[turbo_pascale (Rob)]

I tried to do some images last night of the moon with my 80ED @ 480mm.

I shot using SharpCap and did 3000 frames each of RGB.
I did a 1760x1760 region of interest.
The images were shot all within about 5 minutes or so.

I stacked each of the three of them in AutoStackkert3, and was relatively happy with the result, sharpened out of the box.

However, I can't quite get them to line up (manually in photoshop, or in Registax6). The Red channel is off by about half a pixel vertically at the bottom of the image (at the top it is ok).

I'm struggling a bit to work out the right way to do this, and stent too many hours already looking for the right workflow steps.

I'm thinking I need to go back and stack them with a 3x Drizzle to pump up the pixels, and then I may have a bit better chance of finding an alignment.

Unless someone can teach me how to move the channels around in partial pixel distances?

These are the times I wish I had bought a one shot colour as well!

Can anyone point me to some resources on how I might fix this?
