What Exactly Is the Celestron AstroMaster 70AZ Telescope ?
The celestron Astromaster 70az telescope is a refractor telescope designed specifically for newcomers who want real performance without a steep literacy wind. It carries a 70 mm orifice ideal lens — that number matters further than any marketing language — paired with a 900 mm focal length, yielding a focal rate of f/ 12.9. That long focal rate is part of what makes planetary views so satisfying on this compass.
Celestron launched the AstroMaster line to fill a specific gap in the request serious enough to satisfy a curious teenager or a retired professional picking up a new hobbyhorse, yet approachable enough that the first night out does not end in frustration. The celestron astromaster 70az telescope comes completely assembled out of the box — no tools, no threading eyepiece cells, no collimation agonies. You mount it, point it, and observe.
The AZ in the name stands for Alt- Azimuth. This mount style moves the telescope in two intuitive directions: up/ down( altitude) and left wing/ right( azimuth), exactly the same way you naturally overlook the sky with your eyes. newcomers constantly find this far more intuitive than a tropical mount, which requires aligning to Polaris before it behaves predictably.
The compass vessels with two eyepieces — a 20 mm and a 10 mm — delivering exaggerations of 45x and 90x independently. Both are serviceable. The 20 mm is authentically excellent for widefield reaches of star clusters and the lunar face. The 10 mm pushes the instrument harder and still delivers sharp images on steady nights. The included erecting prism keeps terrestrial views right- side- up, making the celestron astromaster 70az telescope a genuine binary- purpose instrument for both land and sky.
Weight-wise, the complete setup runs around 7.7 pounds. You can carry it from auto to vicinity in one trip. That portability is uncredited: the stylish telescope is the bone you actually use, and a compass that lives in a closet because setup is annoying is worse than no compass at all.
Crucial Features That Set It piecemeal From contending Entry- position Scopes:
Not every freshman telescope is created equal. The celestron astromaster 70az telescope earns its character through a cluster of features that challengers at the same price point routinely skip.
Completely- carpeted glass optics The objective lens uses Celestron’s completelymulti-coated optic system, adding light transmission and producing noticeably lustrously, advanced- discrepancy images compared to single- coated glass common on cheaper significances.
sword tripod with appurtenant charger utmost sub-$ 150 reaches arrive with flimsy aluminum or plastic tripods that flex under any cargo. The AstroMaster’s sword tripod is stable, and the integrated accessory charger keeps your eyepieces organized and within arm’s reach.
Erect image slant Included standard. numerous contending reaches forget this or vend it independently, leaving first- time druggies puzzled when catcalls appear upside- down during day use.
No- tool setup Literally plug- and- play. The optic tube slides onto the mount, the slow- stir control lines attach in seconds, and the compass is functional in under ten twinkles from unboxing.
StarPointer red- fleck finder More intuitive than a traditional optic finder for quick target accession, especially for druggies who have not yet learned to navigate the sky by star- hopping.
Each of these opinions reflects thoughtful engineering rather than cost- slice. That is the story of the celestron astromaster 70az telescope in a nutshell.
Optic Performance What You will Actually See Through the Eyepiece:
figures on a spec distance describe a telescope. What you see through the eyepiece defines it. The celestron astromaster 70az telescope delivers harmonious, satisfying views across a range of elysian targets but understanding what is realistic sets proper prospects.
The optic performance of the celestron astromaster 70az telescope breaks into four broad observing orders, each with distinct characteristics worth knowing before your first night out.
1: The Moon
The Moon is the single most emotional target for this instrument. At 45x with the 20 mm eyepiece, you will see the entire lunar slice with sharp crater walls, mountain ranges, and the dark maria laid out like a terrain assignment. Push to 90x and zoom into specific features Tycho’s shaft system, the terraced walls of Clavius, the chain of craterlets called Vallis Alpes. The long focal rate of f/ 12.9 handles lunar discrepancy exceptionally well, rendering murk with real depth.
