Comet Giacombini Zinner
in the Morning sky
September 7, 2018

 
 This
            comet is still quite faint in the 80mm guide scope with a low
            power eyepiece, but is very nice for imaging at a variety of
            focal lengths. Here, the 10" f/3.9 Orion astrograph was
            used for an hour of exposure integration.
