Trio of equal-sized craters.

Origin: Impact   Diameter: 64 km, 71 km, 73 km   Rukl: 2    Type: CS

Objects: Bettinus, Kircher, Segner, Zucchius
Others Identified: Bailly, Wilson, Tycho

Location: Home
Date: 2019-03-18
Time: 8:22 PM AST
Equipment: 6" Sky-Watcher Dobsonian
Eyepiece: 10 mm eyepiece

Magnification: x110 
Seeing: Very Good (2)
Transparency: Very Good (2)

RI: Seeing the chain of 4 craters caught my eye. Zucchius, Bettinus and Kircher were easily found adjacent to Bailly.
R2: Segner looked to share a common rim or ridge with Zucchius, and that Wilson shared a common rim or ridge with Kircher. Segner and Wilson had very faint peaks on their crater walls compared to the other craters.

Note: I first saw these 3 craters (Zucchius, Bettinus and Kircher) two years earlier when they were on the lunar terminator. Refer to the RASC Explore the Moon (Telescope) - July 31, 2017 for details.