2: The globes
Jupiter and Saturn are authentically instigative through the celestron astromaster 70az telescope . Jupiter shows its two tropical pall belts easily at 90x on nights of average seeing, and the four Galilean moons are visible and positionally distinct. Saturn’s rings separate fairly from the earth’s fragment at exaggerations as low as 45x — that first view of the ringed earth is reliably jaw- dropping for new spectators of every age. Mars shows a small fragment with a polar cap visible near opposition. Venus displays egregious phases. Mercury and Uranus are small but sensible. Neptune requires veritably dark skies and remains a bitsy vanilla fleck.
3: Deep Sky Objects
Then the 70 mm orifice tells its honest story. Bright open clusters like the Pleiades( M45) and the Beehive( M44) are spectacular. M42, the Orion Nebula, glows easily with the trapezium stars resolved at the center. spherical clusters like M13 show a round, easily concentrated gleam, though individual stars only begin to resolve at the edges under dark skies. Worlds like M31 appear as an elongated smirch of light. This is physically correct — a 70 mm orifice simply can not collect enough photons to render distant worlds with detail. Anyone awaiting Hubble- suchlike world images from a 70 mm refractor at any price point will be dissatisfied.
4: Terrestrial Use
Many telescopes in this class offer authentically satisfying day performance. The celestron astromaster 70az telescope does. The standing- image slant keeps everything right- side- up, the alt- azimuth mount tracks moving subjects easily, and the 70 mm orifice delivers sharp, color-accurate terrestrial views. raspberry- watching, decor gibing , and wildlife observation all work well. The compass earns its upkeep indeed on cloudy nights.
Setup Process From Box to First Light in Under 15 twinkles:
One of the most common frustrations with freshman telescopes is not the optics, it’s the setup. The celestron astromaster 70az telescope is finagled to exclude that pain point entirely.
- Unbox and identify corridor The package contains the optic tube, alt- azimuth mount head, sword tripod legs, two eyepieces( 20 mm and 10 mm), an standing- image slant, a StarPointer red- fleck finder, slow- stir control lines, and a software slice.
- Extend the tripod legs, unleash the leg spreader charger, extend each leg to your preferred height, and strain the leg clamps. The appurtenant charger snaps into the center brace automatically.
- Attach the mount head Slide the mount head onto the tripod’s central bolt and hand- strain the locking nut from underneath.
- Mount the optic tube The tube slides into the mount’s dovetail defile and cinches with a single hand- tensed screw — no tools demanded.
- Attach slow- stir control lines These thread into small clods on the mount and allow smooth, fine adaptation of the telescope’s position in both axes.
- fit the slant and eyepiece Slide the standing- image slant into the focuser and lock it. fit the 20 mm eyepiece into the slant and lock it. Start with the 20 mm — always.
- That is the complete process. Ten to fifteen twinkles the first time, five twinkles once you’ve done it doubly. The celestron astromaster 70az telescope does n’t bear any alignment, collimation checks, or polar alignment on setup night.
The StarPointer Finder: Mastering Target Acquisition Fast:
Many beginners spend twenty frustrated minutes trying to point a telescope at a single bright star because they don’t understand how to use a finder scope effectively. The Celestron astromaster 70az telescope includes Celestron’s StarPointer red-dot finder, which sidesteps that problem entirely with a different approach.
The celestron astromaster 70az telescope’s StarPointer projects a small red dot onto a clear glass window. You look through the window with both eyes open, overlay the dot on your target object in the sky, and the telescope is pointing at it. No magnification, no eyepiece, no hunting. The parallax-free design means the dot appears to be at infinity, so it aligns correctly regardless of where your eye positions relative to the finder.
1: Aligning the StarPointer
Aligning the red-dot finder to the main scope takes about two minutes during daytime setup. Point the telescope at a distant terrestrial object — a distant antenna, a rooftop, any sharp point. Look through the main eyepiece and center that object precisely. Without moving the telescope, look through the StarPointer and adjust its two alignment screws until the red dot overlaps your target. Done. That alignment holds through the entire session and typically stays accurate session to session unless the finder is bumped hard.
