Eta carina with new QHY600

A test run of 27x 1min Lum exposure under near full moon proved to be a promising start. But as Peter ward and others mentioned in their reviews, the back focus mentioned in the QHY documentation is most likely not 100%. I will have to do a bit of trial and error to figure out the actual required back focus. With 2.5mm of tolerance with my flattener I could still see some room to adjust my adapter length.

For initial test, I have settled on
readout mode: high gain
gain: 0
offset: 30

Outstanding resolution.

Thanks Marc. Quite over sampled at .66 arc second but I thought it would be easier to sort out the tilt and backfocus issue with flattener before trying reducer.

After some more trial and error I got 40min of RGB data in each channel. Blue channel data was not as good as the rest but have to do for now I guess.

That's a really nice field. You're going to have fun with this setup.
