Hi folks - time to get the Redcat and 5D out for a bit of wide field. Centred on M81 & M82, here's 10 hrs of data to expose the integrated flux nebula. Nightmare to process but I'll call it quits

Value your opinion @Graham - any better?

For what it's worth.......my last iteration of this image which corrects the vertical lines (turns out to be severe Canon banding noise - removed in Pixinsight with a combination of noise reduction to

Great wide field image Chris.

What has happened to the colours ??

Probably my inadequate processing - I guess I'm trying to get the foggy neb which is a mix of brown dust and white haze on the images I've referenced

Doing very well to get the IFN at all.

Could I suggest a touch of noise reduction.

 

Not sure what the lines ar in the bottom corners.

i'll give it go......

I did download it and in PS created another layer altered it to softlight and used a median filter set at 50% with opacity tweaked down to about 50% but it did not solve the lines in the corners.

 - and at this point I'd be reaching for the clone-stamp tool. Only thing I can think is I use a utility in Pixinsight to reducing Canon sensor banding noise which is pretty good- may be an artefact from that. Cheers

You might want to have a look at Topaz labs denoise- try the free trial

I’m going to try a re-stack in Pixinsight. Those banding lines aren’t in my subs or calibration frames.

For what it's worth.......my last iteration of this image which corrects the vertical lines (turns out to be severe Canon banding noise - removed in Pixinsight with a combination of noise reduction tools), noise reduction overall, star colour balance and a bit more subtlety in the colour of the galaxies. It's no award winner but it's a keeper. Thanks for your comments folks - I'm inspired to improve

I think I like this one better too. It's a lovely widefield and there's at least 3 fainter fainter galaxies that i've counted in the there too. 

 

If I ever get half as good at imaging as you and the others on here I'll be happy.
