After the sun had set I also took a few frames of the Moon. The scope used for both of these frames was the "new-to-me" TEC 140, which gives a nice image scale with the nearly 1,000mm focal length. Even though I wasn't tracking, the thousandth of a second exposure needed for the moon froze the Earth's rotation and Moon's apparent motion. The image is cropped and kept near the maximum image size so the fine details in the craters can be seen.
The rest of the evening was uneventful. We spent time shooting wide-angle tracked shots, as well as exposures through the TEC 140 mounted piggyback on the telescope we had at our disposal. We also had classroom sessions on data manipulations once the images were collected. We took a night lunch break, and while the students went back up to the telescope, I headed back to Tucson about 11pm. You always have to be on the lookout for wildlife on the drive down the mountain at night. Over the years I've seen everything from mountain lions to bobcats, skunks to ringtail cats. Usually over the Summer snakes can be seen on the asphalt as the pavement retains heat into the evening, but haven't spotted any on my trips for ages.
