I have an antique German refracting telescope with an occular lens that took a whack and cracked. Parts for these scopes and replacements are totally unobtanium so I'm hoping to find a shop that could possibly custom make a lens to fit in it. Does anyone know of any custom optics shops? There was a time when I'd have called US Optics and offered them a wad of money but I don't know that they really do that kind of stuff in-house at all anymore. I have the lens pack out of the telescope. It's about 1.5" wide and appears to be a 3-lens pack but as far as I can see only one has a crack.
