Nice.

Plenty of data there for a 60s exposure. Are you going to take 2 hours worth of 60s exposures and get some good amounts of data?

If we get any more clear nights I will be reducing the ISO to 400 and taking 300s or longer multiple exposures to reduce noise whilst keeping sky background low. Have recently read that Vixen themselves recommend 600s exposure due to f9 ratio to maximise image.
