So I tried nebulosity to do the stacking and that appeared to be better. However when I now look at the image the two stars in the posted jpeg they have still merged a bit due to the reduced size and possibly jpeg artifacts.
Ive attached an unprocessed image of NGC1398 and if you look at the double stars there you can see what I mean as there is a clear separation between them which was NOT present after stacking with DSS, so i figured I had lost some detail.
Hope this helps

Hi Allan,
Yes I can see the double stars which does show clarity.
That is strange & I can't think of any DSS setting which would cause that.
Maybe nebulosity is better?

cheers

I have pixinsight as well and I think I'm going to have to bite the bullet and start using it for processing as it really seems to have far more specific routines for astrophotography that the other stacking and processing programs.
