Lunar crater Langrenus is an awesome sight in a good scope when the air is steady and lots of power can be used. A couple high central peaks can be seen in the below image as well as a number of its terraced walls.

Asteroid 532 Herculina

Currently traveling though through the constellation Ophiuchus is the large, main belt asteroid (225 km in diameter) called Herculina. This one was easy to spot, it matched up with the star field on my notebook exactly.

Image acquired from my backyard in Louisville, CO between 05:10 and 05:42 UT with Celestron Nexstar11 telescope, Meade F3.3 focal reducer, and Astrovid Stellacam II video camera (Gain 9/14, Integrate 128, medium gamma). Sky was clear — first clear night in two weeks, no wind, temperature 68°F, 40% humidity, transparency excellent, turbulence 6/10. Moon quite low in the southeast, didn’t appear to affect images a whole lot.
