Overview
The StarSense Explorer LT 80AZ is a solid entry-level refractor that solves one of the biggest frustrations for new astronomers: finding things. Rather than relying on guesswork or finicky star-hopping, the included StarSense dock lets your phone analyze real star patterns overhead to calculate exactly where the telescope is pointed. Follow the on-screen arrows, and when the bullseye goes green, your target is in the eyepiece.
It genuinely works. The optics are a 80mm f/11.3 achromatic refractor, a design that performs well on the Moon, Jupiter, Saturn, and double stars. At this aperture and focal length, you will see Saturn's rings, Jupiter's cloud bands, and lunar craters in satisfying detail. Deep-sky objects like the Orion Nebula and Andromeda are visible but will appear modest, as physics limits what 80mm can gather.
The alt-azimuth mount is lightweight and stable enough for the tube, and the slow-motion altitude control helps you track objects smoothly. At around $185, this is a reasonable investment for a beginner who wants guidance built in, not just a printed star chart and a wish.

Key Features
- The StarSense app uses actual sky recognition, not just gyroscopes, making object location far more reliable than standard phone-based planetarium apps
- The 80mm achromat delivers crisp views of the Moon, planetary detail on Jupiter and Saturn, and recognizable deep-sky objects like the Orion Nebula
- The app generates a curated target list based on your location and time, removing the guesswork of deciding what to observe on a given night
- At 4.17kg total, the entire setup is light enough to carry to a backyard or a dark-sky site without difficulty
- The f/11.3 focal ratio keeps chromatic aberration manageable for an achromat, meaning stars and planetary edges stay reasonably sharp
- The 2-year warranty and US-based support from Celestron add meaningful value at this price point
- Honest limitation: deep-sky performance is constrained by the 80mm aperture; this scope rewards lunar and planetary observing more than galaxy hunting

OMG, I bought this for my husband for Christmas and we all love it. It’s the families gift. You could see the stars and planets very clearly, it’s comfortable to use. It seems very professional from my perspective definitely worth the money.
This is a great first telescope for anyone interested in starting astronomy. It is light weight so you can travel and carry it easily. Easy to assemble with the manual and I am not that mechanically inclined. There are a few videos on YouTube of unboxing and assembly. It gives an excellent view of t...
This telescope is good for its price and very sturdy. With its ease of use and clarity, it’s nice for beginners and intermediate astronomers. It was very easy to set up and use. The app didn’t work well for us. We were able to eye it and get a picture of Jupiter.
