23 Day Moon in early morning~

Went in for a first look with the 10mm at 5:21 am. Unfortunately, probably about 3/4 hour too late for best viewing due to oncoming sunrise. Also, a band of thin pink clouds decided to go across the Moon causing some interference. Visibility is dropping rapidly. 

However, the big star of the show near center of the FOV is Copernicus with Reinhold and Lansberg off to the side. The Sea of Rainbows is nicely visible to the north, with a dramatic series of craters to the south along the Terminator which I identified later as Clavius flanked by Longomontanus and Wilhelm northward vs. Scheiner and Blancanus southward.

The Sun cometh~

Shut it down at 5:56 as it was becoming useless with the approaching sunrise. Time to shift to early morning front porch viewing with the AR 102 if I want to do any lunar observing plus check out the current dance of the planets to the east. Moonrise will be even later tomorrow if the skies and body cooperate. As I put the scope back into home position and shut it down the first rays of Sun illuminated the roof of the Ob just as I was about to close it, as if to say goodby.

No time to get any images of the 23 Day Moon, would have had to start at least 1/2 earlier.
