Accessories Included

The Inspire 90 comes with two eyepieces (20 mm and 10 mm), a 90° erect image diagonal, an integrated smartphone adaptor, a finderscope, and a red LED flashlight.  The two eyepieces offer different magnifications to view your intended object. The erect image diagonal allows for right-side-up viewing ideal for terrestrial subjects but can also be used for celestial objects. The Star Pointer finderscope will help you quickly centre an object in your eyepiece for easier observing. Illuminate your accessory tray with the built-in red LED flashlight. The flashlight can easily be removed from the mount to provide red light where you need it most.

Smartphone Adaptor

Image celestial or terrestrial objects with this smartphone adaptor! With its light, rigid frame, this accessory allows you to connect any smartphone to any telescope eyepiece with an outside diameter of 45 mm or smaller. The additional magnification provided by the eyepiece allows your phone to capture great images of the Moon, planets, and terrestrial targets like birds and wildlife.  This smartphone adaptor installs easily by clamping over the top of an eyepiece.  The smartphone is held in position with the help of bungee cords that securely lock your phone in place. While the vast majority of smartphones can be used with the case on, some very large and/or bulky phone cases (such as folio style cases) may need to be removed for the phone to fit in the adaptor.
