I can remove this obviously but this is the Gradient in an RGB 4 hour stack taken in my backyard in Portland Oregon last night that I left in just for fun..
The Iris nebula is on the left side.

Aurora Gradient.
Eh,
I have 1h of blood red Iris nebula
After many stacking test, I integrated the red subs in the stack withour any gradient!
It was 1200 x 15s subs so I guess the red pixels just got rejected during stacking.
Clear skies

I have to say, it gives an interesting touch to it Thanks for sharing. I was shooting a day before the Aurora, and there was still low Kp Aurora out here and realized some of my R filter images catch it. I was wondering why the final image has a red/purple tint to it…

You could say you got some Iris gradient in your Aurora subs and call it a win. CS & GB! Kip

Lol, that would be the prettiest gradient someone could have in their subs

As noted elsewhere, I’m in the early stages of trying to make the transition from what has mostly been “electronically assisted astronomy” to producing some nice images. So I present last night’s effort here for input, with particular regard to acqui...
