Allan, the trigger for this thread was indeed your post. Perhaps rather than posting small crops you repost the full image with your adjustments proposals but maybe contact the OP first to see if that's ok as your personal view of what might be an improvement could well differ from that of the people who posted the original? Whilst the small crop proves the point from a contrast detail point of view, the bigger picture represents what the OP intended when they processed the image.

Also, wondering if because the original image was HaLRGB, that might explain why the red was off over to the right and why the op left it like that? That's more a technical point, maybe someone can chime in on that?

Cheers

You're probably right,
It's just that by the time permission came along -
perhaps 2 days later I couldn't be bothered
going to all the trouble
of making a comparison picture.

I actually feel that taking a small crop out of a large picture
is not as bad as taking & altering someone's whole picture
plus the whole picture wouldn't fit inside the
200KByte guidelines at the original pixel scale.
I'd have to post it on Astrobin & give a link.
It's not my intention to adjust someone's whole picture
just to show my point.

As for the red.
It's unusual that the RGBs are not balanced.
The Red is all out by it self as a separate hump -
it looks strange & red takes over the picture
totally obliterating all the contrast.

Normally you go ctr L in Photoshop & move the LHS slider to just before the first hump -
leaving a tiny gap - in each colour channel.
The line along the bottom is just noise.
In this case the bottom line for red went half way across the screen.
That can't be right.

cheers
Allan
