C/2020 F3 (NEOWISE) 2020-Jul-17 John Chumack

The Comet was absolutely beautiful to watch through my Fujinon 10x70 Binoculars last Friday night, the Green Coma was very noticeable. Although it has dimmed a little bit it is still visible naked eye because now it sits a bit higher in the western Sky now. We watched from 10:15pm until 11:30pm , until it got too low in the City lights of Fairborn...so I wrapped it up and went home to look at my data. I had city light pollution gradients in the image that made it very difficult to process the light Pollution out without wiping out comet detail,, but I managed to get something of a keeper out of it.

Comet NEOWISE c/2020 F3 on 07-17-2020, captured with Green Coma around Nucleus, and the white Dust Tail and Blue Ion Gas tail, shot from Enon/Fairborn Area, Ohio, at 10:38pm EST (02:38 U.T.)
Canon 6D DSLR Camera, Sigma 150 -600mm lens, set to 150mm at F5.6, on a AVX tracking Mount 7.5 minutes total exposure

ISO 1250, 18 x 25sec stacked in DSS, Nebulosity, Maxim DL, Pixinsight and Adobe CS.

My next capture attempt under dark skies this time will be tonight, I’m hoping for clear skies at my brother-in laws place 90 minutes away from Dayton, before Moonlight starts interferes later this week. The comet is dimming now about mag. , but it is still a beautiful binocular object with a nice tail, bright nucleus and green Coma! It is just below the Bowl of the Big Dipper in the Northwest start looking around 10:15pm EST, the sky should be just dark enough for you to pick it up easily. Find a dark location away from city lights.

Enjoy Comet NEOWISE c/2020 F3 while you can…it won’t be back for some 6,800 years…LOL!

Best Regards,
