I captured a couple of Moon images during the morning of the 30th. The seeing was very averrage but the Moon was directly overhead at the time. I wanted to use the 2x Barlow but was shocked to find a large amount of dust on the lens.
I have no idea how it got there.
I am always careful with putting on the caps and placing them back into the case.
I was just about to make a mosiac but decided not to, maybe another time.
