It's a well framed and produced image with a lovely, spooky colour palette.

There does appear though to be an obvious joining seam visible 1/3 of the way in from the LHS.

Might be worth a revisit, as it's got the makings of a very good image

Thanks Andy, I noticed that too, was my first attempt using the Photometric Mosaic script in Pixinsight instead of the usual Star Alignment process so will definitely be working on version 2 of the image.

Great work Jim

I have used merge mosaic in PI and it works very well.

Tutorial here: https://www.youtube.com/watch?v=H2r3ZYqCaP8

Lot of stuffing around

Thanks Peter, I've used that method in the past, this time I used image solver on each tile, then mosaic scripts and I've just finished playing around with the photometric mosaic script and I think the result is a bit better now. I also made two versions. first one is HaHSO and the second is LHSO with L created by integrating SHO together, think there's a bit more detail in this one now.

I did a single sub of S2 yesterday before the clouds came in and I packed up.
I didn't see the same detail as in Ha in the single sub.

Colours are a perfect blend of Hubble pallette with another level of a subtle cast.
Well done..
