The Double Cluster, along with The Heart and Soul Nebulae
This is a 88 minute total exposure through the Nikon 55mm camera lens at f4. This is much better than the 41 frame image of the area from a night with significant transparency issues. December 2010 from the Davis Mountains. See the Heart & Soul Nebula page for telescopic close-ups of those objects.
6x4 minute = 24 minutes exposure from Starry Nights in Wimberley, 12/29/2007. Equipment Canon EOS 20Da (unmodified) ISO 1600, Takahashi TOA 130 (a 5" APO refractor) with flattener, and Astro-Physics AP 900GTO mount. It was early in the evening and I hadn't quite sorted out my guiding, but not too bad. Compare with older film version below.
More info about the double cluster in Perseus here along with an image from a 180mm camera lens. Lots of stars!
Notice the subtle color in some of large red stars.
