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

IFN_V4_SM

 

Value your opinion @Graham - any better?

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 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.

I bet you can't unsee them now, sorry.

don't apologise mate, all part of the learning

IFN_v6

 

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

To my eyes it is much better.

....and I'll settle for that Steve - thanks

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.
