Nice image Paul.
5mins exposure in a bortel 9 is crazy. I’ll be lucky if I can do 3mins in a bortel 5-6 and not be over exposed.
Interesting reading the effects the ZWO duoband filter has on galaxies! I was really looking forward to getting one of these to improve my imaging on galaxies in a bottle 5-6 area on my DSLR, but not sure now if that’s what I need
Cheers
Wayne
