You've been asking for long focal length lenses. This one is 4000mm! Unused, coated positive meniscus lens with a diameter of 42.4mm.
One of our customers used this lens to make a 17th century sytle long refractor. 15 feet long! He used shipping tubes from McMaster and indicated that he gets good images. Thanks for sharing that info, Ray. |
