Thanks Allan. It was a lot easier than I was expecting. There was no problem locating stars to align on with the Ha in place with a couple of seconds exposure and the mount/guiding seemed to go ok with 10 minute subs.

Your second go at it is very nice. The sharpening has lifted the image quite a bit.
Well done.

Thanks Doug. I might have a play with splitting the channels to see if it makes any difference.

It's all relative Jonathan - I don't have an automated dome (yet)

Cheers Troy. I started with a more mild sharpen but thought it could take more. The result had more sharpening than I would normally use however I thought it still looked ok. I was thinking about combining this as Luminance with some colour data from the other night so wanted it to be quite sharp.
