More moon and Jupiter
The moon is almost full but I decided to setup again tonight in front and see if I could snag a sidewalk visitor or two. I did meet Floyd Smith, a neighbor and first year resident of GGG out walking his dog. It took three tries to marginally align the ETX, not a good night. It wanted to use Vega which was behind a palm tree, and after I started on my second try, the power went off. I finally took the timer of off my outlet and at least stopped that little aggravation. The third time was better: I got Vega ok but missed Fomalhout but found Jupiter ok as well as the Moon. All four moons were on the same side but IO and Europa were overlapped too close and I could not split them. Calisto was barely visible just to the south of a line between Jupiter and the other three moons. Ganymede and the two overlapped moons were plenty bright and easily seen. I was able to make out one cloud band on Jupiter just fine with the yellow filter. Moving on to the Moon, there wasn't much of a terminator but Cardanius and it's companion crater Krafft were obvious, very clear and high contrast. Grimaldi, the dark circular plain, was obvious as were two craters just to the north: Hevelius and Covalarius. The yellow filter kept the brightness down enough so that it wasn't painful to look at the moon but it wasn't as comfortable as first quarter.
