There few galaxies in Leo that are
as detailed and display outer structure like this one. This 9.7
magnitude object spans a huge 13 arcminutes across, and in the
same field we can find many distant 16th magnitude galaxies as
well. The brightest of these is UGC5086, directly above the galaxy
near the top of the frame. This 16th magnitude dwarf is .9 mins
in size. A peculiar object is to the left (south) of the galaxy,
a small disk of light known as MAC0932+2122, another 16th magnitude
galaxy only .4 mins in size and of unknown classification.
Seeing was terrible
this night, the wind was blowing hard all day and the sky was
turbulent but totally clear. So what do you do with a brand new
camera under these conditions? You shoot the sky!
