The above shows my GSO 10" RC with just over an hours worth of 5 min subs with a qhy10 camera, taken with a near full moon from the near CBD of Brisvegas.
To be honest I don't know of a more severe test than this. I'd love a dark site but mine is heavily light polluted but this is what can be done when imaging time is at a premium.
