Merope, AT111EDT First Light (Sept. 20, 2012)


Here is a closeup on Merope, one of the Pleiades (also known as Subaru or Seven Sisters, or M45).  The Pleiades are passing through a cloud of dust.  Reflected starlight from the group shines on the dust in blue.  Because the cluster of stars is only about 390-440 light years distant, it appears as a cluster to anyone looking up in a dark sky at the constellation Taurus.

This is first light with an AT111EDT.  I am the second owner, but the scope was well cared-for.  I am excited to fit this scope out for convenient imaging as a replacement for the 6" Newtonian.
