Ta Greg. The 3.6 micron pixels are a good match to the AP130 at F4.5
I think my KAF16803 would have also done a great job on the nebulosity but the star sampling would have been too coarse.

Thanks. The camera field is about 3.5 degrees wide. No exactly a small target.

Not exactly bright either !

....the faint stuff is only hinted at in individual sub exposures.
Looking at other examples on the web seems to confirm that this one needs a system with a high S/N ratio from the get-go, to come out well.
