Tycho Rays   Leave a comment

A clear night, 94% illuminated Moon.  First use of a ZWO ASI294 color camera.  Easy to shoot; after two hours I collected 342 gig and ran out of disk space.  This is the best 50 of a thousand frames stacked and processed to bring out the rays.  25% size of original.

To honor the 50th anniversary of Apollo 8 and the iconic photo of Earthrise over the Moon, two of the craters in the imager were renamed.  Here is a model of  Anders Earthrise, formerly Pasteur T.

1:500,000 scale, representing 120km on the Moon or 75 miles.  Model is of Hard Maple lumber 9.25″ on a side.

William Anders and the rest of the crew of Apollo 8, Frank Borman and James Lovell had craters named for them after their flight around the Moon.  Here is a model of Anders crater, same size and same scale:
