Article says - >>When Mr. Leonard found the comet's "image", it was an exceedingly faint object of magnitude 19.<<
Repeat - Mr. Leonard found the comet's "image"!
I think, it's not easy to find anything at mag 19 with a conventional small telescope or never mind with a binocular.
Maybe the article refers to this Czech guy that he found the comet first visually with his bino?
Far as I know, a comet can be found by multiple people, but the very first who reports it is the one who can claim it?

if that discovery is visual or in an image. It doesn't even require
the discoverer to be a human being. When comet discoveries are
reported by multiple people at nearly the same time, the comet carries multiple names (e.g. Hale-Bopp).
This object was discovered by exactly one person, long before it was detectable visually.

long before any amateur ever gets a chance. That's why there are quite a
few PANSTARRS discovered comets (they are really looking for NEOs).
https://en.wikipedia.org/wiki/Pan-STARRS#/media/File:Neo-chart.png
Comet discovery is a by-product.
The odd one sneaking in from too close to the sun for the automated
systems still gets spotted by an amateur first but it is a rarity now.
Time was when mostly Japanese amateurs with huge binoculars and a near photographic memory of the night sky would bag them first. I'm not fully
up to date with amateur comet discoveries but the most recent that I can
find was last year namely C/2020 A2 (Iwamoto) and C/2021 O1 (Nishimura):
https://www.nao.ac.jp/en/news/topics/2020/20200114-comet.html
https://www.minorplanetcenter.net/mpec/K21/K21O47.html
The discovery image is quite remarkable. I'm sure I would not have
spotted it - I presume he was blinking against a reference frame!
A small number of extremely keen Japanese observers still do it: https://www.nao.ac.jp/new-info/comet.html (mostly in Japanese)
(names of observers are in English too)

I got up at 5 this morning on the off chance that the sky would be clear and I could ride my bike to a nearby darker sky site and try to find it with binoculars. It was foggy.
Too much political discussion. close this thread.

Be interesting to see how it looks near Venus after it rounds the Sun.
It will be in evening twilight, so it may not be any better unless it brightens quite a bit.

56 does, however, divide by 8. It equals 8 times 7.
So the exit pupil of the binocular is exactly 7mm;
But for an older person's eye pupil only opens up to 4-5 mm max .
So 2-3 mm of light is wasted?
