Last night I observed and sketched two double stars as well as M72, M73, and an un-named (as far as I know) small asterism similar to M73.
The session actually began with a sighting of the International Space Station gliding across the sky. The ISS appeared to be somewhat brighter than Jupiter -- a rather brilliant, white, moving light in the sky. Of course, as the ISS entered the earth's shadow it rapidly dimmed.
The seeing was 'good' -- a '6' on the modified Pickering Scale. I used 477x for the seeing check.
My NELM was 6.5.
Observations and sketches were all made at 135x, though other magnifications were used at times.
