Cant get these images to work with Linear Fit

[blinky]

 

I've got 3 stacked Ha images that I want to turn into a mosaic.  I have stacked and Mure Denoised them and the next step I thought, would be to linear fit before turning into a mosaic.... When I try and run linear fit on them I get the results below, I choose the Horsehead frame as the ref, the drag linear fit on to the other 2 images.  The bottom images are the results of this once I then apply the same stretch as the Horsehead frame - any ideas?  And any ideas how to sort???

TBH I have no idea but any chance you can allow me to download the 3 images and I would like to give it a go in PI.
Mosaics are on my list of things to try this year if I get the chance so would love a go at it and if I get anywhere ai will certainly let you know 🙂

There certainly isnt anything wrong with the data as it stacks in APP as a mosaic just fine.  I'm transitioning to PI, just havent made that leap yet.

Cool!  Dunnon what Im doing wrong, any chance I could PM you my email and you could look to transfer the file to me as a fits so I can process it further?

Yeah dunno why I didn't think of that!

I need to restock the horsehead without the plane and I also have 10s subs to go in the horsehead as well.

Cheers, Only just seen this as I forgot to follow the thread, I will have a go in PI later, but looks like you have made some progress with some help from @tooth_dr

Yep, got it all sorted, really pleased with it, shame I will probably need to wait till next winter to get O3 and Sii but this is looking not too bad!  I managed to do it myself in Pixinsight and also added in 10s subs of  Orion nebula as well as a restack without the place which was messing up the flame/horsehead region a little.

That's a lovely image, and of targets I wanted to do a mosaic of, maybe end of this year I might get round to it.

I am aware I completely overworked this version, but I find it quite amazing how much data this 32bit image contains and I tried to bring it to the fore. I hope you do not mind the play.

Wonderous structure and details - like a cosmic painting...
