Thanks for the advice Greg. There is a bit of coma in the scope as it is a f5 Newt. I would like to get an MPCC.
I will be out again tonight with a higher iso (weather permitting). I am used to imaging right in the centre of Sydney and I find if I push the iso higher than 400 it washes the whole image out and vignetting becomes a huge problem.
I spend a lot of time drift aligning to make sure it is right but I find that getting focus is the biggest issue.
