Hello all, I finally got to try out the Celestron Omni xlt 150r scope I scored at this years spsp, we had a bit of a go at M20 and here is the result. Total exposure time was 60 mins with a Nikon D90 the scope was stopped down to about f7.5 to try eliminate some CA without much luck. Overall I'm pretty happy with the almost coma free field, I do need a bit more practice with photoshop and for some reason my camera picked up more of the red and not so much blue. Thanks for looking.
That's a great first nebula. You have to be happy with that.
The blue colours are likely all there in the raw image, just takes practice to coax them out of hiding, though with an achro that may have unwanted CA pop up.
