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

Perfect for binoculars, monoculars, spotting scopes, astronomical telescopes, and 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 adjustable: 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 other brands.

Extremely easy to use - Completely safe for your mobile phone - We designed it to be simple and secure to grip, both for adjusting 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.
