Hi Brian,

A really nice image; love the framing and I especially like the blues in the core region. NGC7023 is one of my favourite objects to image although my past efforts have hardly done it justice.

I hate to be critical but there seem to be some strange 'linear' bands extending from the top of the image down toward the bottom; they are especially noticable on the left of the core. It's almost as if they are radial and the centre is way off to the top of the image. It might be my MacBook display or my eyes! I've looked at a few other images (e.g. APOD) to see if I can see the same thing but no joy. I am afraid I have no idea what might be causing them and unless someone else points them out maybe it is just me.

Thanks for sharing.

Adrian
