If you would like to be notified whenever we have fresh stock, email email@example.com and ask to be added to our mailing list for "secondhand optics" (binoculars, telescopes, microscopes etc). We will then send you an email three or four times per year inviting you to look at this page. Each email will give you the option to un-subscribe.
Telescopes tend to be long; sometimes they are made shorter by putting a bump (prism) in the middle (some say, 'spotting scopes'); when they are small enough to hold and use in one hand they tend to be called monoculars; tiny telescopes made of several sections ('draws') were made in the 18th and 19th Centuries, the technical term for these is 'spyglasses'.
