Jupiter and two moons, 5:45pm November 22, 2009. Zhumell 10″ f/5 dobsonian with monochrome Scorpion camera. Jupiter drifts across field of view; no tracking. One alignment on Jupiter smeared the moons. 300 of 410 stacked. The moons were invisible when saving as jpeg, so I selected all but Jupiter and pegged the brightness (+150) in Photoshop to make them visible.
