doing some calculations to see how much light you had available (your 255mm mirror vs my 368mm mirror) to see if that's why you were down at 7.5fps. I know the DR2 can do better.
ps are you using Windows? If so then you should try Torstens FireCapture, it unlocks the extra gain on the DR2 and lets you go up to 36db :-) Much better than the default 24db ceiling. The noise will probably limit you to about 30db or so, but still a good improvement.
If you're using Linux then Coriander can do the same unlock on the extra gain.
Ok, so the calculation shows that you have about half the light gathering on your scope compared to mine, and I'm doing 30fps on Saturn so I guess 15fps is a good rate for you.
cheers, Bird
