Not happy with the processing yet but here is an m8 from Friday night...this with an unmodded and not cooled canon 20d - thought it might make a useful comaprison to some of the other m8 shots in here recently...

Not too much wrong with that John. Focus a bit soft, but otherwise a nice composition.

Nice one. It looks like there's plenty of data left around the edges if you wanted to ramp up the brightness. Maybe not, the brooding atmosphere of this one is good. I like your second version best.

M-8

Hi JohnH,
Ive taken the liberty of re-processing your M-8 to bring out some more of the Ha (red) that the filters in your camera dont pass.

cheers....Jim

That's nice Jim....I hardly recognised my shot...how did you do that? Hue controls? I do struggle with colour balance in processing these images - most of the modded camera images I see look way way too red to me - I would like the images to be close to "what you could see if you were close enough" to that end the unmodded camera gives you a reasonable shot (given the eye isn't sensitive to Ha)....but the red is missing in my shots and I have not found a good way to emhasise what is there without saturating the red channel...

I agree with you John, lots too much red in many images with modded cameras, but everyone has different tastes ans what they believe something should look like. I usually tone the red right down...
I don`t know what software you used but have you tried channel mixing? In photoshop if you output 10% of green and blue (approx) to the red channel it gives for a more natural reddish neb.

M-8

Hi JohnH,
I processed it in Images Plus first, then Paint Shop Pro, but Photoshop will do it all for you if you know how (I dont), also this was a Jpg picture which is much more difficult to process correctly than a Fits or Tiff (no compression), the best Image processing program ive used is Images Plus, I started out using Photoshop but could never get the results I wanted (it takes a lot of learning to drive it ) but its an individual thing.


cheers......Jim
