Lunar #88: Peary
Peary is a crater of 75 km diameter close to the lunar North Pole. It can be observed only at very favaourable libration in latitude. To find it, follow the sequence from Scoresby via Challis and Main to locate the larger Byrd (94 km). Peary is the next one north. If you have the map by Antonín Rükl available on which the Lunar 100 have been added with red numbered markers, then you will find that this is one of two entries missing.
Refer to Wood's list (2004a and 2012a) and to his notes (cf. Hardwick 2013a). Compare your observation with the Atlas virtuel de la Lune (Chevalley and Legrand 2012a). In this atlas, at high resolution, in general, consider a photographic texture like the LRO WAC mosaic as well as the synthesised topography of the LOLA Kaguya Shade texture. For regions near the lunar limb, changing from the foreshortened Earthlings' perspective to the vertical view down on the Moon can be instructive.
