 With
            the wind howling in the trees all night long, I knew the seeing
            would be poor, and yes - 1.5 /5 was a mess. But the moon was
            a very thin crescent, and at 9 am this morning was over half
            way up in the east as the Sun rose over the tallest trees. While
            lacking in sharp detail, look again for those "Black Craters",
            which are filled in with shadow and only seen during very slim
            crescent phases. Observing guides dont even mention them.
