Jupiter was bright enough to find easily, but not easy to hold still. I attached my Canon T3i to a Dobsonian telescope with a 1200 mm focal length and guided the telescope by hand, repeatedly nudging Jupiter back toward the center of the frame as Earth’s rotation carried it away.
A hand-guided planet


At this focal length, even a small movement sends Jupiter drifting quickly across the view. The process was a simple cycle of patience: center the planet, capture it, gently move the telescope, and begin again. These images are small reminders of that tedious effort—and of how much detail a bright planet can reveal through a backyard telescope.
