I've added RGB to the previous Ha image and this is my first stab at it. I was expecting better data from the camera but unfortunately I forgot to put the cooling on - Doh!!!
Same equipment as before but with 8 x 300s each of RGB, the Ha was blended 80% to Red channel and 20% to Blue channel. Any comments gratefully received.

It's looking very good - I love the star colours! The noisy RGB data does not appear to be causing any problems.
Some of the stars appear as if they are sitting on blue discs - I wonder what is causing that?

Thanks Mark. I hadn't noticed the blue disks but I suspect it's the way I blended the Ha and Blue data so should be correctable. There was some flaring on the Blue channel which meant that the stars were slightly larger and I think that was the root cause. Camera lenses are certainly not telescopes in their performance though they should be close!
As a slight aside I used a synthetically generated flat (Pixinsight LE) and a single dark (with cooling off) to compensate for the hot pixels.
Looking very nice Robert - I was going to question the blue halos as well but you alrready have this covered... Cheers, John
Well, Robert, saw you had a lot of good data on this one, last night, very nice
