Thanks Jase, Mike, Paul and Gary for your comments and help.
I now have a Bart mask so I'm looking forward to using that for focusing. I'm not convinced I got it spot on for this shot.
I'm happy how my mount is tracking / guiding, but I don't think I can go beyond 10min subs due to light pollution. I'm using an IDAS filter to cut the pollution as much as possible.
Would I be correct in assuming that when the subs have a very washed out background they are too long? Once I hit 10min subs the background density reads about 80 out of 256, is there any point going longer from my location?
Cheers,
David.
