I was not very content with the colour of my Dark Tower image recently. The Ha was a bit too muted and this was reflected in being asked if it was an LRGB image.
With a couple of useful tips from fellow imagers I have taken another look at the image and produced a better result I think? Still not entirely convinced but at least the Ha is visible now.
I would appreciate any comments of new processed image.
Hi Paul, I just boost the saturation of part of red spectrum (without touching blue and green) - PixInsight-colour-sat - to my taste ...
I hope you don't mind ......
Ok...the blue is too strong so you need to bring that down mate,and the green needs to come down too because It is subduing the reds.
First of all use curves and drop blue and green down grabbing the curve from the center.
When you pull down the blue you should see the yellow strengthen and when you pull down the green you should see the reds come through...don't worry about getting things perfect right,just get a good feel of things.
Balance color bios and again don't worry too much,its just getting a feel of whats happening(you can perfect later)
Now,try this so you can clearly see how the brightness levels effects you perceived color on screen.
Open the "Brighness & Contrast"dialog box in PS and switch to the individual RGB channels .
Experiment with brightness, increasing and decreasing and same with contrast so you can clearly see how brightness levels effect your perceived color!
You will be pleasantly surprised of the impact on perceived color...
I want to be very clear here mate,I'm in know way trying to dictate on how you should process your image so please don't take me the wrong way(some do)
What I am trying to show is some tools we can use so we can clearly see how brightness levels impact on what we perceive as color.

Hope Ive been able to do that!
No problem Louie, there are always more tools to learn in processing. I find more and more that there are new techniques to pick up as I demand more from my images. Thanks for the tips.
Impressive Paul. I like the rendition you came out with following Louie's tip alas the magenta stars hint you need more green in the highlights. Perhaps pushed it too far. I enjoy the deeper Ha hues but its not to everyone's liking. More please...
Thanks guys really appreciate your comments and high praise Jase.

I was a little surprised at the appearance of the brighter for a Tak refractor. Is that just what the filters and camera do?
Either way, top image
The halos (I take it this is what you mean) are I think a combination of filters, distance from the reducer and the speed of the scope now. The small diffraction spikes are most likely to do with the 8300 microlenses on the sensor. Mostly I see this with narrowband and Ha in particular, so I am guessing the halos are filter orientated, even though I have a replacement set.
For those interested this is my final image. Pretty happy with it and I will consider other narrowband data to add to it for a more interesting image.
Thanks David and Rolf. This one was a tough gig. I could not decide which I liked most. In the end I went with what I thought looked good. I really appreciate all the help that people offered.
