Let’s Dive into Celestron AstroMaster 70 AZ Altazimuth Refractor Telescope 21061
The Celestron AstroMaster 70 AZ Altazimuth Refractor Telescope 21061 from Celestron is marketed as a dual-purpose telescope, suitable for both terrestrial and celestial viewing. This refractor telescope boasts fully coated optics, an altazimuth mount for easy maneuverability, and a sturdy tripod, making it an attractive option for beginners and intermediate users alike. Its refractor design promises ease of maintenance, appealing to those new to the world of astronomy.
My journey to finding the Celestron AstroMaster 70 AZ started with a simple desire: to share the wonders of the night sky with my kids. I wanted a telescope that was easy to set up, simple to use, and capable of providing decent views of the moon and planets, without breaking the bank. After all, fostering a love for science and exploration shouldn’t require a PhD in astrophysics or a second mortgage.
Unboxing the Celestron AstroMaster 70 AZ, I was immediately struck by the apparent sturdiness of the tripod; the 1.25″ steel legs felt solid and reliable. The telescope tube itself was lighter than expected, constructed primarily of aluminum and plastic, but it didn’t feel cheap. Assembly was straightforward, taking me less than 15 minutes with the included instructions.
I considered other telescopes, such as the Orion StarBlast 4.5 Astro Reflector Telescope and the Meade Infinity 70 AZ Refractor Telescope. Ultimately, I chose the Celestron AstroMaster 70 AZ because of the brand’s reputation and the telescope’s ease of use claim, which seemed perfect for introducing my family to astronomy. The included planetarium software was also a plus, promising a wealth of information about celestial objects.
My first impression was cautiously optimistic. The telescope seemed well-built for its price point, and the altazimuth mount felt intuitive to use. I was excited to get it outside and see what it could do, but I also tempered my expectations, remembering that this is an entry-level telescope.
Real-World Testing: Putting Celestron AstroMaster 70 AZ Altazimuth Refractor Telescope 21061 to the Test
First Use Experience
My initial test of the Celestron AstroMaster 70 AZ took place in my backyard, a suburban environment with moderate light pollution. I wanted to observe the moon, as it’s a relatively easy target for beginners. Setup was a breeze, even in the dark.
The fully coated lens did well to produce a fairly bright image of the moon. Focusing required some patience, but I was eventually rewarded with clear details of lunar craters and mountains. The 45x magnification eyepiece provided a wide field of view, which made it easy to locate and track the moon.
The altazimuth mount made the experience easier. It moved smoothly in both altitude (up and down) and azimuth (left and right). Tracking the moon across the sky required frequent adjustments, but the mount was responsive and easy to control. The tripod also provided a stable platform.
The only issue I encountered was some vibration when focusing at higher magnifications using the 90x eyepiece. This made it difficult to get a truly sharp image. It took some practice to minimize the vibrations and achieve a stable view.
Extended Use & Reliability
After several weeks of use, the Celestron AstroMaster 70 AZ has held up surprisingly well. I’ve used it in various conditions, including cold nights and mildly humid evenings, without any noticeable degradation in performance. I’ve taken it camping as well.
The telescope tube itself has proven to be quite durable, with no scratches or dents despite being transported in my car. The tripod remains sturdy, although I’ve noticed a few minor scuff marks on the steel legs.
Maintenance has been minimal; I simply wipe the lens with a microfiber cloth after each use to remove dust and fingerprints. The refractor design is easy to maintain since it reduces the need for collimation that reflectors require. I also keep the telescope stored in its original box when not in use to protect it from the elements.
Compared to my previous experiences with binoculars, the Celestron AstroMaster 70 AZ offers a significantly improved viewing experience, particularly for celestial objects. The increased magnification and larger aperture reveal details that are simply not visible with binoculars. However, compared to higher-end telescopes I’ve used, the AstroMaster lacks the resolving power and light-gathering ability to reveal fainter deep-sky objects.
Breaking Down the Features of Celestron AstroMaster 70 AZ Altazimuth Refractor Telescope 21061
Specifications
The Celestron AstroMaster 70 AZ Altazimuth Refractor Telescope 21061 features a 70mm aperture, which is the diameter of the objective lens. A larger aperture gathers more light, resulting in brighter and more detailed images. It has a focal length of 900mm, which determines the telescope’s magnification capabilities.
The focal ratio is 12.86, calculated by dividing the focal length by the aperture. A higher focal ratio generally results in narrower field of view and higher magnification. The telescope comes with two eyepieces: a 20mm eyepiece providing 45x magnification and a 10mm eyepiece providing 90x magnification.
The mount is an altazimuth mount, which allows the telescope to be moved up and down (altitude) and left and right (azimuth). This type of mount is intuitive to use and well-suited for both terrestrial and celestial viewing. The optics are fully coated, meaning that all lens surfaces have been treated with an anti-reflective coating to maximize light transmission and improve image contrast. The telescope weighs 18 lb (8.16 kg), including the tripod. It comes with a 2-year warranty.
Performance & Functionality
The Celestron AstroMaster 70 AZ performs admirably as an entry-level telescope, providing decent views of the moon, planets, and some brighter deep-sky objects. It’s reliable and easy to use. It gives new astronomers a chance to learn the ropes.
Its strengths lie in its ease of setup, simple operation, and relatively low cost. The views of the moon are particularly impressive, revealing a wealth of detail on the lunar surface. The planets Jupiter and Saturn are also visible, although the details are limited by the telescope’s aperture. One improvement would be to increase the magnification of the eyepieces.
While the AstroMaster 70 AZ meets expectations for an entry-level telescope, it does have some limitations. Its relatively small aperture limits its ability to reveal fainter deep-sky objects. The included eyepieces could be of higher quality, and the vibrations at higher magnifications can be frustrating.
Design & Ergonomics
The Celestron AstroMaster 70 AZ features a simple and functional design. The aluminum telescope tube is lightweight and easy to handle, while the plastic components feel reasonably durable. The telescope can handle the rigors of occasional transport and outdoor use.
The altazimuth mount is intuitive to use, allowing for smooth and precise movements. However, the mount can feel slightly wobbly at higher magnifications. Some users will find it lacking in comparison to a more stable equatorial mount.
Durability & Maintenance
The Celestron AstroMaster 70 AZ appears to be reasonably durable, capable of withstanding typical use and transport. The refractor design requires minimal maintenance, with only occasional cleaning of the lens necessary. Storing the telescope in a dry place is critical.
The telescope’s lifespan will likely depend on how well it is cared for. Regular cleaning and proper storage will help to extend its longevity. Consider purchasing a dedicated carrying case for added protection.
Accessories and Customization Options
The Celestron AstroMaster 70 AZ comes with two eyepieces (20mm and 10mm), a StarPointer finderscope, and a tripod. The finderscope is helpful for locating objects in the night sky. There’s also an accessory tray that attaches to the tripod for storing eyepieces and other small items.
Aftermarket accessories, such as higher-quality eyepieces and filters, can enhance the telescope’s performance. The AstroMaster 70 AZ is compatible with standard 1.25″ eyepieces, offering a wide range of customization options. Consider purchasing a Barlow lens to increase the magnification of your existing eyepieces.
