Return to the Coma Cluster

[Roy Batty]

It was a month or so ago that I originally had a go at the Coma Cluster, but on that occasion I used the ED80 and was dissapointed with the result. So a couple of days ago I brought the C8-N to bear on this target and got just shy of 2 hours of subs.

The processing was challenging, as there was a fair amount of LP to deal in about 50% of the subs with the target heading west (my worst bit of the sky).

I'm not saying how many versions it went through before I was satisfied, but less than ten . Still don't know if it is tad too blue still:icon_scratch:.

cheers

There sure is a lot of galaxies in there!

Yeah it does look a bit blue. This looks to be a very tough target indeed.

Thanks Arran, there's probably more galaxies in this shot than stars:)

Looking at this on my screen at work I think both the red and blue channels need to be reduced as I think I can see a magenta hue going on.

Back to photoshop for me tonight then;).

cheers

Nice capture Kieth...

If in doubt... make sure you have the info window visible in PS/CS and hover the cursor round the background and keep an eye on the RGB values...

This image is showing G around 12-13 R 19-21 and B 24-27

Thanks for the advice Peter, I posted this up on my album late last night. With hindsight I should have slept on it

Still a cracking shot, plenty of galaxies visible.

Ok here's the tweak with reduced levels for blue and red, I think it's a bit more contrasty now as a result and I'm pleased with result