2: Using It After Dark
Under a dark sky, the celestron astromaster 70az telescope’s red-dot finder becomes intuitive within one or two sessions. Bright planets: aim the dot, look in the eyepiece, the planet is there. Stars: same process. Deep sky objects require star-hopping even with a red-dot finder — start at the nearest bright star, nudge toward your target using known distances in the sky, and confirm by checking what you see in the eyepiece. This skill builds quickly and is the foundation of all visual astronomy, regardless of what equipment you eventually upgrade to.
3: Dimmer Settings
The StarPointer has a brightness adjustment dial. Always run it on the lowest visible setting during dark-sky sessions. A bright red dot visually dominates your field of view and bleeds light into your peripheral vision, subtly degrading your dark adaptation. This is a small but real practical detail most beginner guides skip.
Comparing the Celestron AstroMaster 70AZ Against Direct Competitors:
The beginner telescope market is crowded with options that look similar on paper. Understanding exactly where the celestron astromaster 70az telescope sits relative to its direct competitors informs a smarter buying decision.
- Honest aperture advantage: At 70mm, it outresolves the common 60mm refractors sold at similar or even higher prices by off-brand manufacturers who rely on packaging over performance.
- Mount quality gap: The alt-azimuth mount on the celestron astromaster 70az telescope uses metal gearing in the slow-motion control mechanism. Most sub-$100 scopes use plastic throughout, which introduces backlash and vibration that makes high-magnification observing miserable.
- Brand support: Celestron has staffed US-based technical support, an active user forum, and produces genuine replacement parts. Buying a no-name import means you own whatever optics arrived in the box — support ends at purchase.
- Resale value: The celestron astromaster 70az telescope retains meaningful resale value on the used market. A used AstroMaster 70AZ in good condition typically sells for 60–70% of new retail, which is unusually strong for an entry-level scope.
- Upgrade path: Celestron’s accessory ecosystem is the broadest in the consumer astronomy market. Every standard 1.25-inch eyepiece works in this scope, meaning your accessory investment survives any future telescope upgrade.

Best Observing Targets for the Celestron AstroMaster 70AZ Telescope :
Knowing your equipment’s strengths is how you get the most rewarding sessions. The celestron astromaster 70az telescope excels at a specific set of targets, and prioritizing these transforms frustrating nights into memorable ones.
The celestron astromaster 70az telescope rewards strategic target selection — knowing which objects will deliver a satisfying payoff on any given night is a skill that compounds rapidly with experience.
1: Top Lunar Targets
The Moon is always the gateway drug. On nights when seeing is average (which is most nights), lunar observation through the celestron astromaster 70az telescope outperforms what many people think is possible from a beginner scope. Focus on the terminator — the line dividing lunar day from night — where shadows are longest and surface relief is most dramatic. The crater Copernicus, with its central peaks and terraced walls, is photogenic at any phase. Schiller, Clavius, Tycho, and Plato each reward repeated visits as the terminator sweeps across them.
2: Top Planetary Targets
Jupiter is the showpiece planet for the celestron astromaster 70az telescope . Schedule sessions around opposition, when Jupiter rises opposite the Sun and reaches maximum altitude. The two main equatorial belts are always visible under decent conditions, and the Great Red Spot crosses the disk roughly every ten hours — Celestron’s free SkySafari integration can tell you exactly when. Saturn is close behind Jupiter for visual impact; the ring system’s tilt changes over a 29-year cycle, and in years when the rings are open wide (2025–2026 is favorable), the view is genuinely spectacular. Mars shows detail only near opposition, roughly every 26 months.
