Note:
Seeing 7 out of 10. Very nice morning, moderate dew. Had to undew the secondary mirror.
For the first time, Solis Lacus actually looked like Solis Lacus! Plenty of detail around the center and surrounding areas. Bright area on South Polar Cap, along with a notch and the bald spot. Very faint North Polar Hood. Blue filter showed almost no detail. 20-inch stopped down to 17-inch. Casual glance for moons, but didn't see
