Celestron AstroMaster LT 70AZ Refractor Telescope
$157.33 price checked August 2026
If you want a telescope that is ready to use immediately without tools, this is the one to price-check.
AstroMaster LT 70AZ Overview
The Celestron AstroMaster LT 70AZ Refractor Telescope is for the budget-conscious beginner who needs a 70mm aperture to resolve lunar craters and Jupiter’s moons.
Finding a telescope that produces sharp images of the moon without blurry purple fringing is a common hurdle for new stargazers. Many entry-level scopes suffer from excessive chromatic aberration, making high-magnification viewing frustrating or impossible.
The Celestron AstroMaster LT 70AZ Refractor Telescope solves this by providing a 70mm aperture, which is the minimum diameter required to resolve lunar craters and Jupiter’s moons clearly. It includes a StarPointer and a glow-in-the-dark planisphere to help you navigate the night sky.
We selected this model from the refractor telescope options we evaluated based on its price-to-performance ratio. This review is for the budget-first shopper who wants a reliable first telescope without overspending on professional-grade glass.

The Short Answer on the AstroMaster LT 70AZ
Best for: you are a beginner who wants a complete starter kit with included accessories for learning the night sky.
The AstroMaster LT 70AZ is a solid entry point at $157.33.
- Pro: includes a glow-in-the-dark planisphere and four seasonal star charts for navigation.
- Pro: features a quick release dovetail attachment for faster mounting.
- Pro: allows for a no-tool setup to simplify initial assembly.
- Con: the 70mm aperture is below the 100mm to 130mm reference tier, limiting your ability to resolve fine lunar detail.
- Con: the Alt-Azimuth mount lacks the tracking capabilities of an Equatorial mount for long-exposure photography.
Don’t buy this if: you require a telescope with an aperture larger than 70mm to resolve lunar craters and Jupiter’s moons clearly.
Price assessment: The $157.33 price is fair for a package that includes both the telescope and essential educational materials.
RecommendedOptics score: 7.1/10 (data-driven – see “How we picked” above)

What These Specifications Let You Do
No-tool Setup Process
The Celestron AstroMaster LT 70AZ features a no-tool setup, which allows you to assemble the telescope quickly without searching for wrenches or specialized equipment. This design ensures you can move from unboxing to viewing in minutes, which is useful when you have a limited window of clear skies.
Night Navigation Tools
Night navigation tools for the AstroMaster LT 70AZ include a glow-in-the-dark planisphere and seasonal star charts for summer, winter, spring, and autumn. These tools help you identify constellations and celestial objects in the dark without needing a flashlight. The heavy card stock with a protective overcoat ensures these charts remain durable for repeated use throughout the year.
Stable Alt-Az Control
Stable Alt-Az control is provided by a pan handle with a clutch, allowing you to move the telescope smoothly across the sky. Because the AstroMaster LT 70AZ has a 70mm aperture, it is a compact option that remains easier to balance than larger models. The clutch helps prevent the telescope from drifting, which is a common failure mode in beginner refractor telescopes where mount flexure causes the image to move off-target.
Regarding the magnification you can achieve before the image becomes blurry, the 70mm aperture limits the usable magnification to approximately 70x to 100x for clear viewing. Exceeding these limits on a small aperture often results in a blurry image where you cannot see detail. To ensure the image stays steady enough to see detail, check the balance of the telescope on the mount before you begin observing; a balanced load reduces vibrations that occur when you make small adjustments to the pan handle.
Consider the compact design in our AstroMaster 102AZ spec breakdown.
How the AstroMaster LT 70AZ Compares to Alternatives
- The AstroMaster LT 70AZ costs $2.65 less than the 90mm Refractor Telescope.
- The 90mm Aperture 800mm Refractor Telescope with AZ costs $7.34 less than the AstroMaster LT 70AZ.
- The Carson Red Planet RP-400SP Refractor Telescope offers a 1000mm focal length compared to the 70mm aperture of this model.
- The White TwinStar AstroMark 80mm Refractor Telescope has an f/5.0 F-ratio, whereas the AstroMaster LT 70AZ uses an Alt-Azimuth mount with a clutch.
- The AstroMaster LT 70AZ ranks 3rd highest-rated of 5 in this comparison.
If you need a larger aperture to resolve lunar craters more clearly, you should choose the 90mm Aperture 800mm Refractor Telescope with AZ instead of this 70mm model.

Value for Money
The Celestron AstroMaster LT 70AZ costs $157.33, which sits $3 above the $154 average of the similar refractor telescope products we compared. At this price point, you receive a 70mm aperture and a mount with a pan handle and clutch. While the 70mm aperture is the minimum diameter required to resolve lunar craters and Jupiter’s moons clearly, you give up the extra-low dispersion glass found in apochromatic (ED) models, which are typically used to eliminate color fringing.
Because the data does not specify the mount’s weight capacity or material, you should check if the mount remains stable when balanced with your specific accessories to avoid mount flexure. This model is the correct choice when your priority is a complete beginner kit with seasonal star charts over the higher-contrast optics of a 3-inch to 4-inch ED refractor.
Where this sits in the buyer data: Among the 44 products screened for this category, this one’s 3.9 rating places it #30, on 237 ratings – above the 37-rating median of that group, so the average rests on more feedback than most of its comparables. On price it undercuts 51 of them.
