Due to Saturn’s large axial tilt, its moons transit the planet infrequently — only during ring plane crossings, which occur twice during the planet’s 29.5-year orbit. The evening of Sept. 20/21 was the last chance to see the entire shadow of Titan, Saturn’s largest moon, cross the planet’s disk until 2038. This photographer captured the event with a 9-inch scope and planetary camera, taking 75 minutes of video frames and stacking the top 25 percent clearest frames.
