More Mooning

by David North


I did a bit of full mooning last night as well. That was one of the smaller terminators I've seen, but it was definitely there...

The sky wasn't very steady, and I could only manage to get two of the craters on Plato, even through the 12.5-inch. Just for ducks, I tried for some rilles but didn't have much luck. Nevertheless there was quite a bit of detail in Gassendi; I'm just not sure if it was rilles or ridges.

Got my first detailed look at Mars just at the end. Was able to make out the polar cap and Hellas, and the disk was clearly bifurcated though I couldn't be sure exactly what features were causing it. One of them seemed almost certainly Syrtis Major...
