What Makes Celestron AstroMaster LT 70AZ Telescope 21074 Stand Out?
The Celestron AstroMaster LT 70AZ Telescope 21074 promises an accessible entry point into the world of astronomy, a pursuit that has captivated humanity for millennia. Celestron, a well-respected name in amateur astronomy, aims to deliver a telescope that’s both user-friendly and capable. Its 70mm aperture and altazimuth mount are designed to provide satisfying views of the Moon, planets, and brighter deep-sky objects without overwhelming beginners with complexity.
My own journey into stargazing began with a similar desire: to witness the cosmos firsthand. I wanted to share that sense of wonder with my kids. I needed a telescope that was easy to set up and use, something that wouldn’t gather dust in the closet after a single frustrating attempt.
The Celestron AstroMaster LT 70AZ arrived neatly packaged. My first impression was of its portability. It felt lightweight yet reasonably sturdy; I was impressed. It was noticeably more compact than some of the larger, more intimidating telescopes I’d seen.
Compared to, say, a more complex reflector telescope with an equatorial mount, the AstroMaster LT 70AZ seemed refreshingly straightforward. A computerized “GoTo” telescope promised push-button ease, but I valued the learning experience of manually navigating the sky. I also considered a smaller, tabletop Dobsonian telescope, but its lack of a full-sized tripod seemed limiting. The Celestron’s combination of aperture, portability, and ease of use won me over.
My initial excitement was tempered by a healthy dose of skepticism. Could such an affordable telescope truly deliver satisfying views? I was eager to find out.
Real-World Testing: Putting Celestron AstroMaster LT 70AZ Telescope 21074 to the Test
First Use Experience
I first tested the Celestron AstroMaster LT 70AZ Telescope 21074 in my backyard. The site has moderate light pollution from nearby streetlights. The setup was remarkably quick and easy, living up to Celestron’s claim of tool-free assembly. The pre-assembled tripod felt stable enough, and the quick-release dovetail attachment made mounting the telescope tube a breeze.
The permanently mounted StarPointer finderscope was surprisingly helpful for initial alignment. Aligning the finderscope with a distant object during daylight made navigating the night sky much easier. The altazimuth mount, while simple, required some getting used to. It took a few tries to smoothly track objects as they drifted across the field of view.
On my first night, the skies were clear, and the Moon was a waxing gibbous. The views through the Celestron were crisp and detailed. I was impressed by the craters and maria visible with the 20mm eyepiece. Even with some light pollution, I managed to spot Jupiter and its four Galilean moons as tiny points of light. The experience was genuinely exciting, confirming that this telescope had real potential.
Extended Use & Reliability
After several weeks of use, the Celestron AstroMaster LT 70AZ Telescope 21074 has held up well. I’ve taken it to a darker location outside the city, and the increased contrast has allowed me to see fainter objects like the Orion Nebula. The telescope shows no signs of significant wear and tear. The paint is still intact, and the tripod remains stable.
The telescope requires minimal maintenance. I’ve kept the optics clean with a microfiber cloth and lens cleaning solution. The altazimuth mount still operates smoothly, requiring only occasional tightening of the clutch.
Compared to the binoculars I previously used for stargazing, the Celestron offers significantly higher magnification and detail. While a larger aperture telescope would undoubtedly provide brighter and sharper images, the AstroMaster LT 70AZ strikes a good balance between performance, portability, and ease of use, making it an excellent choice for beginners like my family.
Breaking Down the Features of Celestron AstroMaster LT 70AZ Telescope 21074
Specifications
- Aperture: 70mm. This determines the telescope’s light-gathering ability. A larger aperture collects more light, allowing you to see fainter and more distant objects.
- Focal Length: 700mm. This specification, along with the eyepiece focal length, determines the telescope’s magnification.
- Mount Type: Altazimuth. This simple and intuitive mount allows you to move the telescope up/down (altitude) and left/right (azimuth), like a camera tripod.
- Finderscope: Permanently Mounted StarPointer. This helps you aim the telescope by projecting a red dot onto the sky.
- Eyepieces: 20mm (35x) and 10mm (70x). These provide different levels of magnification for viewing celestial objects.
- Maximum Useful Magnification: 165x. This is the highest practical magnification before image quality degrades significantly.
- Tripod: Pre-assembled with 1″ Steel Tube Legs. Offers a stable base for the telescope.
- Software: SkyX Astronomy Software (10,000 Object Database). Provides a virtual planetarium on your computer.
- Warranty: 2 Year. Celestron stands behind their product.
These specifications matter because they define the telescope’s capabilities and limitations. The 70mm aperture is sufficient for observing the Moon, planets, and some brighter deep-sky objects. The altazimuth mount is easy to use, but can be less precise than an equatorial mount for long-exposure astrophotography.
Performance & Functionality
The Celestron AstroMaster LT 70AZ Telescope 21074 performs admirably for its intended purpose. It provides clear and sharp views of the Moon’s craters, Jupiter’s moons, and Saturn’s rings.
Its strengths lie in its ease of setup, user-friendly operation, and portability. The StarPointer finderscope makes locating objects relatively straightforward, even for beginners. The included eyepieces offer a good range of magnifications for different types of observing.
The main weakness is its limited aperture, which restricts the visibility of fainter deep-sky objects. The altazimuth mount can also make tracking objects at higher magnifications challenging, requiring frequent adjustments.
Overall, the AstroMaster LT 70AZ meets expectations for an entry-level telescope.
Design & Ergonomics
The Celestron AstroMaster LT 70AZ Telescope 21074 features a simple and functional design. The materials are primarily plastic and aluminum, which contribute to its lightweight construction. The telescope feels reasonably sturdy, though some components, like the focuser knobs, could be more robust.
The telescope is generally user-friendly, with a minimal learning curve. The altazimuth mount is intuitive to operate, and the quick-release dovetail attachment makes attaching and detaching the telescope tube quick and easy.
Durability & Maintenance
With proper care, the Celestron AstroMaster LT 70AZ Telescope 21074 should last for several years. Its durability is reasonable for its price point.
Maintenance is simple. Keeping the optics clean and storing the telescope in a dry place will help prolong its lifespan.
Accessories and Customization Options
The Celestron AstroMaster LT 70AZ Telescope 21074 comes with two eyepieces (20mm and 10mm) and the StarPointer finderscope. The included SkyX software provides a database of 10,000 celestial objects.
While customization options are limited, you can purchase additional eyepieces to achieve different magnifications. A Barlow lens can double or triple the magnification of existing eyepieces. The telescope is compatible with standard 1.25-inch eyepieces from other brands, expanding the possibilities.
