hmmm...... jase , here is the original image with 4 stops added, NO other processing. The whole gammut of flats, darks, dark flats, etc done and enough to ensure a reasonable effect.

on the one i put up originally the saturation has been upped and i did mask certain areas to stop blowing out of highlights, along with selective sharpening ,perhaps the darker saturated areas could be given a higher luminosity rating, but it aint that much different from what was captured. the exposures were 6 minute subs.... i have had a tracking issue possibly a flexure which i havent been able to nail down yet (plate which scopes are on is solid, both cameras are tightly locked, as is loccking screw on focusers, rings are all metal and i cant see the problem there... i currently suspect the tube on the big scope itself) its only small but enough to out of round the stars on longer exposures i have the guidescope on stars within the image and its not a rotation problem.... so thats why only 6 min subs so maybee i need longer to get the faint extensions .

interested in your thoughts as you now have pretty much the original image.

clive.

have added stacked image from Win 4 aip ... as i thought maybee Depskystacker had not done job properly, similar sort of result with slightly different color balance. Flats and darks applied to this as well.


EDIT putting it all in the too hard basket for now.... its a color balance issue i think, i killed all the blues trying to make it red will do it again another day
