The full size is showing a little bit of star elongation in

the top left hand corner & there is some noise in the pic.

I know, I don't use noise reduction, because most of the time NR will not improve an image. But I can add more data.

And I'm still struggling with my coma corrector, it still isn't at the right distance...

Elongated stars:

Are you sure the problem isn't tilt of the camera in the focuser?

It's not that serious as you can only just see it in the large size.

As for noise -

I use a mask to only take noise from the dim areas -

it works fine for me.
