 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.
