Description

Taking advantage of two nights of clear skies, combined with good seeing, the subject's height above the horizon, and the absence of wind, I collected a few hours of signal.

With good leveling and horizontal calibration, there were very few discarded frames.
I always prefer to make sure of autofocus by applying the Bahtinov mask, and then the lens hood before the telescope performs image calibration.
