Not a bad result on this baby Andy, good work, you have even captured a hint of the fainter jet (left one in your image), not too many images show this :thumbsup:

With 17 hours it certainly goes pretty deep! Very nice Adam :)

[Bassnut]

Impressive Adam, the hrs paid off, one of the best ive seen, much detail.

[Placidus]

That's superb! It's really difficult to get much out of that one. Excellent job.

Great work Adam. Impressive colour contrasts. Not an easy object, but you've rendered it nicely.

Thank you :)

It's been hard to get anything done this season, so many cloudy nights

[Paul Haese]

Nice colour and detail Adam.

I think that's the first bicolour NB image I have seen of this object. Great result!

Interesting colours from mapping i like it.
Those tiny jets shooting off look very prominent was worth the 17 hours great effort way better than my attempt last year.

Wow! That is superb! :bowdown:
