looks Ok to me in the jpeg image.

You have the same odd artifact around the edge that will need cropping off LHS and bottom.

I was told what caused it but cannot remember now.

try a 0   zero second exp if it will let you

 

I took some flats when I did the ha and you have guessed it they make things worse again .

I am using the H9 cos that was what is set at the mo with the OAG and it saves me 2x binning

No idea what you 2 are on about but I suggest salt, vinegar and brown sauce for the chip.

 

Very nice picture by the way, looks fantastic to me, can't wait to see the finished thing.
