Description

1st of 3 September objects.

These September evenings were particularly dark at 21.5 SQM with an unusual Marine layer over San Diego this time of the year. 15-minute luminance subs hovered around 2.1" FWHM measured using CCDWare. In general, a very dark and steady period. Color shot with a 10 mph wind, but the direct drive L600 kept to within +/- 1".
