How are you mapping the NB filters?? Seems you map Ha to the green channel in many of your images. Try mapping it to the red channel.

In any case, it's a good shot, Antony:D

Thanks. I can not put tha Ha as red because it will be not Hubble palette then. Hubble palette is:
S2 = Red / Ha = Green / O3 = Blue
The truth is that i needed more S2 (red) frames for bringing up the Red color. Will do this in the next image. Thanks a lot again.

Superb picture! :eyepop: Details are so sharp, yet you've managed to keep the stars soft and nice. Great dat capture and processing. One of the best I've seen if not the best. :thumbsup::thumbsup::thumbsup:

I know what the Hubble palette is, but there's nothing like a bit of experimentation:D:D

It's not just science, it's art, and a good artist (or scientist) shouldn't be afraid to mix things up:D

Superb!

Great shot.

The red is probably there already and needs red channel boosted in curves (you can do individual colour channels in curves). Try that to see if it is there already.

You can also bin o111 and S11 2x2 like you do with RGB to get a better signal/noise ratio.

Nice. Last night it looked rather blobby in my scope, good to be reminded what it looks like in all its glory!

Fantastic, detailed image.

Looking forward to more of your work.
