Marcus, it has been a long time between posts. A marked improvement on your first (NGC2070).

Indeed, slightly oversampled (though I don't know what your conditions where on the night - obviously more the 1 arcsec). Oversampled data is easily fixed with a few iterations of deconvolution to keep objects looking tight.

Your processing needs more work, you've really black clipped the red channel and subtly the green. I suspect you've set the black point to early on in your processing routine which has caused this. This is usually one of the last things I do before finalisation.

I also feel you could have brought the colours out a little more. Perhaps the use of the non-linear stretch using PS shadow/highlights tool on the chrominance data instead of curves or hue/saturation controls. You may also wish to try different ways of introducing your luminance data so you maintain a balance of luminance resolution and chrominance data.

Look forward to seeing more images with this great ota/mount/camera combination.
