I dropped my sweetie off at the Catalina Observatory with some students for a weekend education program held there at the 61 inch telescope. This view of Jupiter was made with eyepiece projection from the 61 inch (1.54-m) Kuiper Telescope on Mt. Bigelow north of Tucson. The exposure of 1/200 seconds. you can clearly see the red spot, a giant storm that has persisted on Jupiter since it was first recognized in early telescopes. It was difficult to focus the image while hand-holding the camera to the eyepiece. Best image quality was hit and miss as you tried to align the camera with the eyepiece in the dark while focusing the camera lens or telescope.
