IC2944 Narrow Band complete, 23.5 hours

[SimmoW (SIMON)]

Massive effort, producing a stellar result! Great work Paul.

[Bassnut (Fred)]

Wow Paul, high detail and smoothness. A pleasure to view. The effort shows, an excellent result.

[Shiraz (Ray)]

Very nice smooth and detailed result Paul - congratulations

[gregbradley]

I like this rendition the best. The colour to me is a tad off still though. Those cyan areas to the left side seem to weaken the impact of the image on the left side. I like the mustard tones and nice blues on the right. Plenty of detail but lacking a bit of contrast again on the left.

Lots of sharpness and detail and that GSO RC is really a very sharp scope.

Greg.

A beautiful piece of work Paul.

[Octane (Humayun)]

Now, that's a stunner. Beautiful work, Paul.

Thanks guys for the comments.

I made a small adjustment to the contrast on the left hand side. I think that works now.

[pluto (Hugh)]

That's awesome!
Great work

Yeah that looks better. Stronger in that area. There's no question these GSO RCs are sharp.

Things I really like:

• Perfectly round stars with no magenta halos (gotta love self-guide ahead of the NB filters )
  
• Beautifully smooth background with bugger-all noise.
• Good highlight and shadow control and not too much chroma.

What a great result!

Detail to die for!awesome Paul.

Thanks Louie and Hugh

Yes the optics look to be good with these scopes. It is the little finishing touches that need refining a little. Getting rid of that crap focusor would be a start, putting in a heated secondary would be good too.

Yes I am really happy with the guiding of this scope with the integrated guide head. I still think there is room for improvement with the guiding but overall I am happy.

Being able to image at -30C all the time is great. The QSI is a great little camera but the -25C limitation in winter and -20C in summer does make it hard to control noise. I could easily push the cooling on the STXL to -35C and that would make for less noise again. The sensor and electronics also produce low noise levels as you know. It all helps to produce backgrounds with low noise. Although mostly I attribute lower noise to going long on my subs. I routinely do 30 minute subs and this gives me high ADU to work with, which impacts on noise.

That's really brilliant Paul. Quite stunning.

[Rod771 (Rod)]

Well done Paul! Lovely image with so many points of interest.

Congratulations

[Phil Hart]

Sweet image Paul.

The whole system is working well together there and the processing finishes it off nicely.

Nice one Paul

Not quite there yet Phil, some tweaking needs to be done yet. I am waiting on an adapter for the field flattener that went back to the states for an adjustment but I reckon Australia Post sent it via Jupiter as it is not there yet after 12 days. Once my camera gets back here from repair, I will have to undertake collimation work again and do another pointing model check and then I can start a galaxy I have been after for years. It is nearly working to how I want it though. (did I say perfect?)

Yeah that would be nice, wouldn't it.

great shot

[steveyzh]

Great shot! Time worth.

Stars in Sii channel often bigger than others and Oiii channel easier reflecting from brighter stars. Due to SHO(RGB) hubble palette, magenta around the stars is really unpleasant. I often reduced magenta saturation to achieve better looking.

I did try OSH(RGB) for stars color only,presenting kindly of faule blue,then select stars only,blending on top of SHO layer, and make some PS adjustment to taste.

Also, taking short exposure RGB for stars and blending to SHO layer is another option.

Anyway, this is a fantastic image!

I tend to use selective colour to control various colours and either use a mask to blend in or select the level of opacity to control the hideous magenta tinges.

RGB stars is certainly a way through the problem but time consuming and doing the blend right will sort that issue out anyway. I am working on learning that technique to get RGB stars from NB data. Martin Pugh told me how to do it a couple of years ago and I don't quite have it right yet.

Thanks for the detailed comments.
