Observing the Moon with binoculars

Last night I had a short observing session of the 15-day-old Moon with the 15x80 binoculars and the SkyWindow. I concentrated on the large and obvious features that where visible. I could identify a lot of Mare on the nearly full Moon: Mare Crisium, Nectaris (with the crater Fracastorius), Fecundatis, Tranquillitatis, Serenetatis, Imbrium, Frigoris, Nubium, Humorum, Cognitum, Vaporum and Oceanus Procellarum.

Other features that where visible where Sinus Iridum, the 145 mile wide Crater Grimaldi with its dark floor (on of the darkest features visible), the craters Tycho, Copernicus and Kepler with its bright crater rays and Plato with its dark, lava flooded floor. There where two craters that stood out from the rest (extremely bright): Tycho and Aristarchus. especially Aristarchus stood out as a bright white beacon.

What I also found very striking while observing with the binoculars was the Imbrium basin. I never noticed the outline through the telescope, but with the binoculars it seemed to be very obvious.

At the end of my 1-hour lunar session I shot this image with the Coolpix 4500 handheld at the binocular. The image was taken at 21:32 UT. The settings of the camera where: shutter 1/125s, aperture f5.8 and ISO 100.
