R1: Montes Haemus has a linear nature to its structure - very straight, almost like a box bottom. The high massif NW of Menelaus appears as part of a short strip along the mare shore.
R2: All 6 lakes (lacus) were easily seen between Montes Haemus and Manilius.
NOTE #1: The west ridge of Manilius was well illuminated, showing ridges on crater wall. 'Ghost crater' to the SE was well filled and joined Boscovich's NW wall.
Observation 2:
The sketch below was drawn April 19, 2021 while observing Manilius (IWLOP #059 - Manilius). What a difference 2 years makes!
