Vesta
Using the camera by itself on my HEQ5 mount I took photos of Leo's head on 3 nights. I knew that the minor planet Vesta was near opposition in that region. Aligning the resulting images with GRIP I was able to make this 3-frame animation that shows the planet moving in a retrograde direction (the Earth overtaking it at opposition).
