Description

Object/Date:

C/2020 R4 (ATLAS) @ 2021 May 4, 21:33 UT

Description:

Comet C/2020 R4 (ATLAS) imaged on May 4, 2021, ten days after closest approach to Earth, with a brightness at magnitude 11 its greenish coma measures 8 minutes in angular size and shows an ionic tail with 13 minutes in length. Due to fast comet movement on the celestial background, I had to compose the image by adding a stack on the stars and another on the comet, images taken from home suburban sky.
