Comet Hartley 2 and the Eskimo Nebula
in the Morning sky
10/12/23

 
 Now
            at its peak brightness, the comet passed the Eskimo nebula (NGC2392)
            in Gemini yesterday morning, closest approach was after sunrise
            for us here in Arizona but I shot until 5am when twilight broke.
            This shot is all 90 minutes of exposures stacked onto that last
            2 min sub, and represents the appearance at that time. The small
            planetary can be seen as a teal colored disk to the upper right
            of the comets head.
