 This stunning nebulous star cluster in Auriga contains several exciting features not found in most objects of this type. The field of the new Astrograph, some 1.5 degrees wide fits this object very well, and reveals a rich Milkyway star field that surrounds it. The splashy open cluster in the center, which is also the source of ionizing radiation for the nebula is NGC1893. Also known as Mel 33 this 7.5 magnitude object is over 10 arc minutes in size, and contains over 60 cluster members. The beautiful nebula around this cluster is IC410, and is over 25 arcminutes in size. This pink emission nebula contains several dark areas corresponding to dark non illuminated dust clouds in front of the nebula, and two very interesting tadpole like nebular features on the upper right edge (north). These features have leading edge bow shock fronts being pushed back by the intense ultraviolet radiation from the cluster stars.
