(Hard to believe Kohoutek was almost 40 years ago!)

But if it is a black rock flying though space the reflection will be minimumal. Just seems worse than a needle in a haystack.

It's not a black rock, even though black rocks also reflect some light depending upon the surface; it's a comet, a dirty snowball and the coma developed, making it more visible than an asteroid of similar size as the comet's nucleus.
