Description

Object/Date:
C/2020 R4 (ATLAS) @ 2021 April 18, 00:38 UT

Description:
Comet C/2020 R4 (ATLAS) imaged on April 18, 2021, near its maximum brightness. The idea was to do it with a telescope and with a telephoto lens, but the clouds and extreme humidity did not even allow me to open the lid telescope and only take few framing shots with the lens before the mist and dew spoil it all. Finally I decided to process that final framing shot, it does not have the optimal parameters nor exposing time far from it, but at least can be seen the comet in a large field. The brightest star on the left is 95 Herculis with magnitude 5.2 and some reddish clouds begins to show from the nearby Milky Way.
