This gem is adjacent to M35 and has always fascinated me. Even at this
I was unable to completely resolve the background glow on this ridiculously
open cluster. I was able to detect clearly a resolved triangle of stars,
perhaps only
a dozen or so, with a granular background glow at the verge of fully resolving
This is a small cluster, only 5 arc minutes across.

M35 nearby is huge, about 30 arc minutes, and filled with very bright, but
varied in brightness stars that look like diamonds on diamonds. Round, but
in structure so that I could not recognize a definite pattern.
