Helix with RC10 and Atik11002M Data added

This has taken me a couple of nights to get 40 minutes of each colour and Lum. Both nights I have been troubled with what initially appeared as a shift in focus.
With Helix being almost overhead focus was achieved quickly but with the first move of the mount I have discovered the focuser draw tube was moving in a sideways direction. A couple of small wooden wedges clamped the side of the focuser to the draw tube and made imaging possible.

My Feathertouch arrived today and seems as solid as a rock. I intend capturing quite a bit more data on this target includind some Ha and OIII that I hope to blend into the final image for a bit more detail and depth.

Weather permitting this should happen in the next couple of days but it won't be tonight, I'm sure.

Image info:
Camera: Atik 11002M mono CCD with Baader LRGB filters.
Scope: GSO 10" RC with the stock focuser.
Guiding: QHY5 in a William Optics 70mm refractor
Mount: Everything sitting on a Losmandy G11 with Gemini.
Frames: 40 inutes of each LRGB in 10 min exposures.
Cropped to remove the corners.

Comments welcome.
