Hey Tony ,
Surface brightness is the key I believe
I've done some not so "bright PN's since and my set up is still giving , in my estimation , a reasonable result. Faint low brightness Galaxies not so much . As long as you get enough stars to stack. I have been upping the ISO as there were a few times it just wouldn't and I had to can the data. Cheers
