 There are few objects in the sky as exciting as the dual rich open clusters, known as the Double Cluster in Perseus. In both binoculars and telescope, they stir the intellect into contemplations of cosmic wonder. Besides being very rich, a sprinkling of very orange stars lies over this group, making for a dramatic portrait. This image is a pair of 5 minute exposures stacked in Picture Window Pro, using multiply - this is the same as stacking two negatives in the enlarger. I cant emphasize enough how having the larger field of view is appreciated over the usual ST8i shots.
