Hi Matt W

I can see some evidence of “onion rings”; concentric rings bunched up close to the limb of Jupiter. These usually indicate noise from high Gain settings or having your data bunched up to the left of the histogram where noise can become an issue in the dark tones.

Have a look at your Histogram when recording. The bottom axis shows 0, 127 and 255. If the main “hump” of data is between 0 and 127, then you will tend to suffer the effects of noise.

I try to optimize fps, Exposure and Gain so that the main “hump” in the histogram is pushed to the right hand side, between 127 and 255.

Cheers

Dennis
