Capture and share your adventures with family and friends – Turn your cell phone into a SUPER-powerful camera and camcorder to capture the beauty of the world around you. No matter how far away you are! This allows you to not only use the magnification of your optical equipment but also zoom with your phone to further enlarge the image and achieve incredible detail.

Perfect for binoculars, monoculars, terrestrial telescopes and astronomy, as well as 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 eyecups around the eyepiece which can make it difficult to use the adapter).

Universal design that fits almost all smartphones – It has a phone holder whose width is highly extendable: from 5.5 to 9.8 cm (please check that the width of your phone is within these dimensions). It can be used with iPhone X/8 Plus/7 Plus/6, Plus/5/5s, Samsung Galaxy, S9/S8/S7/S6, Note 9/8/7/6, Sony, LG, HTC, and many more brands.

Extremely easy to use - Completely safe for your cell phone - We designed it to be easy and secure to grip, both for adapting to your smartphone and for your optical equipment. It is also reinforced with an aluminum plate and a double layer of cotton to improve its durability.
