THE BAY OF RAINBOWS!

''The Bay of Rainbows or Sinus Iridum is one of the most majestic features on the Moon. Measuring 242 x 157 miles it is also one of the largest crater like formations on the visible surface. The surface of the bay falls by almost 2000 feet from the level of the Mare Imbrium. Nestled in the Jura mountains’ surrounding the bay is the crater Bianchini (23-miles in diameter), and beyond that Harpalus (23-miles), in between is the crater Foucault at 14-miles in diameter. Below the crater Mairan are two very interesting features. Gruithuisen Beta and Gamma are two genuine volcanic domes, each about twelve miles across. Gamma is the highest rising to 3900 feet above the mare, and it also has a summit crater of about 900 metres diameter on its top. The image was taken on February 28th 2007 and is a stack of 380 frames in Registax. 90mm ETX and Toucam provided the capture.''
