This view of the first-quarter moon was taken on February 25, 1996 through a Celestron CG-11 Schmidt-Cassegrain telescope. Equipped with an f/6.3 focal reducer, the effective focal length was just over 1,760 millimeters. The film used was T-Max 100 and the exposure was 1/125th of a second at f/6.3. The topmost dark grey area is Mare Serenitatis, below which is Mare Tranquillitatis (Sea of Tranquility) the three other lunar seas (from right to left) are; Crisium, Foecunditatis, and Nectaris. Just to the right edge of the moon can be seen Mare Humboldtianum to the upper right, and Mare Marginis and Smyth II at about the 4 o'clock position. Just barely visible at the 6 o'clock position is Mare Australe. The two prominent craters to the upper right of Mare Serentitatis are Aristotle (upper) and Eudoxus (lower). The slightly darker grey area above them is Mare Frigoris. The two craters directly above Mare Nectaris are Theophilus (with the "bullseye" in the center) and Cryillus. At the time this image was taken, the moon was about 47% illuminated (as seen from Earth) and was at a distance of 395,537 kilometers. (According to the program Voyager II.)
