of a line of three open clusters in Auriga, and by far the best
of the three. This rich open cluster spans 25 arc minutes, occupying
nearly this full field here, and is bright at a whopping magnitude
5.6. 150 stars are listed as cluster members in Megastar. The
color variations of the stellar members is striking. With a background
of hordes of blue super giants setting the stage, a score of
yellow to orange K type super giants super impose themselves
all across the clusters face.
No other deep sky
objects appear in this field to about 18th magnitude and the
reason is clear when you look at the colors of the faint stars
- all very yellow or reds from obscuring Milky Way dust. We are
in fact right in the path of the "Zone of Avoidance"
of galaxies in this field.
