I particularly like the finely detailed elephant's trunk dust structures, similar to those in the Rosette.
There are half a dozen or so most interesting luminous structures that look a bit like large, straight or variously bent glassy rods, especially toward top left, similar to shock fronts. Not seen such things before.

Thanks, Mike. I wondered if the "glassy rods" were some artifact of the optical train but I see them in other images as well. Would be interesting to know what is going on there. I have done a little digging but not turned up any info yet.
Fantastic image Rick! I noticed the rods also and was wondering about them.
Question about the stars. They are mostly neutral in colour. I notice many NB images have a distinct cast of some sort. Did you add RGB stars at all or adjust the colour or is this just how it comes out with this combination?
Great work Rick, plenty of interesting features as Mike says (could keep him and I amused for hours) and nice point like stars...but I just don't like the insipid colours, sorry and they kinda have abrupt boarders with neighbouring colours which just doesn't look natural to me , also that grey-black area also doesn't look right to me ...It's not a bad image just not sitting right with my (saturated from hell ) eyes mate

Thanks, Kevin. I used JPM's tone map technique and removed all the stars before combining the colour data. The stars come back with the Lum but they tend to wash out the starless colour data and this is the result. It's possible to generate false star colours from the NB data but I didn't bother with that. We didn't get any RGB data for this target.

Greg.
Thanks, Greg!

One man's subtle and beautiful is another man's... Ta, Mike. I did toy with more heavily saturated versions but they didn't look right to me.
The data is very heavily stretched to bring out colours in the dim background. I believe the colours are real but extremely exaggerated. I largely hold with the PI philosophy of never "painting" data or masks and, apart from CloneStamping out bits of stars that didn't get removed cleanly, every operation performed on the image was global and based on the data values.
I agree that the black area looks a little odd but it also looks that way in other images
Appreciate your honest feedback

Oh, I didn't mean it was under saturated, just that the colours look kinda off and mostly a bit washed out I guess..?

yes, well that might explain it

Ah ok, that area just looked a bit out of context, a bit unnaturally black-grey

Good, because overall it is a good image regardless of my opinions on what are just a few cosmetic things....and you did specifically ask for constructive feedback
I may play about with it a bit more, Mike, but I'll leave it for a couple of days first. Funny how you look back at an image after a few days and think WTF??