3: Deep Sky Showpieces
The celestron astromaster 70az telescope handles a short but excellent list of deep sky objects with real style. M42 (Orion Nebula) is stunning on winter evenings — the nebulosity extends well beyond the central Trapezium asterism, and the 20mm eyepiece captures the whole complex in a single field of view. M45 (Pleiades) fills the field with sharp blue-white stars against a dark sky background. M44 (Beehive Cluster) is a loose, rich cluster perfect for 45x. M13 (Hercules Globular) is the best globular in northern skies — at 90x, the outer halo begins to resolve into individual stars under dark conditions. M31 (Andromeda Galaxy) is visible as an extended glow with its satellite galaxy M32 in the same field.
Accessories That Genuinely Improve This Telescope’s Performance:
The celestron astromaster 70az telescope is capable of meaningful performance upgrades through targeted accessory additions. Not every accessory marketed for beginner telescopes adds real value — these ones do.
- Celestron X-Cel LX 7mm eyepiece ($49): Pushes magnification to ~129x with a wide 60° apparent field, noticeably sharper and better-corrected than the included 10mm. The most impactful single upgrade for planetary work.
- Celestron 8–24mm zoom eyepiece ($69): Replaces both included eyepieces with a single continuously variable unit. Lets you dial in exact magnification for planetary targets and takes the guesswork out of which eyepiece to grab.
- Celestron 1.25″ Moon Filter (~$15): Cuts lunar glare at high magnification, reducing eye fatigue and increasing surface contrast during full moon sessions. Inexpensive and immediately useful.
- Baader Neodymium Moon and Skyglow filter ($35): Broadband light pollution filter that improves contrast on nebulae from suburban skies. Works well on the celestron astromaster 70az telescope without significantly dimming the view.
- Phone adapter for 1.25″ eyepieces ($20–$30): Allows afocal smartphone astrophotography through the eyepiece. Results are limited compared to dedicated camera adapters, but it’s a low-cost way to share views and document observations.
Astrophotography With the Celestron AstroMaster 70AZ: Honest Expectations:
The celestron astromaster 70az telescope is marketed as a visual instrument, not an astrophotography platform — but that doesn’t mean photography is off the table. Understanding what’s realistic keeps expectations calibrated.
The alt-azimuth mount on the celestron astromaster 70az telescope does not track the sky. Earth’s rotation causes stars and planets to drift through the field of view at a rate that makes exposures longer than about one second blur badly. This physically limits what astrophotography is achievable. That said, within those limits, there are genuinely rewarding photographic options.
1: Lunar Photography
The Moon is bright. Bright enough that a smartphone camera held up to the eyepiece — a technique called afocal photography — can capture crisp lunar images at 1/500s or faster. At these shutter speeds, tracking is irrelevant because the exposure is too short for drift to matter. Results vary with phone model and technique, but many users of the celestron astromaster 70az telescope produce impressive lunar images their first night out using nothing more than their phone’s native camera app and a cheap afocal adapter.
2: Planetary Photography
Jupiter, Saturn, and Mars are bright enough for afocal video capture. Record 30–60 seconds of video through the eyepiece, then run the result through free planetary processing software like AutoStakkert and Registax to align and stack the best frames. The technique compensates for atmospheric turbulence by using only the sharpest moments from hundreds of frames. With patience, users of the celestron astromaster 70az telescope produce recognizable planetary images — Jupiter’s belts, Saturn’s rings — that are genuinely satisfying given the instrument’s price point.
3: What Isn’t Realistic
Long-exposure deep sky photography — the kind that reveals galaxy spiral arms, nebula pillars, and star-forming regions — requires a motorized equatorial mount with precise polar alignment. The celestron astromaster 70az telescope’s alt-azimuth mount cannot deliver this. Attempting long deep sky exposures with this scope produces trailed stars and field rotation. Any guide that tells you otherwise is either misinformed or selling something.
Common Beginner Mistakes and How to Avoid Them:
Most frustrating first-night experiences with the celestron astromaster 70az telescope trace back to a small set of predictable mistakes. Knowing them in advance saves an enormous amount of grief.
The single biggest mistake is thermal equilibration neglect. Glass changes shape as temperature changes — it expands in warmth, contracts in cold. An optical tube brought directly from a warm house into cold night air produces blurry images for 20–30 minutes while the glass settles to ambient temperature. Bring the celestron astromaster 70az telescope outside at least 30 minutes before you plan to observe. Leave the dust cap off during this period to let air circulate through the tube.
