Comet Leonard A1 - Close up with the 10 inch
in the Morning sky
12/4/21

 
 This
            comet is getting much too large now for the 10 inch, with its
            1 meter of focal length! A beautiful teal colored coma and a
            tawny tail charecterizes this celestial splendor, now approching
            7th magnitude. Getting low in the morning sky, but still over
            the observatory wall at 4:30 am.
