Capture and share your adventures with family and friends: turn your phone into a super-powerful camera and video camera to capture the beauty of the world around you, no matter the distance! This allows you to not only use the magnification of your optical equipment but also zoom in with your phone to further enlarge the image and achieve incredible detail. Perfect for binoculars, monoculars, spotting scopes, and astronomical microscopes: it can be mounted on eyepieces with a diameter between 2.5 and 4.5 cm, which includes most binoculars, monoculars, telescopes, and microscopes. It works best if the eyepiece it is mounted on is on a solid, rigid surface (some eyepieces have rubber cups that can make using the adapter difficult). Universal design compatible with almost all smartphones: includes a laptop stand with a highly extendable width of 5.5 to 9.8 cm (please check that your laptop's width falls within these dimensions). It's compatible with iPhone X/8 Plus/7 Plus/6, Plus/5/5s, Samsung S9/S8/S7/S6, Note 9/8/7/6, Sony, LG, HTC, and many other brands. Extremely easy to use and completely safe for your mobile phone. Its design allows for an easy and secure grip, adapting to both your smartphone and your lenses. Furthermore, it's reinforced with an aluminum plate and a double layer of cotton for added durability.
