Photographic Map
(This map is based on an Earth-based photograph that has been computer-corrected to zero libration. The vertical white lines indicate the left and right boundaries of the Rükl rectangle)
Background image source
Named Features
- Airy swirl (an unofficial name for the peculiar Reiner Gamma type formation west of Airy at the flat region unofficially called the Loro basin on the Rand McNally moonmap).
- Aliacensis (Van Langren's Elisabethae Palat. Fil.) (J.Hewelcke's Mons Antilibanus, together with the IAU's Werner) (note: Aliacensis is the pronounced crater at the lower right corner of Chart 55).
- Alpetragius (Van Langren's Mazarinii, J.Hewelcke's Mons Phoenix) (note: this crater's pronounced central peak is often called Egg-in-a-Nest).
- Alphonsus (Van Langren's Ferdinandi III Imp. Rom.) (note: this is the pronounced crater slightly rightward of the upper left corner of Chart 55).
- Arzachel (Van Langren's Annae Reg. Fran., J.Hewelcke's Mons Cragus).
- Arzachel Gamma (the central peak of Arzachel) (see Chart 82 in the Times Atlas of the Moon).
- Blanchinus (Van Langren's Fromi).
- Celenorum Tumulus (J.Hewelcke's disallowed name for the La Caille-Vogel chain).
- Delaunay
- Donati
- Dublier (a disallowed name from H.P.Wilkins for Alphonsus D).
- Faye
- La Caille
- Loro Basin (an informal name for the flat region west-southwest of Airy, contains a less-known swirl formation, the name Loro Basin was printed on the Rand McNally moonmap). I see on SLC-map C6 the circle-shaped remains of what seems to be an ancient crater about halfway between Airy and Arzachel. This could be the same formation as Rand Mc.Nally's Loro basin.
- Lunar X (an informal name for a popular clair-obscur phenomenon).
- Millas (a disallowed name from H.P.Wilkins for Parrot C) (J.Hewelcke's Mons Cadmus).
- Mini Egg-in-a-Nest (a nickname from D.Caes for Thebit L with its central peak).
- Parrot
- Purbach (Van Langren's Christierni IV Reg. Daniae, J.Hewelcke's Mons Libanus).
- Regiomontanus (Van Langren's Christinae Reg. Suec., J.Hewelcke's Mons Libanus).
- Rimae Arzachel
- Schupmann (P.Fauth's disallowed name for Hell B at the lower left corner of Chart 55).
- Terra Dignitatis (Van Langren's disallowed name for the whole of Chart 55).
- Terra Fertilitatis (Riccioli's discontinued name for the region south of Arzachel) (thus depicted on the map in the Dutch book Op Ontdekking in het Maanland by A.J.M.Wanders, 1949).
- Terra Sanitatis (Riccioli's discontinued name for the region north of Thebit/Donati (thus depicted on the map in the Dutch book Op Ontdekking in het Maanland by A.J.M.Wanders, 1949).
- Thebit (Van Langren's Rantsovii).
- Vallis Parrot (an unofficial name from D.Caes for the valley-like groove at the south-southeastern part of Parrot, which is part of the Imbrium radial sculpture).
- Vallis Parrot C (an unofficial name from D.Caes for the short valley between Parrot C and La Caille GA, which is part of the Imbrium radial sculpture).
- Werner (Van Langren's Eychstadi) (J.Hewelcke's Mons Antilibanus, together with the IAU's Aliacensis).
- Werner Alpha (the central peak of Werner) (see Chart 83 in the Times Atlas of the Moon).
- Werner D (a tiny high-albedo craterlet on the northern part of Werner's rim, supposed to show brightness changes throughout the lunar day) (see also Lassell D, Linne, and Posidonius Gamma).
- Werner-Airy Basin (unofficial name) (see also Rukl Zone 56).

Many central peaks
- There's a curious abundance of craters with central peaks at the Arzachel-La Caille-Parrot region. It is remarkable to see so many central peaks up here, such as those at the curved row of craters Argelander, Airy, Donati, Faye, and also in craters Parrot C, Arzachel, and Alpetragius (to the west).
