The Celestron Inspire 100AZ refractor telescope is now $80 off on Amazon and is a top choice for those without much or any astronomy experience. We've included it in our best telescopes buying guide as the best budget option out there.

You can get the Celestron Inspire 100AZ refractor telescope right now for just $279.64 on Amazon.

This telescope offers an affordable entry point into both stargazing and astrophotography. It's easy to assemble, it comes with a good range of accessories to enhance your experience and it has a large aperture, so plenty of light passes through, allowing targets to appear brighter. In our Celestron Inspire 100AZ review, we found that you get good value for your money and we like it a lot. It isn't the final word in stargazing but, if you're a budding astronomer or you want to try your hand at astrophotography, this is definitely a telescope worth considering, especially at this price point.

Save $80 on what we think is the best budget telescope out there. It offers a great introduction to astrophotography, offers great views of the moon and planets, has a lightweight frame and comes with a range of accessories. Those include a tripod and mount, a folding accessory tray, two eyepieces (10mm and 20mm), a red LED flashlight and more. The 100mm aperture is also a lot for this price point. 


You get plenty of telescope for your money but, what does that look like? Well, the 100mm aperture lends itself well to lunar and planet observations. Its 660mm focal length and lightweight frame mean it's well-designed for beginners and home use to observe even beyond our solar system. 

There are plenty of accessories on offer too but the stand-out is the lens cap which turns into a smartphone holder and allows photos of night sky targets to be taken. It also comes with a quality tripod, two eyepieces (10mm and 20mm) a finder scope, star pointer and red LED flashlight, which illuminates the accessory tray. It also comes with a free download of Starry Night software basic edition.

Key Specs: 100mm aperture, 660mm focal length, a tripod and Alt-azimuth mount is included, two eyepieces (10mm and 20mm), an accessory tray, a red LED flashlight, a smartphone holder, lightweight design, red dot finder, 90-degree erect image diagonal and a free download of Starry Night basic edition astronomy software. 

Consensus: We like this telescope a lot, and this deal even more. If you're a beginner or you're looking to get into astrophotography, this is definitely a deal you should consider. We've not seen this telescope on offer as low as this for quite some time and we think it's the best budget option out there. 

Buy if: You're a beginner or looking to take your first steps into astrophotography. 

Don't buy if: You're looking to splash the cash or you want a seriously high-end telescope.

Alternative models: If this isn't quite right for you we would recommend either the Celestron AstroMaster 70AZ or the Celestron NexStar 4SE both of which we have reviewed and like for their beginner-friendly setup and ease of use.
