Very nice shot -- I like the wide FOV here. The 6nm filter really tamed the bright moon.

Here you go Nick:

Aligned my B&W jpg version with your large jpg in MaxIm DL and then replaced your red channel with my HA data in photoshop. It looks about the same as your original image. You had some nice HA data. That is a very nice mosaic you put together.
