Taken with the CDK12.5 and the PW 0.66 reducer from our backyard over 3 nights through semi-cloudy skies.
The AP1100GTO performed admirably, tracking the target unguided through the clouds and allowing data to be captured throughout the night. The subs(exposures) blocked by clouds were then deleted.
The QHY268m with its very low sensitivity and very high quantum efficiency is a perfect candidate for the task.
