PICTURE OF THE DAY

Sinus Iridum

Sinus Iridum

The imager sent in these comments: “This is what the Virtual Moon Atlas calls an ‘exceptional formation,’ and I do agree. When you see it at this lighting there’s always a slight gasp at the glittering Montes Jura and the two Promentoria at the entrance of the Bay of Rainbows. Unfortunately, due to the curvature of the Moon, I don’t think you could see both if you were standing between them. I like how Helicon and Le Verrier look in this image. The smallest features I could make out in this seeing measure just under 2 kilometers.” (8-inch Telescope Engineering Company TEC-8 Maksutov-Cassegrain reflector at f/20, Celestron Skyris 445M CCD camera, best 500 of 1,500 images taken, stacked, taken November 14, 2013, at 2h25m UT)
