It looks great now. Not only star colours are better, but also it seems to
have a lot more signal than the first version.
Actually OIII is somewhere between green and blue, so depending on the
bandpath of the colour filters it can look either green or blue. Probably it
should be somewhere in the middle, which I tried to achieve in this image,
where I used OIII both for the green and the blue channel:

I managed to get it more smooth, but the nebula turned a bit greenish now..
On the web you see m27 centre in blue or green, wunder what the actual
color
would be..
But the stars are more natural to see.
Don't you agree Stefan?

Dirk,

the colour of the nebula looks good to me. Stars are quite blue, but
"true" star colours with narrow band filters are very difficult to
obtain.

Hi all,
I know not beautifull as the one from Rick but sure a try..
Composed out of 3 images in H-Alpha, OIII and Blue...
This one is my first try with my homebuild camera to take color shots.
I must say the actual imaging is less work than the edditing afterwards.
But i think i managed to make it look good in color.

10" SCT @ f/6.3
HOmebuild CCD camera
Total exposure time 84 minutes.
