Eta Carina with QHY8

Hi guys,

Here is my color Eta Carina with proper flat and bias frames.
http://picasaweb.google.com/ozstockman/QHY8/

Total exposure length: 1h 15 min(10x450sec)
Imaging scope: ED80 f/6.8 with fpl-51 glass
Imaging camera: QHY8 (offset:158, gain:91%)
Guidescope: 8" SCT reduced to f/6.3
Guide camera: QHY5

Autoguiding was done with PHD and ASCOM EQMOD. It seems it really works as good as "on camera option"

Frames including bias(x5) and flats(x5) were all taken in MaximDL/CCD.
I used DSS for staking with special settings for QHY8 FITS files and "Create super-pixels from the raw Bayer matrix" as Bayer Matrix Transformation method. Final processing was done in PS.

Disregard bad stacking in the bottom left corner of the picture. It seems that something went wrong during stacking and this is why stars in that corner look bad.

Many thanks to Narayan and Terry for their help in this thread
