The Way I See It > Looking over the lunar landscape

Limiting Mag:	4.5
Antoniadi:	III
Weather:	50°F, calm, high thin clouds
Constellations:	---
Equipment:	114mm reflector, 20x70 binoculars, 15mm TV Plössl, 13mm TV Plössl, 2.5x Barlow

The high-thin cirrus clouds that provided a spectacular sunset quickly dissipated and left somewhat clear skies with only an occasional thin cloud passing by. I setup the binoculars and the 114mm telescope to continue working on the Astronomical League Lunar club checklist.

863	01:09	Albategnius	LF	---
		Colongitude: 15°.3, Sunrise Terminator: 164°.7 E In 20x70 binoculars, Albategnius appears as a large crater with wide sloping walls. The crater Klein is visible on the western wall of the crater. A central peak is discernible in the center of the crater.
864	01:13	Hipparchus	LF	---
		Colongitude: 15°.4, Sunrise Terminator: 164°.6 E In 20x70 binoculars, Hipparchus appears as a large, deformed, shallow crater. The crater Horrocks lies in the northeastern region of the crater floor.
865	01:18	Aristillus	LF	---
		Colongitude: 15°.4, Sunrise Terminator: 164°.6 E In 20x70 binoculars, Aristillus appears as a small, round, deep crater in the eastern region of Mare Imbrium. The smaller crater Autolycus lies to the south and the larger crater Archimedes lies to the northwest.
866	01:27	Autolycus	LF	---
		In 20x70 binoculars, Autolycus appears as a small, round, deep crater in the eastern region of Mare Imbrium. A slightly large crater Aristillus lies to the north and the much larger crater Archimedes lies to the west.
867	01:27	Archimedes	LF	---
		Colongitude: 15°.5, Sunrise Terminator: 164°.5 E In 20x70 binoculars, Archimedes appears as a large, round, crater with steep walls. The crater lies in the eastern region of Mare Imbrium. The smaller craters Autolycus and Aristillus lie to the east and southeast respectfully.
868	01:32	Clavius	LF	---
		Colongitude: 15°.6, Sunrise Terminator: 164°.4 E In 20x70 binoculars, Clavius appears as an oval-shaped crater with wide sloping walls lying within a heavily tormented area near the southern pole. The walls of crater Clavius are disturbed by two craters, Rutherford to the south and Porter to the north. Two small craterlets are discernible in the floor of the crater.
869	01:38	Tycho	LF	---
		Colongitude: 15°.7, Sunrise Terminator: 164°.3 E In 20x70 binoculars, Tycho appears as a deep crater near the southern pole in a heavily tormented area. The shadow of the crater wall crosses near the center of the crater floor giving the crater a “C” shape.
870	01:43	Maurolycus	LF	---
		Colongitude: 15°.7, Sunrise Terminator: 164°.3 E In 20x70 binoculars, Maurolycus appears as a large, steep walled crater lying on the eastern edge of a heavily tormented area near the southern pole. The wall of Maurolycus is disturbed by a small crater on the northwestern side. A prominent ray (from Tycho) extends from the crater in the eastward direction.
871	01:50	Plato	LF	---
		Colongitude: 15°.8, Sunrise Terminator: 164°.2 E In 20x70 binoculars, Plato appears as an oval, steep-walled crater lying at the western end of the Montes Alpes mountain chain. The floor of the crater is extremely dark and appears fvery flat and unmarked.
872	01:55	Ptolemaeus	LF	---
		Colongitude: 15°.9, Sunrise Terminator: 164°.1 E In 20x70 binoculars, Ptolemaeus appears as a large, round, steep-walled crater with a flat, undisturbed floor. Ptolemaeus is the largest and northernmost crater of a three crater chain including the craters Alphonsus and Arzachel.
873	02:01	Alphonsus	LF	---
		Colongitude: 15°.9, Sunrise Terminator: 164°.1 E In 20x70 binoculars, Alphonus appears as a large, round, steep-walled crater with a central peak in the center of the crater. Alphonsus is the center crater in a three crater chain including the craters Ptolemaeus to the north and Arzachel to the south.
874	02:05	Arzachel	LF	---
		Colongitude: 16°.0, Sunrise Terminator: 164°.0 E In 20x70 binoculars, Arzachel appears as a round crater with wide sloping walls and a large central peak. Arzachel is the southernmost crater in a three crater chain that includes Ptolemaeus and Alphonsus.
875	02:11	Walter	LF	---
		Colongitude: 16°.1, Sunrise Terminator: 163°.9 E In 20x70 binoculars, Walter appears as a round, sloping walled crater lying in a heavily tormented area near the southern pole. A small group of craterlets lies just east of the crater center.
876	02:16	Maginus	LF	---
		Colongitude: 16°.1, Sunrise Terminator: 163°.9 E In 20x70 binoculars, Maginus appears as an oval-shaped crater with wide, sloping walls lying southeast of crater Clavius in a heavily cratered and tormented area near the southern pole. The floor of the crater appears flat and unmarked.
877	02:22	Eratosthenes	LF	---
		Colongitude: 16°.2, Sunrise Terminator: 163°.8 E In 20x70 binoculars, Eratosthenes appears as a round, deep, steep-walled crater lying east of the crater Copernicus. Eratosthenes lies on the western end of an outcropping of Montes Apenninus, which seems to wrap around the crater and extend southward.
