M100 was large and with somewhat low surface brightness, but easy at
111X. It showed as face on with a definite brightening of the central
regions at 166X. Outer edges seemed to fade for some reason. At 166X
NGC432 appeared as a small stellar "smudge". Actually I am unsure if
seen. I could not locate IC783,NGC 4328, and 4322 at any magnification
even though they should have been within the C-8's grasp.
