2009 A 2nd night of observing in a single week, after months of little or none at all.
\nWe took Sky Quality Meter readings with both our own standard version and the RASC Responsible Lighting SQM-L boxes. I took some more images with the canon camera, tweaked the allsky camera timings, updated the SBIG camera drivers (some of those had not been updated in 7 years!).
\nSBIG Drivers:
\nsbigudrv.dll was v4.60.32 is now v4.61B3
\nsbigudrv.sys was v4.06 is now v4.07
\nsbiguldr.sys remains the same at 2.46 and
\nsbigusbe.sys remains the same at v1.1
\nThere does not seem to be anything notable to comment on, except that they did in fact work.
\nWe tracked down Comet C2006\/W3 Christensen, just of Sagitta. It is listed in Starry Night Pro v3.1 as mag 11.9 but it must have been brighter as it was just on the edge of averted vision visibility in the 20cm scope.
\nNo images unfortunately, just a defocused blob in the right place.<\/p>\n

\nSagittarius in the south (64 sec) zoomed in a little. Star trails become evident.<\/p>\n
