Tubescope: $0-20 Refractor Telescope with camera mount

cults3d

Now you can experience the thrill of being Galileo! Inspired by Cosmos and the recent solar eclipse, this clever refractive telescope lets you explore the wonders of the universe using everyday objects or a mere $20 investment. You have two exciting options: a high-quality handheld telescope that provides an up-close view through its lens, and a camera lens version that works as a powerful telephoto lens with a unique, artistic flair. The lenses used are 40.5mm filter-style close-up lenses that screw onto the end of your camera, giving you a professional-grade look at the world around you. To assemble this incredible telescope, you'll need a few simple materials: a 60mm inner diameter cardboard tube, like the Tu2 Mailing Tube from Australia Post, which needs to be cut down to about 60cm long for the handheld version and 50cm for the camera version. You'll also require a 40.5mm +2 Close-Up filter, easily found on ebay for a low price, and for the handheld version, you'll need an additional +10 Close-Up filter. A set of four filters, including these two, can be purchased on ebay for around $17. Future innovations may include a fully 3D-printed body, improved focusing mechanisms, a kit version that includes everything you need inside the tube, a budget-friendly reflector telescope, rotating mounts for greater stability, and adaptable camera mounts to cater to different photography needs.
