Our take on the Celestron Inspire 100AZ 66x100

The Inspire 100AZ is a 100mm refractor on a manual alt-azimuth mount, aimed at beginners who want a simple, no-fuss first telescope. Its standout feature is the smartphone dock built into the mount, which lets you shoot through the eyepiece without a separate adapter. The 100mm aperture gathers noticeably more light than the common 70mm starter scopes, so globular clusters and the brighter nebulae hold up better, though chromatic fringing on the Moon and planets is visible. Owners like the tool-free setup and the red-dot finder; experienced users find the bundled eyepieces and the lightweight tripod the weak points.

Cons

What reviewers say

Beginners generally rate the Inspire 100AZ well for easy setup and the phone dock, and the 100mm aperture is a real step up from 70mm kits. More experienced owners criticise the color fringing, the flimsy tripod and the weak bundled eyepieces.

Questions and answers

Is the Inspire 100AZ good for a beginner?
Yes. It assembles without tools, needs no collimation and includes a finder and eyepieces, so a first session is straightforward. Expect to upgrade the eyepieces later.
Can I see planets and galaxies with it?
The Moon, Jupiter and Saturn show detail, and bright deep-sky objects like the Orion Nebula and some star clusters are visible. Faint galaxies need dark skies and patience.
Does it need batteries?
Only the red-dot finder uses a battery, which is included. The mount is fully manual, so there is no motor or tracking to power.
Can I attach a camera or phone?
The mount has a built-in smartphone dock for shooting through the eyepiece. A dedicated astronomy camera or DSLR needs a separate adapter.
How does it compare with the 70mm starter scopes?
The 100mm lens collects roughly twice the light of a 70mm, so clusters and nebulae are brighter. It is also larger and heavier, so it is less of a grab-and-go scope.
What is in the box?
The optical tube, alt-azimuth mount and tripod, a red-dot finder, a star diagonal, two eyepieces and a smartphone dock. An accessory tray is included.
