Great shot Andy. Nice composition and lots of fine detail. I like the colour range.
Geoff
Thanks very much Geoff - appreciate your positive feedback

Thanks Raki - I named it after the Gemstone and Secret location in the old Bond movie "Never Say Never Again" (Last with Sean Connery) - reminded me of desert, lagoons, and those themes.
Yes tone mapped - Astro Anarchy method. I prefer this to traditional methods.
Hi Andy,
I really like it although it looks a little over smoothed with heavy processing.
I like to see a bit of noise in the picture to see where the noise floor is.

Fair point Allan, a touch too much NR I reckon- will revisit and upload a new version tmrw. Thanks for the constructive feedback andy
Thanks Marc, yes you are quite correct - and it's also refreshing to interpret a target in a different way to the usual. Cheers
That's cool. The framing and orientation does make it look like a tear drop and the cluster makes it look interesting. Couple of things you might want to check, after looking at the high res. The shot is posterised so I suspect something happened with the Oiii channel during the blending or stretching. Also you have overused either noise reduction or sharpening as the shock fronts have a plasticish look. I suspect there might be a lot more fine details to be extracted from your data and the two points above are a good place to start.
Yeah Andy, I agree with Marc, something in your workflow needs reviewing here...I've noticed the same thing in some of your other works. When viewed at the opening size on Astrobin it looks quite ok, even great ... but once the larger file is opened the issues become very clear
Perhaps the smoothing/noise reduction is too heavy or the ddp stretch or curves...? Not sure but can you see what we are talking about?

Hi Mark - first let me thank you for your honest constructive feedback - it's much appreciated when trying to aim for a high quality image. I've revisited this with much less NR - let me know your thoughts. Cheers Andy

Thanks for chiming in Mike - I always appreciate feedback as it only helps me to improve - I have to remind myself that this is only my second year of AP and there's still so much more to learn - anyway - new version below, would value your thoughts on the revision with way much less NR.

The smaller images hide the problems.
Thanks Paul, and agreed on all counts. - Methinks the big boys like yourself are being very generous with your constructive feedback - I'll take it though, many thanks - please see revision below.

Revised High res file here - http://www.astrobin.com/153116/C/
Another colleague has suggested the stars could be improved as well (dark haloes) - no problem, a reasonably simple fix, but that's something that will have to wait until tmrw night.
Thankyou one and all for all your input thus far
Gotta love the IIS community
Andy
No I don't think it is the noise reduction or smoothing that has created the paint by numbers look...not sure what it is but my guess is it is being caused by a filter you have used or aggressive curves...?

No worries Andy. We're all learners and that's the way to do it.
Agree with Mike. Although the details look a little better there is still something going on with the colour channels. This happens when you stretch 8bits pictures and the histogram starts combing. It might be caused by your processing flow. Couple of questions.
Did you work off 16bit files to start with? I assume that if you've used tone mapping from astro anarchy then you've worked the channels in 16 bits correct?

Hi Mike, yes I think you're on the right track - seems most of the smoothing was from the selective colour layer. New version below - just a very basic process and assembly only.

Hi Marc, yes 16 bit workflow - but as mentioned above - the bold colour shifts with selective colour layer appear to be the root cause. I've posted a very basic reprocess below - just assembling the 3 channels and some colour tweaks but not much else. I'll have to find a method to get the colour I want with a less aggressive approach. Interesting - thanks again for your input - I'm reasonably confident of a sharper final result forthcoming.
Andy, may I ask what program(s) you use for your processing? And even better, do you have a workflow or something like that? I always like to see how other people make their images and see if I can improve mine.

I've already commented on this excellent image but also wanted to say its very clever framing that makes this image. Gabrielle Mistral is a rather boring object but that rippled wave of Eta Carina is stunning and the colour is high impact.

I agree, it looks like a deep sea vent on the ocean floor
I think you can get the best of both worlds if you blend in your detailed shot as 65% LUM on top of your original color.
+1, I was looking at this image. This one is spot on.
Its hard to go past the free Astrodon Narrowband tutorials. You have complete control over colour with that. As far as smoothing goes - yes its a bit like oversharpening (a little goes a long way) With smoothing too much is plastic and too little can be a bit noisy - a processing balance or mega data - your call. Best to do selective noise control like with any processing, selective areas that need it (dim areas) is always the way to go.
I still like the first rendition, a beautiful 'mural'.
Thanks Kunama

Good idea - I'll try that and a complete reprocess as well and see what gives the best result. I suspect it will be worth spending the time to get it right as I'm keen to print this one.

Thanks Greg, but credit for the original idea goes to Stuart, (Rat 156) He was also gracious enough to lend me a hand on site at LMDSS when I was capturing the raw data. Thanks for your feedback though

Wow, thanks for the tip - awesome - I'll go look for those now, cheers
