I am not doing astro work but moonlight shots which can freeze the stars in 25 seconds UWA down to 10 seconds at longer FL. Its a contest between time ISO and aperature. The sweet spot would be f4, ISO1600 and less than 20 seconds depending on focal length.
I am more interested in the landscape itself with the stars just a secondary element. I have to use a lot of NR now and it looks ok at web size but does not print.
I also need an ungraded live view for manual focusing.
