The Owl Nebula, M97
Click on image to enlarge
Click on image to enlarge
M97 is a small planetary
nebula in Ursa Major.
Often the "common" terms
given to many deep sky
objects are difficult to
fathom, but I think most
viewers will agree that the
"Owl" is a name well suited
to this object. The "eyes" of
the Owl are actually visible
to those peering through a
telescope (8" or larger) in a
dark sky location -- those
living in light polluted areas
may still be able to see this
feature with the aid of a
nebula filter. M97 is
estimated to be 6000 years
old -- a mere baby!
