With the Inspire 100AZ, it’s easy to see Saturn’s rings, the Cassini Division inside them, and a few cloud bands on the planet itself, though they aren’t very colorful and just look like symmetrical stripes. A few of Saturn’s moons can also be seen, with Titan being the brightest among them. Rhea, Tethys, and Dione are easy to spot; Enceladus and Iapetus are tougher.

Galaxies, nebulaes, star clusters and large parts of the messier should be viewable although there may be issues showing accurate colours with some stars. Following the theme of this telescope, the Celestron Inspire 100AZ Refractor can see a little bit of everything. This is because it has solid optics that are well suited for a variety of different stargazing types. That’s a lot of added extras. I particularly like the Finderscope and StarPointer Pro which make observing so much easier and successful. You’ll be able to precisely locate and fix on your target – something that is difficult to do without this component. Verdict That's because its bearings are a little stiff and imprecise, though with a little practice it’s possible to get good views of the star clusters and galaxies. However, the darker the sky, the better.Being a refractor, it can also get great views of the moon, Jupiter, Mars, Saturn, and other objects within the solar system. A 100mm refractor has the capability to do a surprising amount of stuff. The Inspire 100AZ works like a 114mm or so reflector because it doesn’t have any mirror surfaces that reflect light or anything in the middle that gets in the way. You won’t quite be able to resolve globular star clusters or see much in the way of detail in galaxies, even under dark skies, but the 100AZ can still show you the entirety of the Messier catalog and a wealth of detail on the Moon and planets. Celestron provide a comprehensive set of accessories to use with this scope. The following come included in the box: The extra magnification of your eyepiece will help you to take great photos of whatever it is you are observing, whether that is the the Moon and the Planets or anything on the ground if you are using it for terrestrial purposes (e.g. Wildlife). To fit the adapter, all you need to do is fit it on top of one of the eyepieces (instructions on how to do this are included in the box) and attaching the bungee cords. Your smartphone will then be held firmly in position. Despite that, it will not get as clear and sharp views of deep sky objects as a dedicated reflector geared for deep space viewing. It will also lag behind more focused refractors that excel at getting views of high contrast things like the rings of Saturn. Again, it can do everything well but nothing spectacularly.

The Inspire, by Celestron, is a refractor telescope that bills itself as the perfect fit for the beginner stargazer. It has some nice upgrades; also, it looks sharp and comes with some accessories in the box to keep you busy for a while. It is quite a bit more expensive than those junky box store endcap telescopes but also a lot nicer.The Inspire 100AZ includes two standard, interchangeable 1.25” eyepieces: a 20mm Kellner providing 33x magnification and a 10mm Kellner providing 66x magnification. These are all-plastic in construction (the lenses are, thankfully, glass) and will work well. You’ll probably want additional eyepieces to get the most out of this telescope, however—both at the low power end for wide-field vistas of deep-sky objects and at the high power end for viewing the Moon and planets. The object may be in the telescope’s eyepiece, but it could be too dim to see. This is more likely when observing faint deep sky objects from light polluted or moonlit skies. In this case, we recommend going to darker skies or waiting until a New Moon to get a better view. Lastly, and most controversially, is the lens cap/smartphone adapter. Celestron’s design here is straight up bizarre. By removing a small plug from the cap and removing the eyecup from your desired eyepiece, then camping the assembly together with a small plastic screw, you can slide your smartphone between the elastic straps on the lens cap and use it as a crude smartphone “digiscoping” adapter. However, this has a few caveats. For one, it won’t fit any aftermarket eyepieces that don’t have a flush barrel and removable eyecup. Secondly, it obstructs a portion of your smartphone’s screen, which can make setting your phone camera’s focus and other features somewhat difficult. Last but not least, you are entrusting your smartphone’s safety to some cheap elastic straps and a singular nylon thumb screw. So keep that in mind.
