Transit of Mercury

9 05 2016

The day started out a bit cool, with me running around the house trying to find a good spot to set up. Started on the front sidewalk, but soon moved to the backyard. Spent most of the day observing, punctuated with frisbee breaks. I wish I had sketched more carefully to capture the effects of Earth-Sun rotation.

Backyard. 130-mm reflector w/white light filter, Coronado PST.
