Celestron AstroMaster 102AZ Telescope

The Celestron AstroMaster 102AZ is a wonderfully versatile telescope for anyone who wants to enjoy the world around them during the day and still have a real astronomical telescope when night arrives.

Its generous 102mm refractor optics and relatively short 660mm focal length give you a bright, comfortably broad view that works beautifully across harbours, lakes, countryside and mountain landscapes.

Rather than simply looking at the view, you can start exploring it. Follow boats moving across distant water, examine landmarks on another shoreline, study mountain features or watch wildlife that would otherwise be too far away to appreciate properly.

The supplied 20mm and 10mm eyepieces give 33x and 66x magnification — a particularly useful range for terrestrial viewing. The lower power makes it easy to scan a larger area and locate something interesting, while 66x lets you move closer when conditions allow.

The 90° erect-image diagonal ensures the view remains correctly orientated for daytime use, while the manual pan-handle mount makes pointing the telescope intuitive. A full-height steel tripod gives the AstroMaster a substantial observing platform whether it is set up on a deck, patio or out under the stars.

After dark, the 102mm aperture gives the telescope an entirely different personality.

The Moon reveals crater walls, mountains and dramatic shadows. Saturn's rings are unmistakable, Jupiter's four bright moons can be followed from night to night, and star clusters reveal attractive fields of individual stars. Bright nebulae and double stars provide even more to discover.

The AstroMaster 102AZ is the kind of telescope you can buy because you have a wonderful daytime view — and then discover that you've also brought home an entirely new way to enjoy the night sky.

Why Choose the Celestron AstroMaster 102AZ?

• 102mm refractor optics — bright, detailed views for both terrestrial and astronomical observing.
• Excellent day-and-night versatility — explore landscapes, boats, mountains and wildlife, then turn to the Moon, planets and stars.
• Broad 660mm focal length — makes scanning scenery and larger night-sky targets easy and enjoyable.
• 33x and 66x supplied — practical magnifications for finding subjects and moving in for closer views.
• Can I add other eyepieces later?
  Yes. The supplied eyepieces are only the starting point. Additional 1.25" eyepieces or a suitable Barlow lens can extend the telescope's magnification range as you discover the kinds of daytime and night-sky viewing you enjoy most.
• 90° erect-image diagonal — provides a correctly orientated view for daytime use.
• Simple pan-handle control — intuitive pointing without complicated controls or alignment.
• Full-height steel tripod — a substantial platform for comfortable observing.
• 102mm astronomy capability — see Saturn's rings, Jupiter and its moons, detailed lunar landscapes and bright star clusters.
• Red-dot finder — helps locate both terrestrial and astronomical targets.
• 2-year Celestron warranty.

Make More of the View

If your home overlooks water, mountains or an expansive landscape, the AstroMaster 102AZ gives you a reason to keep coming back to that view.

At 33x, a harbour becomes a landscape you can explore rather than simply look across. Boats can be followed as they move through the water, distant coastlines reveal new features and mountain faces begin to show structure that cannot be appreciated with the naked eye.

Switch to 66x when you want a closer look.

That combination of a 102mm objective and moderate magnification is particularly useful because daytime viewing is often about balancing detail with atmospheric conditions. On a clear, still morning, distant detail can be remarkable; on a warm afternoon, heat shimmer may make the wider lower-power view more satisfying.

After Dark, Keep Exploring

When the Sun goes down, the AstroMaster becomes a genuine astronomical telescope.

The Moon can absorb an entire evening as sunlight picks out crater rims, mountain ranges and long shadows across the surface.

Saturn's rings are clearly visible, while Jupiter reveals its four major moons and can show its main cloud belts under good conditions.

Open star clusters suit the telescope's relatively broad field especially well, revealing attractive groups of stars against the darker background of the sky. Bright nebulae, double stars and other easily observed targets add more variety throughout the year.

Simple Enough to Use Whenever the View Calls

There are no motors, batteries or alignment routines.

The AstroMaster's alt-azimuth mount works in the same intuitive directions you naturally look — up, down and around the horizon.

Use the pan handle to move across a landscape or towards a night-sky target, then focus until the detail snaps into view.

That simplicity matters in a telescope designed to be enjoyed regularly rather than saved for special occasions.
