An M81 stack to show off your image processing skills

[themos]

3hr44mins of data, I am too intimidated by all the processing options, so here's a chance for anybody who likes that sort of thing.

Looks pretty good to me anyway! I thought it was going to be straight out of DSS or something.

[themos]

It is but I stretched it a bit, maybe I should have provided the unstretched one.

[shaunster]

probably unstetched is best if you want to see what people can do with your data

Here's mine.

Would like to see a raw stack though.

Here's an unstretched stack registered in IRIS

and my attempt to process it with PixInsight, I think the colours have ended up a bit muddy...

If and when i stack with DSS, i just go for all the default values.

In time i will learn to use them to the best but for now they seem to work.

Here's my efforts.....

[Cloudwatcher]

Is there a prize?

[themos]

I like robbieince's way with the brightness in the spirals and cloudwatcher's colours. And pook has brought up the HII regions well.

If we had the processing scripts...

[themos]

I've restacked fewer frames in DSS, keeping the best and had another go with PixInsight LE

And mine. 5 minutes in Pixinsight from a complete pixinsight novice.

Very nice dust lanes near the core, there!
