Comet C/2020 Atlas M3 in Orion
with 10" f/3.9 Astrograph
Uploaded 11/10/20

 

            
This 8th magnitude comet
            is currently just west of the belt stars of Orion. While no obvious
            tail is present, it does have a very nice green / teal color
            and hints of an inner fan tail like structure. This shot was
            50 minutes worth of 2 minute subs with the 10 inch f/3.9 Orion
            Astrograph.

            
The first image is a
            normal stretch, the second is highly processed to reveal two
            tails, pointing to the left a dust on top and gas below.
