Celestron AstroMaster 70AZ Features Explained

Achromatic Optical Tube and Daytime Viewing

At the center of this setup is a 70mm (2.8-inch) objective lens with a 900mm focal length, housed in an optical tube measuring 68.5 centimeters. The fully coated achromatic glass focuses light efficiently while keeping distortion manageable across planetary targets and open star clusters. Because refractors use a sealed optical path, the internal lenses stay shielded from dust, sand, and moisture shifts during transit, providing dependable durability for vehicle packing. For stargazers evaluating the celestron inspire 100az or similar refractor lines, the 70AZ offers a narrower aperture that remains notably easier to stow in tight vehicle trunks.

A key advantage of the celestron astromaster 70az refractor telescope design is its included erect image star diagonal. Unlike astronomical reflectors or traditional diagonals that flip or invert the field of view, this configuration renders images correctly oriented right-side up and left-to-right. This capability transforms the telescope into an oversized spotting scope during daylight hours, allowing mobile explorers to scan distant mountains, coastline landmarks, or resting wildlife across valleys before switching over to moon gazing at dusk.

Manual Alt-Azimuth Panhandle Mount

Outdoor observers often want simplicity when deploying gear away from home. The celestron 70az alt-azimuth mount utilizes an intuitive panhandle mechanism to steer the optical tube up, down, left, and right. Because tracking is completely manual, there are no motorized gearboxes to drain power or motors to stall in cold weather. While computerized systems like the celestron starsense explorer dx 130az rely on smartphone integration and automated sky-mapping algorithms, this manual alt-azimuth design keeps the stargazing experience tactile, straightforward, and independent of electronic devices.

Navigating the night sky with the panhandle allows you to smoothly pan across constellations or re-center objects as Earth rotates. Tightening the handle locks the telescope on target, while loosening it enables fluid altitude adjustments. The simplicity of this mechanism makes it especially accommodating for younger family members and beginners who might feel intimidated by complicated equatorial counterweights or polar axis calibrations during field sessions.

Tool-Free Tripod and Field Assembly

Field deployment is where the celestron astromaster 70 setup truly stands out for travel enthusiasts. The package features an adjustable full-height tripod that assembles without any screwdrivers, wrenches, or specialized hardware. The legs extend and lock smoothly, allowing you to adapt the platform height whether you prefer standing on uneven campsite dirt or sitting comfortably in a camp chair. The complete package has assembled dimensions of 27 inches deep by 32 inches wide by 51 inches high, establishing a stable viewing stance without overwhelming compact campsite clearings.

When packing light for long road trips, the celestron astromaster 70 weight is a key consideration. At an item weight of 10.8 pounds, the entire system—including the optical tube, tripod, and mount—can be carried in one trip from the vehicle to an elevated observation ridge. The modular breakdown lets you detach the optical tube from the tripod assembly in seconds, making it easy to nestle the individual components between duffels, sleeping bags, and camping storage crates in a car trunk.

Eyepieces, Finder, and Accessory Bundle

Celestron supplies two distinct eyepieces with the 70AZ: a 20mm eyepiece and a 10mm eyepiece. Paired with the 900mm focal length, the 20mm eyepiece produces a wider field of view suitable for scanning expansive star fields, open star clusters, and whole lunar landscapes. Swapping to the 10mm eyepiece provides higher magnification, narrowing the field of view to focus on prominent impact craters, lunar mountain ranges, and basic planetary details. The optical system specifies a zoom ratio of 45 multiplier x, an exit pupil diameter of 1.56 millimeters, and a Dawes limit resolution rating of 1.66 arc-seconds.

Target acquisition in the field is assisted by a StarPointer red dot finderscope, which projects a small illuminated reticle against the sky to help you guide the main barrel onto visible targets. The finderscope is powered by one included lithium metal battery, representing the only battery component in the entire hardware setup. The package also includes a free download of astronomy software compatible with personal computers, giving you a digital planetarium to study celestial charts and plan observation sessions before hitting the road.

Before You Buy

Before packing the telescope for an extended excursion, keep in mind what the listing does and does not provide. While the StarPointer red dot finderscope includes its required lithium metal coin battery, the primary telescope and alt-azimuth mount operate entirely through manual mechanics. The listing does not specify any motorized tracking, motorized clock drives, or automated target-finding assistance. If you are accustomed to wireless accessories like the celestron skyportal wifi module for tablet-guided navigation, note that this refractor relies entirely on manual hand-tracking and manual visual star-hopping.

Storage and packing configurations also require careful forethought. The listing includes the optical tube, tripod, two eyepieces, an erect image diagonal, and a finderscope, but it does not specify a padded travel bag, dedicated carrying case, or smartphone camera adapter. With an optical tube length of 68.5 centimeters (roughly 27 inches) and a full-height tripod, travelers will need to allocate sufficient trunk width or backseat room to safely transport the bare tube without scratching the fully coated optics. If your mobile stargazing workflow demands smartphone photography adapters or dedicated field backpacks, those accessories must be acquired separately as they are absent from this stock retail package.
