Description

While I had trouble with banding and excessive noise with the QHY 183C in earlier attempts to image with this camera, I think I've finally discovered some settings that work well with my setup. For those who are having noise and banding issues with the QHY 183C, try increasing the exposure time and lowering the gain/offset numbers slightly.

For this image, I used the following settings:

Exposure: 180 secs X 70

Gain: 10

Offset: 25

30 Darks

35 Flats

For some reason, I had banding and noise that wouldn't calibrate out with 2 minute subs.

I hope this helps.
