NGC6537 aka Lobster nebula

[JohnH]

I cannot see the crustacean this is named for in my shot - this is my first attempt at the target and I think I need a few more hours on it...this stack is 24*20mins on an ST4000xc reduced to 50% resolution to keep under the size limit.

I think it looks more like a spider than a crustacean :) It looks good though, appears to be one of those areas that would benefit as a HaRGB shot. Using a OSC does make that a bit more difficult though.

Nice job :thumbsup:

That's pretty good John, lovely subtleties going on there, nice :thumbsup:

As for the Lobster nebula moniker, hmmm?..I think in the wide field view it has (slightly) more of a resemblance (http://www.pbase.com/strongmanmike2002/image/126617877/original) :question: you can kinda see the ribbed thorax look and the curved claws...certainly the (cooked) colour is right :)

Very nice John. Some nice coloration going on there. A bit of a green gradient in the bottom 1/3rd of the image from light pollution. ACDNR in Pixinsight or a run of HLVG free Photoshop plugin or simply backing off levels in the green channel will help remove that.
