Twilight Dome Fun

Here are a few images from goofing around yesterday evening with the NOFS 61-inch telescope, dome, and twilight. Images were taken with a Canon G3 X at ISO 125 on 2019-02-07 MST. Clicking the “full-resolution image” link (or just the image itself) opens the image in a new browser tab. Ordering is reverse-chronological because I like the 7:02pm image best.
