It was very hard to find him and in the end I did it with just 70mm on my camera and lens. Quite a challenge for sure. I now not perfect but for 70mm not to bad :-)

C/2022 E3 (ZTF) is a long-period comet from the Oort cloud that was discovered by the Zwicky Transient Facility (ZTF) on 2 March 2022.[1] The comet has a bright green glow around its nucleus, due to the effect of sunlight on diatomic carbon and cyanogen.[6][5]

 

The comet's systematic designation starts with C to indicate that it is not a periodic comet, and "2022 E3" means that it was the third comet to be discovered in the first half of March 2022.[5]

 

The comet nucleus was estimated to be about a kilometre in size, rotating every 8.7 hours.[7][8] Its tails of dust and gas extended for millions of kilometres and, during January 2022, a third anti-tail was visible.[9]

 

The comet reached its perihelion on 12 January 2023, at a distance of 1.11 AU (166 million km; 103 million mi), and the closest approach to Earth was on 1 February 2023, at a distance of 0.28 AU (42 million km; 26 million mi). The comet reached magnitude 5 and is visible with the naked eye under moonless dark skies.[10][11][12][13] (Wikipedia)
