Greg,
Thanks, mate.
I'm going to reprocess it and I'll do a comparison with hour-by-hour integration stacks. I'll report back then.
I had to integrate SII and OIII at 10x more than hydrogen alpha. After linear fitting SII and OIII to hydrogen alpha, so that the median background values across the three masters was the same, and stacking them, the whole image was just green. Pushing SII and OIII x10, returned the colours to somewhat normal, but, in the process, I've lost all the delicate hydrogen alpha that's spread across this field. I'm not exactly sure how I'm going to show that while maintaining the presence of the other two channels. I'll give it a go, though.

With noise reducing at.the.square root of the increase in time you get rapidly.diminishing returns. Some objects that are super faint seem to come alive
But a relatively bright nebula may not progress much.
I've never done that long on a single image so I am curious if there were benefits.

Marc,
Cheers, mate.

John,
Thanks, mate. Admittedly, I've never looked at this through a scope. I'll have to give it a go.

This is one of my favourite visual targets in a decent aperture scope.

Rodney,
Thanks, mate. I'm hoping a reprocess will deliver even better goods.
