The Capes of Sinus Iridum – July 4, 2017

On either end of the Sinus Iridum (Bay of Rainbows) are two capes, or points, called Promontorium Laplace and Promontorium Heraclides that were right near the sun-shadow line on the moon. This area has also been called the “jeweled scimitar” because of its resemblance to the scimitar sword (or sabre).

Tech Specs: Meade 12” LX90, Celestron CGEM-DX mount, ASI290MC, best 2.5k of 5k frames, AutoStakkert! V3.0.14 (x64), FireCapture v2.5.10 x64 and Registax v6. Software used included Sharpcap v2.9 and AutoStakkert! Alpha Version 2.3.0.21. Photographed on July 4, 2017 from Weatherly, Pennsylvania.
