Telescopes are in Nikon Incorporated catalogs in 1955 alongside the Nikon S2. Two were listed, a 2 inch and a 2 1/2 inch. They were likely available much earlier, since the first Nikon sales representative for Nikon Incorporated, Al Levin, sold Nikon microscopes during the time he was taking delivery on Nikon synced "M" cameras.

Glenn says the telescope performs really well on moon and planets and isn't affected by atmospherics as is usual with larger apertures. He believes the telescope is a simple achro doublet F/15.

The setup below was used on a day Glenn was observing sun spots, using the Nikon sun projector. Glenn has made an adapter to use standard 1.25" TeleVue Plossl eyepieces. (Televue Plossls are the finest eyepieces of the 50° apparent field of view class. Because of noticeably less astigmatism and lateral color at field's edge, they deliver very sharp images.)

Typical beautiful Nikon wooden case, similar to those provided with all the long Nikon rangefinder lenses.

Thanks to Glenn for sharing his telescope with the NHS!
