Jupiter f10 7/16

First of a few runs from this morning, all taken at prime focus. The seeing conditions would not allow even my smallest barlow, 1.8x to be used. RGB avis taken at 60sec, 60fps, 1/60sec, 130% gamma, Gain 600 RG, 800 B. Best 800frames each stacked, resampled at 1.5x. I have avis at 110 & 120% gammas and will try restacking at less than 800frames. For now here's the first Jupiter, improved from previous but still a bit washed out

Nice shot. Here is my shot that I took with a 4SE.

After comparing different avi gammas, the 130% was best (vs 110, 120). I also tried stacking anywhere from 150 to 800 frames and found 400 to be the best compromise between graininess and sharpness. Next time out I will leave the lymax cooler and observatory fans running up to 1 hour before I intend to image. Image is still washed out but a little better.
