Last Night's Jupiter sketch.
Seeing: Antoniadi III Last night was cold and windy, and the fast moving clouds were also playing havoc with my Jupiter observations. Tal1 did a good job of dampening down the vibrations of the gusting wind - even at X169 the image was pretty well vibration free. I decided to make a brief sketch and then get back to the warm fire as quickly as possible to draw up my results. Here is the finished sketch in pencil.
