Astrofoto: Komet ZTF – C/2022 E3 – 02/23
Eines meiner Ergebnisse des Kometen ZTF C/2022 E3 im Februar 2022. Mir gefällt die leuchtend grüne Farbe dieser Version.

C/2022 E3 (ZTF)

C/2022 E3 (ZTF) is a long-period comet from the Oort cloud that was discovered by the Zwicky Transient Facility (ZTF) on March 2, 2022. The comet has a bright green glow around its nucleus, due to the effect of sunlight on diatomic carbon and cyanogen. It’s closest approach to Earth was on February 1, 2023, at a distance of 0.28 AU (42 million km; 26 million mi).

Open Cluster NGC 1647 in Taurus and Comet C/2022 E3 (ZTF)

I know I am kind of late to the party. But in my defense: When I checked where the comet was in the sky when I first heard about it, it was in the north, and my house was blocking the view. I didn't realize that it will be coming around to the south where I can image it.

Here is the location and future path of comet C/2022 E3 (ZTF) in the night sky, as seen from the U.S. on Feb 13 around 9:30 p.m. mountain time, facing south.

Comet C/2022 E3 (ZTF) is dimming rapidly, currently at magnitude > 7.
Current distance from earth = 0.483 au = 72.25 million km.

Here is a gorgeous composite image of the departing comet C/2022 E3 (ZTF) along with planet Mars taken two nights ago.

The broad white dust tail and the long narrow blue ion tail are clearly visible. The coma shines brightly in green color at 518 nm wavelength, emitted by C2 (dicarbon) atoms.

In the foreground is the Matterhorn, a mountain in the Italian Alps with a picturesque peak.

Where to see comet C/2022 E3 (ZTF) in the night sky from central U.S. tonight. The comet will be visible near the Pleiades cluster. Mars will be visible within 2 degrees of the comet. See map below.
Magnitude > 6, hence binoculars or a telescope will be needed.

Nice shot of Comet C/2022 E3 (ZTF) along with planet Mars, taken by Michael Jäger yesterday from Austria.
Comet C/2022 E3 (ZTF) is still sporting its two tails (dust and ion) as it races away from the Sun to back home in the Oort cloud.

#PastelSketches of the #FullMoon + #comet C/2022 E3 #ZTF at the eyepiece of my #Helios 102mm refractor fitted with zoom eyepiece using black paper + #StabiloCarbOthello #PastelPencils #AstronomySketching #LunarSketching #C2022E3

Finally got a view of #comet C/2022E3 (ZTF)! Only had a few minutes before the clouds rolled in (again).
Still much processing to do though.
This is 27 x 3 second exposures with a Nikon Z50 with a 300mm lens on a tripod (no star tracker).
I *really* need a better setup for #astrophotography.

This is my best photo of Comet C/2022 E3. This green comet passed Earth for the first time in 50,000 years. It was last visible in the night sky during the Stone Age. 48,000 b.c.e.

But we have had gray skies forever (of course right?).

Nikon D750, 510mm 80ED OTA on tracking mount. If you want more details, just ask.

#C2022E3?

Nein, nur ein Flugzeug. 😂

Started the day well before Dawn comet-spotting with the eldest. 💫✨

3hr #StarTrails from 31st Jan that shows the trail of #comet C/2022 E3 (ZTF) crossing the stars. Colour boosted to bring out the green. Gaps are due to cloud. Taken from Oxfordshire, UK with a #Canon1100D + 18mm kit lens. 30sec shots at ISO-800, heavily cropped #C2022E3
#ZTF

Overnight 31st Jan '23 I imaged #Comet C/2022 E3 (ZTF) with a #Canon1100D + kit lens for 9 hours from Oxfordshire, UK. You can see the tiny comet moving around Polaris as the Earth rotates, but also see how fast it was moving against the background stars. The video is too big for a direct upload, but it's on You Tube here: https://youtu.be/y3N2Q7yjTzk #C2022E3 #ZTF

Long orbital period is long.

Also, since it seems to have gotten lost in some of the news coverage:

#C2022E3 has an orbital period of about 50,000 years.

It is very much not a "once-in-50,000-years" event. There are tens of thousands of comets like it.

Tonight, a green comet named C/2022 E3 (Z.T.F.) will be visible in the night sky as it traverses our part of the solar system. The last time this ball of dust…

Zanosi sie na to, ze i dzisiaj, i jutro w nocy bedzie pochmurno, czyli nici z szukania #kometa #c2022e3
Nie, zeby mialo ja byc jakos bardzo dobrze widac golym okiem 😆

Tra oggi e domani avremo il picco e il momento migliore per osservare e fotografare la cometa C/2022 E3.

In questo video vi spiego come fare:

Da kommt einmal in 50.000 Jahren ein #Komet vorbei und dann ist es bewölkt.

Diese Regierung ist wirklich zu gar nichts zu gebrauchen! #C2022E3

#RedSPMN LAS IMÁGENES DE GRAN CAMPO TAMBIÉN CAPTAN EL COMETA #C2022E3 #ZTF. En este hilo pondremos ejemplos de imágenes apiladas bajo estudio en el @iSpaceSci que permiten seguir astrométrica y fotométricamente el cometa entre capturas continuas del cielo 📹Ramón López

And here it is! Comet ‘C/2022 E3 (ZTF)’!

This image is a stack of 9 images, each taken with 30s of exposure. I configured the stacking software (Lynkeos) to track the comet instead of the stars in the background, hence they look blurred while the comet looks stationary.

Taken with a Nikon Z 6ii, AF-P Nikkor 70-300mm (@300mm), ISO 640, 30s, ƒ/5.6. All mounted on a Sky-Watcher EQM 35 WiFi go-to azimuthal mount.

Woah. So… I thought I had messed up my stacking logic, but turns out I used such long exposures that I captured the comet's movement!
