Belts and zones on Jupiter. Identified moons by name through use of computer program. All moons in same plane in their orbit. Rings visible. Rings at an angle. Crescent phase. Craters, shadowed part of moon. Inverted image. Red star. Point of light. Comments blue Double star with two colors Two points of light – stars in Big Dipper Galaxy – edge on spiral Globular cluster. Red-orange star Greenish donut Blur - galaxy rings Open cluster Moons different position from previous night. crescent Very defined crater, larger crescent.
