Wow - Humayun, what a corker!

I think that the composition is great. NGC2070 is really well balanced in this crop with the NCG2074, 2077, 2048 and 2080 (Ghost Head Nebula), etc group. The colours are very nice and a flattener will likely correct the rest that you mentioned for next time. This result makes me want to stick my DSLR back on and see some colour! LOL!
Top effort mate. I'm having a look at IRIS too - looks like another steepish learning curve, but what the hey!
Apart from the comeraderie, this certainly makes it worthwhile staying up 'till dawn huh!
