Sinus Iridum
Hi all,
Sinus Iridum from a patch of excellent seeing Tuesday Morning. At 235 km diameter from promontory to promontory, the sinus (bay or recess) looks like a perfect bite out of the Jura mountains in which it intrudes.
The poetic relationship between Sinus Iridum - the Bay of Rainbows - and its parent body of "water", Mare Imbrium - the Sea of Rain - is hard to miss. The bay is a remnant crater flooded when an impactor crashed into what is now Mare Imbrium and sent a flood of lava into the crater burying the southern portion.
Celestron Edge HD 14" and ZWO 178 MM camera. Approx 3200 frames with best 3% stacked in Autostakkert!3 and sharpened in Registax. Bintel Red Filter.
