Hi All

I am trying to recall the name of, and thus find the website of, a company that used to make very long achromat doublets telescopes, I think in Pennsylvania.  Their website made a big deal about their QC and they sold all sorts of accessories.  They made up to 8 inch lenses, if I recall, at up to f/15. 

Any ideas?

Thanks

Robert Howe

I found it!  D&G.  Thanks anyways.
