Location: 41.8 S 14.0 E    Origin: Impact     Size: 114 km (Maurolycus), 82 km (Barocius)     Rukl: 66     Type: CC

Objects: Maurolycus, Barocius, Brieslak, Clairaut, Buch, Büsching

Observation 1:
Location: Home
Date: 2019-06-10
Time: 10:20 PM ADT

Equipment: 10" Meade SCT
Eyepiece: Explore Scientific 12 mm eyepiece with 92° FOV + x2 Barlow

Magnification: x416
Seeing: Very Good (4)
Transparency: Very Good (4)  

R1: Both craters showed terraced walls. Especially visible were SE Maurolycus and Barocius that appeared steeper the the other walls. Maurolycus had a central peak plus at least 4 very small craters within.

C1: The craters Breislak and Clairaut were towards the south. Breislak had terraced walls and an uneven floor. Clairaut had 2 craters within it. Buch and Büsching appeared very shallow compared to Maurolycus.

NOTE: With effort, I was also able to identify Maurolycus G, L, A, J, M, F and D. Also identified Barocius B and C easily.


Observation 2:
Location: Home
Date: 2021-04-19 ADT
Time: sometime between 7:00 PM - 10:30 PM ADT
Temperature: 12° C - 8° C
Equipment: 10" Meade SCT
Eyepiece: Explore Scientific 4.7mm with 82° FOV + x2 Barlow
Magnification: x1060
Seeing: not recorded
Transparency: not recorded 

Maurolycus: Very easily could see the main and secondary central peak. At least 4 craters on the floor and 2 with direct impact on the rim. Ridging or slumping of the east wall was evident.

Breislak: Its NE rim showed at least 4 craters on its wall or just inside on the floor. There were 2 craters on its SE rim and a small one in the NW.

Clairaut:  More definitive this session. Two large craters on its floor. Three small craters on the outside of its SW rim. Crater A had a direct impact on its SE rim while Crater E hit just on the edge of the NW rim.
