Cassiopeia is the upside down chair above and
left of center. The green fuzz ball in the upper right
corner is the Andromeda Galaxy (M31) and the nearly full
Moon causes an unwelcome glow coming from the upper
right hand corner. Perseus is just below center, and the
comet is circled. Note the Pleiades near the lower right
hand corner. Two radio towers are partially seen in the
lower left hand corner. |
