Comet Brewington C/154P 
December 27, 2013

 

            
 This faint
            11th magnitude object rides high in the evening sky inside the
            Great Square of Pegasus. It is moving slowly against the background
            stars, and is in a field of faint galaxies. The two seen here
            are 15th magnitude, and the limiting magnitude is around 19 because
            of the poor seeing. (normally its 20.5 in an hour exposure)

            
This is an LRGB
            with the L data spanning about 45 minutes. The comet shows a
            nice teal color.