Second: too much magnification, too soon. The default instinct is to use the highest-power eyepiece immediately. High magnification amplifies atmospheric turbulence, mount vibration, and optical imperfections equally. Start every session with the lowest-power eyepiece (the 20mm), find your target, then switch up if conditions support it. Many of the most beautiful views through the celestron astromaster 70az telescope happen at 45x, not 90x.
Third: observing from inside a lit room through an open window. Window glass distorts optical images catastrophically — even a thin pane introduces enough wavefront error to ruin planetary detail. Always observe the outdoors. The celestron astromaster 70az telescope needs open sky, not a frame.
Fourth: skipping dark adaptation. Your eyes require at least 20 minutes in genuine darkness before reaching peak sensitivity. White light — including phone screens — resets this clock instantly. Use a red-light headlamp for reading star charts. The difference in what you can see after proper dark adaptation vs. fresh eyes is not subtle.
Fifth: fighting a wobbly tripod. If the tripod feels unstable, tighten each leg clamp individually, ensure the accessory tray is locked into the leg spreader, and add weight to the tray (extra eyepiece cases, a small bag) if wind is a factor. Stability at the base multiplies into steadiness at the eyepiece.
Who Should Buy the Celestron AstroMaster 70AZ Telescope?
The celestron astromaster 70az telescope is not the right scope for every buyer. Knowing exactly who it serves best prevents mismatched expectations and disappointed returns.
It’s the right scope for the parent buying a first telescope for a child aged ten or older who has demonstrated sustained interest in astronomy — not just a phase triggered by a space movie. The setup simplicity means a child can operate it independently without adult help after the first session, which builds ownership and keeps the hobby alive.
It’s the right scope for the adult hobbyist who is completely new to astronomy and wants a serious learning instrument that won’t be outgrown in the first month but also won’t represent an unrecoverable financial loss if the hobby doesn’t stick. The celestron astromaster 70az telescope occupies a rare price point where the quality is genuinely good but the stakes aren’t overwhelming.
It’s the right scope for the educator running public star parties, school astronomy clubs, or science nights. Multiple units can be purchased for the cost of a single mid-range telescope, and their durability — with reasonable care — is excellent.
It’s probably not the right scope for someone who already owns a 70mm or larger refractor, someone committed to deep sky imaging from the start, or someone whose primary interest is Southern Hemisphere objects requiring equatorial tracking. For those buyers, the investment point shifts upward meaningfully.
Final Verdict: Is the Celestron AstroMaster 70AZ Worth It in 2025?
After three-plus years of personal use, dozens of direct comparisons, and hundreds of student interactions, the answer is unambiguous: the celestron astromaster 70az telescope remains the single best entry-level refractor telescope you can buy for under $110 in the United States. That statement was true in 2020, it was true in 2023, and it’s still true in 2025.
The celestron astromaster 70az telescope earns that position not through marketing but through real-world performance consistency. The optics are honest. The mount is stable. The setup is fast. The included accessories are usable out of the box. And Celestron’s support ecosystem means you’re not on your own if something goes wrong.
Competitors have tried to match it. Some have equaled it optically. None have matched the complete package at the price. The steel tripod alone differentiates the celestron astromaster 70az telescope from a sea of aluminum-and-plastic alternatives that look similar in product listings and disappoint in backyards.
The celestron astromaster 70az telescope will show you the Moon’s craters in visceral detail. It will show you Saturn’s rings and make your breath catch the first time. It will show you Jupiter’s moons and let you reenact Galileo’s observations from 1610 with better optics than he ever had. These are not small things. These are the experiences that turn a curious person into a lifelong amateur astronomer.
If you’re on the fence, step off it. Buy the celestron astromaster 70az telescope, take it outside on a clear night, point it at whatever’s brightest, and look. Everything else follows from that moment.
