R1: Both Gemma Frisius and Goodacre are generally round. Goodacre has its rim interrupted only in the S-SW whereas Gemma Frisius has craters of varying sizes on all of its rims.
R2: Just over the western wall of Gemma Frisius are the craters D, G and H in a line, going from SW to NE. G & H are shallower than D.
C1: To the NW is Poisson with disintegrated crater walls and its unsmooth floor. Crater A and the grouping of U, V, K, Q between it and Gemma Frisius were easily identified.
NOTE: The crater combo of Gemma Frisius, Goodacre and Crater D makes it look like Minnie Mouse with a bow in her hair! However, you might never know it from my sketch!
