Celestron Astromaster 70az Lt Refractor Telescope Kit: A Practical Guide (2026)

Updated November 2026

The celestron astromaster 70az lt refractor telescope kit is a small, portable refractor that shows the Moon’s craters, Jupiter’s cloud bands and Saturn’s rings when used correctly. This guide walks you through assembly, the first night of observing, and the adjustments that make the biggest difference to what you see. Expect to be observing within about 20 minutes of opening the box.

What the 70AZ LT Kit Can Realistically Show

A 70 mm refractor gathers far more light than your eyes alone, but it is a modest instrument. Bright targets look best: the Moon at any phase, Jupiter and its four largest moons, Saturn’s rings, Venus’s phases, and the brighter star clusters such as the Pleiades. Faint galaxies and nebulae will appear as dim, grayish patches rather than the colorful images in photographs. Setting that expectation early prevents disappointment.

Step-by-Step Setup for the First Night

1. Place the tripod on firm, level ground. Extend the legs to a height that puts the eyepiece near your standing eye level, and tighten the leg locks evenly.
2. Attach the mount head to the tripod and secure the center bolt. Snug is enough; overtightening can strip the threads.
3. Slide the optical tube onto the altazimuth mount and tighten the clamps on both axes so the scope moves smoothly without drifting.
4. Insert the lowest-power eyepiece into the diagonal, then insert the diagonal into the focuser and tighten the thumbscrew.
5. Point the scope at a distant daytime object, never the Sun, and rotate the focus knob until the image is sharp.
6. After dark, aim at a bright, easy target such as the Moon, and center it in the finderscope before looking through the eyepiece.

Aligning the Finderscope

Center a distant terrestrial object or a bright star in the eyepiece first, then adjust the finderscope’s alignment screws until the same object sits centered in its crosshairs. Do this in daylight if you can. Once aligned, the finder becomes your main tool for locating targets quickly.

Choosing Eyepieces and Using Magnification

The kit’s included eyepieces give you a usable range, but magnification is not the goal. Higher power makes the image dimmer and more sensitive to shaking. A practical rule is to start low, then increase power only if the image stays steady and bright. Many owners find that the Moon and Jupiter respond well to moderate power, while deep-sky objects look better at lower power with a wider field.

Target	Suggested Starting Power	What to Look For
Moon	Low to medium	Crater edges, terminator shadows
Jupiter	Medium	Cloud bands, Galilean moons
Saturn	Medium	Rings and the Cassini Division at steady seeing
Open clusters	Low	Star groupings, color differences

Common Mistakes and Tips

• Never point the scope at the Sun without a proper full-aperture solar filter. Eyepiece filters and sunglasses are not safe.
• Let the scope reach outdoor temperature for 15 to 30 minutes before judging detail, since a warm tube creates shimmer.
• Avoid observing over rooftops or hot pavement, where rising air blurs the image.
• Focus carefully on each eyepiece change, because focus shifts slightly between them.
• Keep your observing sessions short at first; eye fatigue makes it harder to see fine detail.

Recommended Gear

• A red-light flashlight preserves your dark adaptation while you read star charts and adjust the mount. View on Amazon
• A planisphere or star chart app helps you locate targets without guessing. View on Amazon
• A Moon filter reduces glare when the Moon is near full and makes surface detail easier to see. View on Amazon

FAQ

Can the celestron astromaster 70az lt refractor telescope kit show planets?

Yes, Jupiter’s cloud bands, its four largest moons and Saturn’s rings are visible at moderate power on steady nights. Planets will look small and require patience.

Do I need to buy extra eyepieces?

Not necessarily. Start with the included eyepieces and add others only if you find a specific magnification you need.

Is this kit suitable for deep-sky photography?

It is better suited to visual observing of bright targets. Deep-sky astrophotography usually requires a camera adapter and longer exposures than this kit is designed for.

Conclusion

With careful setup, a finderscope alignment and modest magnification, the celestron astromaster 70az lt refractor telescope kit rewards you with clear views of the Moon and planets. Start with bright targets, keep expectations realistic, and build your skills one night at a time. Patience at the eyepiece matters more than any accessory.
