Hi there everyone.

I know you are probably getting sick of this series of shots from me, but I don't give in.
Reprocessed this one. Removed the larger stars, now I am pretty happy.
Ha = Red
R = Green
G = Blue
B = Green
About 16 hours of data

Dear Marc and Dunk,

thanks for the feedback.

Marc, Yeah I know, I only removed the really big stars.

I am expecting to acquire the Atik 11000 soon, so I am going to reshoot the whole region soon.

Are there any methods of
a: avoiding the blooming apparent in my previous images; and
b: getting those nice pinpoint stars evident in the attached image?

ANy help is appreciated

Some nice detail in the neb there, Scott! What are you using to process? You can probably tame the bigger stars a bit without removing them completely.

At that focal length to get tight stars you need good seeing and guiding. Maybe an AO. Having said that 90% of a good picture will come from processing, deconvolution, star registration etc... A change of camera will help with data but in the end you'll always have to brush up your processing skills. Takes a little time.

Hi Marc and Rick,

I am practicing with the Minimum filter in PS CS6 to reduce the stars. I am at this very moment reworking the entire image, including restacking. Will post when finished

Rick, as I said last night, attached is my hour long exposure
