Description
Description: Elger
(IAU Directions) MACLEAR.--A conspicuous ring-plain about 16 miles in diameter. The dark floor includes, according to Madler, a delicate central hill which Schmidt does not show. Neison, however, saw a faint greyish mark, and an undoubted peak has been subsequently recorded. I have not succeeded in seeing any detail within the border, which in shape resembles a triangle with curved sides.

Ranger 6
Southeast of Maclear, near four unnamed dome-like formations (north-northwest of the large dome Arago Alpha), is (or should be) the impact location of Ranger 6, which was an unsuccessful attempt to make close-up photographs of the moon while the probe descended toward the lunar surface.
The exact coordinates of Ranger 6's impact location are: 9°24' North/ 21°30' East.
Note that chart 35 of Antonin Rukl's Atlas of the Moon doesn't show the location of Ranger 6.

Nomenclature
- Sir Thomas Maclear (January 17, 1794–July 14, 1879) was an Irish-born South African astronomer. Dr. Maclear had a keen interest in amateur astronomy, and would begin a long association with the Royal Astronomical Society, to which he would be named a Fellow. In 1833 he was named as royal astronomer at the Cape of Good Hope, and arrived there to take up his new duties in 1834. He worked with John Herschel until 1834, performing a survey of the southern sky. He continued to perform important astronomical observations for several decades.
