Comet C/2020 H5 (Robinson) is a rather interesting comet despite what one sees in the images. The comet is magnitude 18.1 in the images and 806 million miles from Earth, so this comet if it came closer to the Earth and Sun would be a very bright comet. Unfortunately, the comet was at perihelion in it's orbit this past November 2020 when it was 867 million miles from the Sun. It made it's close approach to Earth this past April 2021 when it was 792 million miles from Earth and only brightened up to magnitude 18. So as with most comets we are left to wonder what if, what if it had an orbit that took it into the inner Solar System, maybe next time, unfortunately it has an orbit of about 34,000 years. As with most faint comets the images are not much to see, especially since the comet was at a declination of -32 degrees low on the southern horizon just above my neighbors bright lights and out in Saturn's neighborhood.
