  • Celestron AstroMaster LT 70AZ Telescope

    The Celestron AstroMaster LT 70AZ Telescope combines a 70mm refractor objective with a 700mm focal length to deliver sharp, high-contrast views of the solar system. Its f/10 focal ratio is ideal for resolving fine planetary detail, gathering 100x more light than the human eye and reaching a limiting stellar magnitude of 11.7. The entire system weighs only 7.2 lbs, making it effortlessly portable for backyard sessions or travel, and with the included 20mm and 10mm eyepieces, you get 35x and 70x magnification right out of the box.

    70mm Refractor Optics: Resolving Jupiter's Moons and Saturn's Rings

    The heart of the AstroMaster LT 70AZ is its 70mm aperture refractor objective. This classic optical design uses fully coated glass lenses to produce bright, clear images with excellent contrast, which is critical for planetary viewing. The 700mm focal length provides the image scale needed to easily identify the cloud belts of Jupiter, the rings of Saturn, and countless craters on the Moon.

    With a Dawes' limit resolution of 1.66 arc seconds, this telescope has the optical capability to split close double stars and reveal details that are impossible to see with the naked eye. The aluminum optical tube is both lightweight at 2.5 lbs and durable, ensuring the lenses remain in alignment for consistent viewing.

    Manual Alt-Azimuth Mount: Grab-and-Go Simplicity at 7.2 lbs

    Designed for straightforward, intuitive operation, the AstroMaster LT 70AZ features a manual alt-azimuth mount that comes pre-assembled on its tripod. There's no complex alignment procedure; you simply point the telescope towards your target and look. The total kit weight of just 7.2 lbs makes it a true "grab-and-go" instrument, easy for anyone to carry outside for an impromptu observing session.

    • Steel Tripod: The adjustable-height tripod features 1.25" diameter steel legs, providing a stable platform that minimizes vibrations for steadier views.
    • Accessory Tray: A convenient tray keeps your eyepieces and other small items organized and within easy reach while you observe.
    • CG-5 Dovetail: The optical tube attaches to the mount via a standard CG-5 dovetail bar, allowing you to easily mount the tube on other compatible telescope mounts if you upgrade in the future.

    From 35x to 70x: A Complete Viewing Kit Out of the Box

    The AstroMaster LT 70AZ includes everything you need to start observing immediately. The two included 1.25" eyepieces offer distinct fields of view and magnification levels for different celestial targets. The built-on StarPointer finderscope projects a red dot onto a non-magnified window, allowing you to aim the telescope precisely by aligning the dot with your target.

    • 20mm Eyepiece (35x): This is your low-power, wide-field eyepiece. It's perfect for scanning the Moon, finding planets, and viewing larger star clusters.
    • 10mm Eyepiece (70x): Switch to this eyepiece to zoom in for more detailed views. This is the ideal magnification for studying lunar craters, observing the phases of Venus, and resolving the moons of Jupiter.
    • 90-Degree Star Diagonal: The included 1.25" diagonal provides a comfortable right-side-up, left-right correct viewing angle, making it easy to navigate the night sky.

    Celestron Software Suite: Plan Your Observations with Starry Night and SkyPortal

    Your AstroMaster LT 70AZ includes a free download of Celestron's Starry Night Basic Edition software, a powerful planetarium program that helps you learn the night sky. You can use it to see what objects are visible on any given night, print star charts, and learn about the celestial objects you are viewing. Additionally, you get access to the SkyPortal app, which turns your smartphone or tablet into a portable planetarium and observatory guide.

  • What can I see with the Celestron AstroMaster LT 70AZ?

    The AstroMaster LT 70AZ is excellent for viewing bright solar system objects. You can expect to see detailed craters on the Moon, the phases of Venus, the polar ice caps on Mars, Jupiter's four largest moons and its cloud belts, and the rings of Saturn. Brighter star clusters and nebulae are also visible from dark sky locations.

    Is the AstroMaster LT 70AZ telescope good for a beginner?

    Absolutely. It is designed for beginners with its no-tool setup, pre-assembled tripod, and simple point-and-look manual mount. The total kit weighs only 7.2 lbs, making it very easy to handle and transport. The included accessories and software provide everything a new astronomer needs to start exploring the night sky.

    How do I use the StarPointer finderscope on the AstroMaster LT 70AZ?

    The StarPointer is a red dot finder. First, you'll need to align it with the main telescope during the day. Point the telescope at a distant, stationary object (like a treetop). Then, without moving the telescope, use the finder's adjustment knobs to move the red dot until it is centered on the same object. At night, you simply look through the finder and move the telescope until the red dot is on your target, and it will be in the eyepiece's field of view.

    Can I take pictures with the AstroMaster LT 70AZ?

    While this telescope is primarily designed for visual use, you can take basic photos of the Moon by holding a smartphone camera up to the eyepiece. For more advanced astrophotography, a telescope with a computerized equatorial mount is recommended to track the motion of celestial objects.

    What is the difference between the 35x and 70x magnification on the AstroMaster LT 70AZ?

    The 20mm eyepiece provides 35x magnification, which gives you a wider, brighter field of view. This is best for finding objects and viewing large star fields like the Pleiades (M45). The 10mm eyepiece provides 70x magnification, which narrows the field of view but shows more detail on smaller targets like the cloud bands on Jupiter or the Cassini Division in Saturn's rings.

    How do I set up the AstroMaster LT 70AZ in my backyard?

    Setup is fast and requires no tools. Simply spread the legs of the pre-assembled tripod, adjust the height to your preference (from 32" to 51"), and attach the optical tube to the mount using the CG-5 dovetail knob. Place your desired eyepiece into the star diagonal, and you are ready to observe in minutes.
