This is a full monty application of three hours' Ha to the previous LRGB rendition. For a final keeper I think I'd tone it down a bit but the hell of it here we go!

NGC6946 HaLRGB, TEC140/EM200 and Altair Astro115/iOptron IEQ45. Atik 4000 mono and colour. 12 hours data in all.

That's added a bit of zing to the red regions Olly.

Am I right in assuming that the Ha is added to the red at 100% opacity?

I think it looks good, and it's an artistic judgement that's involved.

On mine, I added it at 50%, but on my recent NGC4449, I added Ha at 100%.....it's what feels right at the time.

Cheers

Hi Rob, yes, that was added to red at 100% in blend mode lighten. In truth the Ha was not very good and needed new darks, which it didn't get because at 15 minutes it takes a bit of organizing when it is 32 degrees outside. I'm doing them now. I did keep a version at 50% too but was feeling a bit jazzy! On the French forum it has provoked a certain level of outrage but also won a few admirers so you never can tell. I won't make a habit of it but, this once, why not be a bit of a tart!

Well, that's what the camera found. Or cameras, actually, because the colour came from RGB in the mono and a one shot colour. The Ha regions are an add on but the star colours seem to me to confirm that it must be about right. Just a lot of it!!

I've been looking at NGC6946 for a while, it's a faint rascal of a galaxy to image, but it's on the agenda... Nice image BTW Olly..Beautiful Colours..

So whats the verdict on the Altair mount by the way? Can't understand why this would cause outrage on an forum, I love it, super shot.

Tom.

Cheers Tom. Outrage, well I'm exaggerating maybe, but I got an earful over the saturation, that's for sure! It's a different culture on this side of the Channel with much more forthright constructive criticism. I quite like that, actually. You can learn more. Came as a bit of a shock at first till I got the feel of it.

Now I can't possibly tell you about the mount, can I? You'll have to buy the mag!
