Celestron 100 mm Inspire Refractor Telescope


The Inspire 100AZ refractor, the lightest model in the Inspire series, is a high quality telescope for those with beginner to intermediate levels of experience. The 100 mm Inspire is easy to carry and store, and is equipped with features heretofore unseen on entry level telescopes. These include fully coated glass optics, a sturdy alt-azimuth mount with a special asymmetrical design, a solid adjustable steel tripod with folding accessory tray, built-in smartphone adapter, integrated red LED flashlight, StarPointer Pro finderscope, erect image optics, and a focus micrometer for simple reversal to the same focus point.

The Celestron Inspire has the most straightforward assembly of any telescope of its kind. Just pop open the tripod legs, twist the accessory tray's lock knob, and affix the optical tube to the base with the quick release dovetail mount. That's it. You're now ready to explore the universe!

The Inspire 100AZ has a lens cap with a built-in smartphone adapter. Set your device up against the rubberized friction surface on the exterior of the lens cap so that the camera is observing via the imaging port. Two adjustable bungee cords help safeguard your smartphone. The interior of the lens cap features a fitting that fastens to your eyepiece using two set screws. This is all you need to take high power images through your Celestron Inspire 100AZ!

The mount features an integrated red LED flashlight that when turned on will highlight your accessory tray with a soft red glow. Furthermore, the flashlight can easily be taken from the mount if you desire red light elsewhere.

The focus micrometer is a numbered scale that demonstrates the position of the focuser. It provides fast return to a particular focus point for specific targets like a bird's nest, infinity focus, etc.
