Скачать или смотреть A Lava Tube On The Moon: Rima Hadley/ A Heavenly Night To Look At The Moon

In making this video I have used these optical instruments:
Celestron Omni XLT 127 Schmidt-Cassegrain 5 inch telescope.
TMB PLANETARY II 6mm eyepiece.
SVBony Aspheric 10mm and 4mm eyepiece.
Televue Panoptic 24mm 68 Degrees eyepiece.

It was the most stable night that I remember ever seeing. Atmospheric disturbance was absent and I could easily push the magnification to the highest limit. I was able to see for the first time the Rima Hadley near the Hadley Delta mount where Apollo 15 landed. This was the most amazing night I remember. Truly magical or heavenly depending in your beliefs.

Hadley Rille, valley on the Moon, typical of the class of features known as sinuous rilles, which are believed to be ancient lava flow channels. The feature was a primary site of exploration for the Apollo 15 lunar-landing mission.

Named for the 18th-century English inventor John Hadley, the rille is located at approximately 26° N, 3° E, at the southeastern edge of the great lava-filled Imbrium Basin (Mare Imbrium) impact feature. The steep-walled valley, about 1.5 km (0.9 mile) wide and 400 metres (1,300 feet) deep, winds for more than 100 km (60 miles) across the plains of Palus Putredinis along the foot of the Apennine mountain range, a part of the Imbrium Basin’s upthrown ramparts. The rille is easily visible with a telescope from Earth under the right lighting conditions (low-angle morning or evening illumination at the site) and with good seeing (a state of low turbulence in Earth’s atmosphere that allows sharp telescopic images). In July 1971 Apollo 15 astronauts drove their rover to the brink of the curving canyon and photographed possible layering in its eroded walls suggestive of stratified lava beds. Because all lunar features are covered by impact debris and no mission has yet visited the interior subsurface of a rille, the true origin of Hadley Rille and other sinuous rilles remains to be elucidated.
