i agree with the others...its a very nice pic.

However, I would like to offer some feedback that the others dont give.

The image is biased towards the blue, need a bit more green possibly a touch more red, and less blue.

Normally the colour balance is off in favour of too much green, but im impressed that you have tried extra hard to make sure the Ha doesnt dominate. But I think you have gone a bit far.

There should be a presence of all 3 colours, but I dont see any green or a whole lot of red.

A good image none the less

Seventeen hours is one thing. Seventeen hours at f2 is something else!!!

I am not a narrowband expert but I like the low saturation which brings a more subtle image. There is only a trace of star halo. That also is good.

You ought to submit that for APOD Anthony. It's an outstanding piece of work. I don't know about the technicalities surrounding this Image.

All I see is a magnificent and beautiful region of deep space. Thanks for posting it.
