The moon is 8.7 days past new, waxing gibbous, and lighting up the sky. The faux-daylight blue is very strong in photographs. I used three lenses tonight: Olympus 75mm f/1.8, Canon FD 300mm f/4 L, and an Astro-Tech AT80EDT f/6 refractor (480 mm focal length).

Just for fun, while I had the telescope mounted (on a ZWO AM3), I snapped some pictures of a couple star clusters. The bright moonlight is not ideal. However, the measured sky brightness was sqml=20.28, which is darker than a moonless night in Santa Fe. Both exposures: 30 sec, unguided.
