Celestron AstroMaster 70 AZ Altazimuth Refractor Telescope 21061 Review

The Celestron AstroMaster 70 AZ Altazimuth Refractor Telescope 21061 and What It Taught Me

The Celestron AstroMaster 70 AZ Altazimuth Refractor Telescope 21061 is marketed as a dual-purpose telescope suitable for both terrestrial and celestial viewing, aimed primarily at beginners and intermediate users. With a 70mm aperture, fully coated optics, and an easy-to-use altazimuth mount, this telescope promises to deliver clear images of the moon, planets, and even some deep-sky objects. This telescope seemed like the perfect entry point into the world of astronomy for my family and me.

My interest in the Celestron AstroMaster 70 AZ Altazimuth Refractor Telescope 21061 stemmed from a desire to share the wonders of the night sky with my children. Living in a relatively dark area, I wanted a tool that could introduce them to the basics of astronomy without breaking the bank. The promise of both terrestrial and celestial viewing was also appealing, as I envisioned using it for birdwatching and landscape observation during the day.

The unboxing experience was straightforward; all the components were neatly packed and easily identifiable. The tripod legs felt surprisingly sturdy for the price point, and the optical tube had a decent weight to it, suggesting reasonable build quality. Assembling the telescope took less than 15 minutes, and the instructions were clear and easy to follow, a major plus for a beginner-friendly product.

I considered the Orion StarBlast 4.5 Astro Reflector and the Meade Infinity 70mm AZ Refractor before ultimately choosing the Celestron AstroMaster 70 AZ Altazimuth Refractor Telescope 21061. The Celestron edged out the Orion due to its dual-purpose capability, while the Meade seemed slightly less robust in its tripod construction. The Celestron also had a slightly longer focal length, promising better magnification for planetary viewing.

My first impression was one of cautious optimism; the telescope looked the part, but I reserved judgment until I could test its optical performance under the night sky. The altazimuth mount seemed intuitive, but I wondered if it would be stable enough for higher magnification viewing.

Real-World Testing: Putting Celestron AstroMaster 70 AZ Altazimuth Refractor Telescope 21061 to the Test

First Use Experience

My first outing with the Celestron AstroMaster 70 AZ Altazimuth Refractor Telescope 21061 was in my backyard on a clear, moonlit night. The temperature was around 50 degrees Fahrenheit, and there was minimal wind. My primary target was the Moon, as its brightness made it an easy object to locate and observe.

The telescope performed admirably on the Moon, revealing impressive details of craters and lunar maria. Focusing was relatively easy, although the focus knob felt a little stiff. Switching between the 20mm and 10mm eyepieces provided noticeable magnification differences, although the image quality degraded slightly at the higher magnification.

I did encounter some initial difficulties with the StarPointer finderscope; it required careful alignment to accurately point the telescope at desired objects. After some adjustments, however, it proved to be a valuable tool for navigating the night sky. The altazimuth mount, while easy to use, exhibited some minor vibrations, especially when focusing or making adjustments at higher magnifications.

Extended Use & Reliability

After several weeks of using the Celestron AstroMaster 70 AZ Altazimuth Refractor Telescope 21061, I’ve gained a better understanding of its strengths and limitations. The telescope continues to perform well for lunar and planetary viewing, consistently delivering sharp and detailed images of the Moon, Jupiter, and Saturn. Deep-sky objects, such as nebulae and galaxies, are visible as faint smudges, but the small aperture limits their resolution and brightness.

The Celestron AstroMaster 70 AZ Altazimuth Refractor Telescope 21061 has held up well over time, showing no signs of significant wear and tear. The optical tube remains scratch-free, and the tripod legs have retained their stability. I’ve kept the lenses clean using a microfiber cloth and lens cleaning solution, which has helped maintain optimal image quality.

Maintaining the Celestron AstroMaster 70 AZ Altazimuth Refractor Telescope 21061 is quite easy, requiring only occasional cleaning of the lenses and dusting of the tripod. The refractor design minimizes the need for collimation, a common maintenance task for reflector telescopes. Overall, it’s a low-maintenance instrument that’s well-suited for casual observers.

Compared to my previous experiences with binoculars, the Celestron AstroMaster 70 AZ Altazimuth Refractor Telescope 21061 offers a significantly enhanced viewing experience. The telescope’s greater magnification and light-gathering capabilities reveal details that are simply not visible with binoculars. However, it’s important to acknowledge that this telescope is not a high-end instrument and has limitations in terms of aperture and mount stability.

Breaking Down the Features of Celestron AstroMaster 70 AZ Altazimuth Refractor Telescope 21061

Specifications

• Optical Design: Refractor – This design uses lenses to focus light, offering ease of use and low maintenance.
• Aperture: 70 mm (2.76 in) – This determines the telescope’s light-gathering ability, impacting the brightness and detail of observed objects.
• Focal Length: 900 mm (35.43 in) – This influences the telescope’s magnification capabilities, with longer focal lengths generally providing higher magnification.
• Focal Ratio: 12.86 – A higher focal ratio indicates a narrower field of view and better performance for high-magnification viewing of planets and the Moon.
• Eyepiece 1: 20 mm (0.79 in) – This provides a magnification of 45x, suitable for wide-field views of the Moon and brighter objects.
• Eyepiece 2: 10 mm (0.39 in) – This offers a higher magnification of 90x, ideal for detailed observations of planets and lunar features.
• Mount: Altazimuth – This simple mount allows for movement in both altitude (up and down) and azimuth (left and right), making it intuitive for beginners.
• Optical Coatings: Fully Coated – These coatings reduce light loss and improve image brightness and contrast.
• Weight: 18 lb (8.16 kg) – This makes it portable enough for transport to darker viewing locations.
• Warranty: 2 years – Celestron provides a standard warranty against manufacturing defects.

These specifications matter because they collectively determine the telescope’s overall performance and suitability for different types of observing. The 70mm aperture provides a reasonable balance between light-gathering ability and portability, while the 900mm focal length allows for decent magnification of planets and the Moon.

Performance & Functionality

The Celestron AstroMaster 70 AZ Altazimuth Refractor Telescope 21061 performs its job reasonably well, providing clear views of the Moon, planets, and brighter deep-sky objects.
