The weather tonight was a lot worse than NOAA or any of my other weather resources had predicted. Peter had brought the TelePort but never bothered to set it up. We did a little naked-eye observing but mainly talked since it has been a couple of weeks since we have seen each other..

CommentsSaw it naked-eye at 2030 EDT.
I can’t detect any phase in the binocular.
Later in the evening when Venus dropped into more atmosphere it lit up a ring of haze around it. This effect is very prohounced in the binocular but visible to the naked eye.

CommentsSaturn was the last of the planets to be seen naked-eye.
I thought I got an indication of rings in the binocular but it doesn’t seem to me that I should be seeing them in an 8x hand-held instrument.
