    Haydes Star Cluster imaged at the 90mm observatory in Harleysville, PA on November 17, 2009 at 11:37 PM. From the perspective of observers on Earth, the Hyades Cluster appears in the constellation Taurus, where its brightest stars form a "V" shape along with the still brighter red giant Aldebaran. However, Aldebaran is completely unrelated to the Hyades, as it is located much closer to Earth (hence its apparent brightness) and merely happens to lie along the same line of sight. Details: Pentax *ist DS, Tamron AF70-300mm f/4-5.6 LD MACRO set to 70mm f/4 ISO 800. 10, 7.5 second images stacked for a total of 1min, 15 sec image.
