Description

Done under less than optimal conditions: very warm night, with moon, from suburban skies, barlowed at f/12.5, with canon 450D mono. My motivation was to try a new autoguiding configuration, to achieve 20 minute subs with no flexure.

NEW REVISION: added 3.5 hours of data in a cool night. Interestingly, calibrated 10-mintue subs at 3°C sensor temp, contributed the same SNR as 20-minute subs at 10°C.
