Comet

Comets are usually named after their discoverer(s) family name, although with science increasingly being the result of large team efforts, the name of the team or project can be more appropriate so is often used.

Comet C/2022 E3 (ZTF) by George Buckberry – 14th Feb 2023

The latest image of the Green Comet C/2022 E3 (ZTF) that is currently gracing our skies by member George Buckberry. The photo was taken on the 14th February 2023 by George.

”Having spent months climbing up out of Corona Borealis and drifting past the Big and Little Dippers, like a rollercoaster car reaching its highest point, Comet C/2022 E3 ZTF has now gone ‘over the top’ of its path across the northern sky and is falling south, fading in brightness and shrinking in size as it drops towards Taurus.  For northern hemisphere comet chasers and skywatchers E3’s show is almost over.” ref https://www.skyatnightmagazine.com/advice/comet-c-2022-e3-ztf/

So well done George for capturing the Comet, you did well to get it as it’s fading fast!

George has written on the image below of how he acquired the photo and the location of the star Aldebaran to the comet. Aldebaran (Alpha Tauri) is a bright red giant star in the constellation of Taurus.

Member and trustee Martin Crow captured the Comet C/2022 E3 (ZTF) on the morning of the 18th January 2023 at 03:20am. The ion tail of the comet can be seen emerging at around the 2 o’clock angle in the photos.

Comet C/2022 E3 (ZTF) on the 7th Feb 2023 by Honor Wheeler and 8th Feb 2023 by Simon Dawes

Member Honor Wheeler captured the Green Comet C/2022 E3 (ZTF) on the 7th February 2023 using a Canon M6 with a 400mm lens on a Star Adventurer tracking mount. ISO1600, 30″ expsoure.  The comet is centre right in the image in the constellation Auriga.  The bright star Capella is above the comet at the 10 o clock position from the comet and the star Elnath is below the comet between the 6 & 7 o clock position from the comet.

Then just before Moon rise on the 8th February 2023 member Simon Dawes captured this image of the green comet. Details of how Simon acquired the image are included on the photo.

Comet C/2022 E3 (ZTF) by Simon Dawes on 31st Jan 2023

Super image of Comet C/2022 E3 (ZTF) taken by member Simon Dawes with Bessel/Cousins photometric filters and a broadband LPS filter (IDAS LPS D2) then combined to give an RGB image, colour hasn’t been altered. More detail of how Simon acquired his image is on the photo.

C/2022 E3 (ZTF) is a long period comet from the Oort cloud that was discovered by the Zwicky Transient Facility (hence the ZTF in the Comet’s name) on 2 March 2022, using the 1.2-m, f/2.4 Schmidt telescope at Mount Palomar.  It was the 3rd such object discovered in the fifth half-month (A, B, C, D, E) of the year. Thus, 2022 E3 (ZTF).

The comet has a bright green glow around its nucleus due to the effect of sunlight on diatomic carbon and cyanogen.

Comet C/2022 E3 (ZTF)- 29th & 30th Jan 2023 by Jim Burchell

After seeing Honor Wheeler’s image’s of Comet  C/2022 E3 (ZTF) CMHASD member Jim Burchell decided to have a go at trying to image the Comet too.
 
Jim said ”It was rather difficult as the Comet wasn’t very easy to see as there was some high cloud and the Moon was in play.
I was struggling to see the Comet with binoculars so in the end I used my 70 mm telescope but it still wasn’t obvious.
The image below was taken with a Pentax KP camera attached to Altair Astro 70mm ED triplet refactor at ISO 1600 and 15 Second exposure.”
 
The comet is the fuzzy patch in the centre of the image below taken on the 29th Jan 2023 by Jim.
 
The next image below of the Comet was taken by Jim on Monday 30th Jan 2023 using the same setup as the day before.  Again, it was quite difficult to find as the Moon was bright.  The image was then processed by Jim on his phone using an enhanced image tool.

Comet C2022 E3 (ZTF) – 22nd Jan 2023 by Honor Wheeler

CMHASD member Honor has managed to capture Comet C/2022 E3 (ZTF) that is gracing our skies at the moment in a photo back on the 22nd Jan 2023. 

Honor said ”I watched Nick James sky notes on today’s BAA meeting about Comet E3 so decided to look for it. Not that easy to find but it is unmistakable as a faint fuzzy in binoculars. So I took a photo just to prove I wasn’t seeing things. Worth a decent image with a telescope with more time than I had.

The comet is the fuzzy patch centre right in the photo.

Comet C/2019 L3 (ATLAS) by Simon Dawes

A fantastic image of Comet C/2019 L3 (ATLAS) in Gemini taken by Simon Dawes on the 24th April 2022 from Bexleyheath in Kent. 

Simon has included detail about how and when he acquired the image on the photo below showing the comet which is the fuzzy round shape in the centre of the image.

Comet C/2019 L3 (ATLAS) was discovered on the 9th of June 2019 by the ATLAS program.

Comet C/2020 F3 NEOWISE – The Great Comment of 2020

Comet c/2020 F3 Neowise was visible for a couple of weeks in the Northern sky, quite close to the horizon, to say it was spectacular is an understatement and the brightest comet since Hale Bopp visible from the UK.

46P Wirtanen

Comet 46P Wirtanen was billed to be brighter than ever this apparition and when at its brightest it would be passing within 1 degree of M45, however the UK weather conspired against us, some members got images from outside the UK and others from before it reached its brightest, but our visit to Ashdown forest was cancelled due to 100% cloud cover and rain. 

On Thursday 13th December 2018 many members observed the comet at the Dick Chambers Observatory, through binoculars (a very faint fuzzy blob only visible with averted vision) and through the 16″ Peter Hindle telescope.

I’ve been getting some practice with deep sky stacker, not as scary as I thought here is my first attempt using it to stack some images of the comet.

I’ve been lucky to have imaged the comet twice myself, once on Friday 7th & again on Sunday. The seeing has been pretty poor but it was just visible in 10×50 binoculars and looked pretty good in my 72mm refractor and 40mm eyepiece.
