what is bird jones?
Its like a newtownian just that it has a spherical mirror (cheaper to make) and uses a corrective lens in front of the eyepeace.
Alright, now explain it.
It’s an inferior telescope with a cheap mirror and built in contacts lenses to make it work
Awesome ELI5. Now… why is it called that?
@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!
