Description

The ultimate telescope for the novice to intermediate astronomer, the Inspire 100AZ features the largest aperture in the Inspire family line and its short tube offers a wider field of view perfectly suited for larger, fainter deep sky objects. Packed with features never seen before on entry level telescopes, Inspire features fully coated glass optics, a solid altazimuth mount with a unique asymmetrical design, a sturdy steel tripod with integrated fold-up accessory tray, an integrated smartphone adapter, built-in red LED flashlight, large projected reticle finder scope, erect image optics, and a focus micrometer for easily returning to the same focus point. The Inspire has the easiest setup of any telescope in its class. Simply pop open the tripod legs, turn the lock knob on the accessory tray, and attach the telescope tube to the base using the quick release dovetail mount. You are now ready to observe! The lens cap has an integrated smartphone adapter built into it. Place your smartphone against the rubberized friction surface on the outside of the cap so your camera is viewing through the imaging port. Secure the smartphone using the two adjustable bungee cords. The inside of the lens cap has a fitting that secures to your eyepiece using two set screws. Voila! You are now ready to take high power images through the telescope. The mount has a red LED flashlight built-in. Turn the flashlight on to illuminate your accessory tray with a soft red glow. The flashlight can easily be removed from the mount to provide red light where you need it most. The focus micrometer is a numbered scale that indicates the focuser’s position. It allows quick return to a specific focus point for specific targets such as a bird nest, infinity focus, etc.

  • Great telescope!
Style: telescopes
Bought as a Christmas gift and just used. Was able to see the moon very well. Kids love it. Sight included needs to be calibrated with the telescope. I didn’t get the chance but still was able to spot the moon without it. Haven’t tried the included software yet

  • Nice telescope
Style: telescopes
I’m a casual backyard astronomer and I bought this to leave out near my back door to check out a few planets or the moon.I like the way this is built. It looks and feels very solid. It’s a good looking telescope. It’s obviously not that James Webb, but for the money, I think it’s a good deal and I enjoy it. Also, the finder scope works well although it’s a little confusing to figure out how to use it for the first time. ... show more

  • Worth the price
Style: telescopes
This is a recent purchase, so I might adjust the score later (that's why I gave it a "4", for now). I have used it several times and found everything is working just fine. The product came well-packed and without damage. There is a problem with one of the focus adjust dials, but I think it is operator-error... maybe. Overall, however, I am pleased. If someone is looking for movie-style images of the planets, they will be disappointed. Yet, it does deliver what it claims. This is a great introductory product for Astronomy. I would recommend, as I have done, that you purchase additional lenses for more detailed viewing. As it comes, the optics are good quality and set-up is very easy. I definitely recommend this telescope. ... show more

  • Great for a beginner!
Style: telescopes
I have never owned a telescope. This was so easy to set up. I did order a Celestron moon filter kit due to the brightness of the moon. Received it just in time for the Parade of Planets. Now, the planets just look like bright stars through it, although we are pretty sure we saw the rings of Saturn. I do recommend for general moon watching. Or even wildlife/landscape. I am a review reader. And I usually start with the bad lol. BUT, sometimes, the low star ratings are meh. I recommend this for the money, if looking at the moon and some small constellations is what you prefer. ... show more

  • Great telescope!
Style: telescopes
We got this for our son who loves to look at the stars. We’ve gotten telescopes before and couldn’t really see very well so we didn’t want to make the same mistake but also didn’t want to spend a ton of money. Well, this one was a little more expensive but it’s totally worth it!! He’s already been looking through it and it’s so easy to see the stars and planets. So glad we got this one! ... show more

Excellent and Works Great. You are able to see the details of the moon - the mountains, craters and soil color.

  • Frustrating
Style: telescopes
Not a good telescope. It’s very difficult to center an object in the field of view because it doesn’t turn easily.
