@einfach_orangensaft I had a Bird Jones - worst optics I've ever seen in a telescope. It was cute as a button sitting on my desk, though!

Its like a newtownian just that it has a spherical mirror (cheaper to make) and uses a corrective lens in front of the eyepeace.

MrFappy,

Alright, now explain it.

It’s an inferior telescope with a cheap mirror and built in contacts to make it work

echo,

Awesome ELI5. Now… why is it called that?

keckbug,

As with nearly everything in astronomic optics, it’s named after people associated with its creation. Robert Jones and Thomas Bird are the two in this case. Here’s a thread on Cloudy nights with good info.

mindbleach,

Guy named Bird, guy names Jones.

SkaveRat,

Okay okay

But why were their last names that?
