Finally got a clear night for imaging. This is my 1st time at imaging M27.

 

Skywatcher 100ED Pro with ASI1600MM cooled camera.

120 x 30s Lum, 30 x 60s each RGB - all at gain 70 offset 20

 

Processed with DSS and StarTools

 

I am fairly new to AP, so I have not figured out yet how to tame bright stars (like the one at right center). C&C welcomed. 

 

Clear skies

Nice colors.  Good guiding.  You may be able to coax a little more illumination out of the dumbell in processing.  Brighten it up and extend it a bit.

But I'm no AP master by any means.  I like it !

Very nice.

 

I'm not an expert on processing but a star make protecting the stars when you pull the histo on the nebula would help. I pull the entire image until the brightest object reaches what I want (in this case that star). Then I protect it and the other stars with a mask and keep pulling the nebula.

 

PI has a great easy tool that will build a star mask for you.....not sure about Startools but i'm sure it can be done.

StarTools does have a way to create star masks. I am assuming you "pulling the histo" is the image stretching. Not sure if I can use star masks in the module that does the image stretching, but I will certainly look into it. Thanks for the suggestion.
