After spending an hour on M13 waiting for M27 to clear a tree, I decided to add more data and some Tri Band filter data to the existing M27 I have. First 20 x 180 + Darks and Flats.  

Coming along niceley ron 

Thats good Ron

Nice one Ron. I'm assuming from the Triband filter image that the 'green' emission of the first image is not in the OIII band?

Green and Blue combined and Ha.👍
