Seagull Nebula (IC 2177) NB SHO

[glend (Glen)]

This is my SHO pallet version of the Seagull Nebula (IC2177). Shot with an ASI1600MM-C camera through a TS Photoline 115mm f7 APO (reduced to f5.5 here). Image consists of: 23 x 300" Ha, 21 x 300" Oiii, and 20 x 300" Sii subs. Processed in DSS and Photoshop CC.

Thumbnail attached here as usual, but suffers from downsizing obviously.

Now, this one I like Glen.

Very nice.

[Atmos (Colin)]

It is nice Glen! I've never seen a Seagul myself, only a DRAGON!

[Placidus (Mike and Trish)]

That's very fine. We like it a lot.

[cometcatcher (Kevin)]

Nicely done! I must remember to try for this one.

[Stevec35 (Steve)]

Excellent nebula detail Glen but it's almost all green. I wonder if reducing the Ha contribution might be worth doing?

Cheers

really nice work Glen, I'm liking the new imaging rig, working really nicely!

here is a pretty neat tutorial on de-greening that may help http://bf-astro.com/hubblep.htm

cheers

Yeah probably looking a little too green overall...but the detail is excellent Glen To me it is a Parrot/Cockatoo looking to the left with wings out stretched

Gotta love a ghostly green for a nebula :-)
this is a nice result, well done.

Thanks to one and all for your comments on this image, I am working hard on improving my skills in this area. I agree with Mike, in that I too see it as a Parrot, and there are plenty around my backyard that are very green.

I realise that my rather heavy handed colour saturation may not appeal to everyone, ie not fit the "Standard Model". When I search for images of the Seagull Nebula I see many interpretations and colour schemes. I acknowledge that my image library does seem to be littered with rather lurid images compared to many others of the same target. For now I will put it down to my artistic license, as it is one area where self expression is possible. My recent Rosette Nebula is a good example. Judging by the number of likes that I get on Astrobin it seems to appeal to at least some others as well.
I will review the de-greening piece linked but can't promise to change.
The problem with SHO is that there is just so damn much Ha out there, what ever colour you make it will dominate.
However, I acknowledge that shooting significantly more Oiii and Sii could tame the Ha.

Northern lights nice

[Atmos (Colin)]

Shooting more OIII and SII won't tame the colour at all, it'll just smooth them out.

What you have is a colour balance on intensity (signal strength) as opposed to an image white balance. Hope you don't mind but this is a very rough idea of what it could be.

What I was trying to say

Steve

[rustigsmed (Russell)]

That is also what I was suggesting with the link I posted.
The capture is there just some colour tweaking and you're there !

[glend (Glen)]

Actually my daughter-in-law (a Photoshop professional editor) and i were playing around with the colour balance when she was here last. Easy to do but hold that magenta off, can't stand pink stars.

Taming the magenta can be an absolute nightmare! I spent a few hours for a few days for a few weeks trying to figure out a workflow to mitigate it without causing other issues. SLOWLY getting better

Colin, Ken Crawford deals with Magenta mitigation near the end of his online Photoshop Colour Mapping tutorial; basically he clips on a mask above the CAB layer and uses it as a sort of colour balanced/luminosity layer to clobber the magenta. If your a PI user I can't comment on workflow.

And re the last several posts, as I said before in post #10, yes I acknowledge I do not conform to the "Standard Model" and this is not by accident. I am happy enough that my images do not look like the 1000th version of something everyone else is producing. After all, this is false colourising, we will never really know what these areas would look like to the human eye (other than faint fuzzies in observation). There is plenty of room for various interpretations. At the very least it gives us something to discuss.

[Atmos (Colin)]

As you said, artistic license allows you do make it however you like! As for how it looks to the human eye... Red. Lots and lots of red Under SHO... Green, lots and lots of green!

like it a lot Glen - very luminous and smooth.
