Analog Sky Space Binoculars
This kit lets you view the night sky not with one eye, but two, for sharper, brighter, and more comfortable stargazing. It can be ordered as plans only, optics and hardware only, as a BYO 3D printing kit, or a kit with pre-printed parts. In 2022, they’ll also open source the build plans. There’s also a large, assembled model, but it’s much pricier.
