Hi Pete
Thanks for the comments, regarding how it was taken
12x10 minutes each through Ha, OIII and SII filters (all unguided)
Dark subtraction only (no flats or bias frames)
Median combined to produce three master frames
Colour combined in Maxim DL using LRGB combine with Ha=luminance(100%), Ha=Red, SII=Green and OIII=Blue with a weighting of 1:3:2 for the respective RGB channels
This was then saved to 16 bit tiff using a gamma stretch with a gamma value of 0.7 using full pixel count
Transferred to photoshop CS2 where curves, levels, contrast, gradient xterminator, noise reduction and tidying up were used
From start to finish including callibration probably took about 2 hours
Regards
Gordon
