One for all you TeleVue fans

[E621Keith]

They don't need to do comparison with competitions in an article, but they shouldn't give Televue credit for other people's innovation. High quality 70deg wide field eyepiece with 20mm eye relief existed long before Delos even appeared on TV's drawing board. By failing to mention existence of the people who came up this this class of eyepiece and those who made it popular, it is effectively giving TV credits for doing it.

The introduction section went like:

1. Most eyepiece works well at F10, but cheap eyepiece show defects below F6

2. Ortho and plossl are great, but they have narrow FOV and ER.

3. Nowadays you don't need to compromise. TV introduced a new eyepiece that combines all these nice features, 20mm ER and 72deg AFOV ...

The article didn't explicitly say TV came up with this eyepiece class, but it did give the impression TV did.

I don't have any problem with the rest of the article, just the intro.
