Experimenting with my setup for taking pics through my scope with an iPhone XS Max, and my success of the night was Mare Crisium aka the Sea of Crises.
Adapting from Wikipedia:
- A lunar mare NE of the Sea of Tranquility, it is about 556 km / 345 miles in diameter.
- It has a very flat floor, with a ring of wrinkle ridges (dorsa) toward its outer boundaries.
- The crater Picard is located just to the east of Yerkes (both at 8:00 on a clock dial), and northwest of Picard are the craters Peirce and Swift (at 10:00 on a clock dial).
- Like most of the other maria on the Moon, Mare Crisium was named by Giovanni Riccioli, whose 1651 nomenclature system has become standardized.
The image was taken June 6, 2019 from Ottawa, Canada in my backyard using a Celestron NexStar 8SE, iPhone XS Max in NexYZ adapter, NightCap software, f/2.4 lens, ISO 15, 1/125s, single frame, modified in Windows Photos (flipped, straightened 8 degrees, vanilla filter for contrast, brightened).
