Now, what was the name of that company again...? help!

I've finlly got an acre and a half with good viewing, where I can stick a permanent pier in. I remember there was a U.S. company (in Pennsylvania? I can't remember) that makes 'old fashioned' non-APO, long focal length (as in f12 or f15) refractors... anyone know or recall who it was? If I saw the name I'd know right away.

i'm looking for a planetary scope to supplement my older 8"f6 Dob
