3. Two Eyepieces (25 mm & 10 mm) for Variable Magnification Power
The telescope comes bundled with 25 mm and 10 mm eyepieces, allowing you to switch easily between wide-angle and high-magnification views. The 25 mm eyepiece offers broader, immersive visuals—ideal for exploring the Milky Way or viewing large star fields—while the 10 mm eyepiece zooms in for finer planetary details like Mars’ polar caps or the craters of the Moon. With a standard 1.25″ barrel, both eyepieces deliver crisp optics and are compatible with a wide range of aftermarket lenses and filters to grow your observing experience.

4. 6×30 Optical Finderscope for Efficient Target Alignment
Included with the telescope is a 6×30 optical finderscope, which provides a clear, magnified view to help you quickly locate and center celestial objects. Once aligned with the main telescope, the finderscope becomes your fast-track tool for navigating the sky. Whether you’re scanning for a bright planet or tracking down a faint star cluster, the finderscope simplifies your experience—especially under low-light conditions. Its optical clarity, compact size, and intuitive use make it a reliable asset for both beginners and more advanced stargazers.

5. Heavy-Duty Steel Tripod with Reinforced Accessory Tray
Supporting the telescope is a full-sized, adjustable steel tripod, offering maximum stability across a variety of terrain and viewing angles. Its integrated accessory tray not only stores your eyepieces and tools within arm’s reach but also locks the tripod legs in place for added rigidity. The tripod’s design makes it easy to set up in your backyard or transport to a darker site. With minimal vibration and strong structural balance, you can enjoy uninterrupted observing sessions without dealing with wobbles or instability, even at high magnification.

How to Use

1. Prepare the Tripod and Mount Carefully
Place the heavy-duty tripod on a flat surface and fully spread the legs for balance. Attach the EQ4 equatorial mount on top and tighten all screws using your hands. Ensure everything feels firm, as this mount supports a large optical tube and needs perfect stability before adding any accessories.

2. Mount the Refractor Tube Securely
Hold the 127mm telescope tube firmly and slide it into the dovetail slot on the EQ4 mount. Once it’s positioned, tighten the knob so the tube doesn’t shift during movement. Make sure the tube is balanced so it doesn’t lean forward or backward when adjusting directions.

3. Calibrate the Finder Scope Properly
During the day, choose a distant object like a pole or hill. Align it through the main eyepiece and then adjust the 6×30 finder scope until the same object is visible in its center crosshairs. This step ensures accurate targeting of celestial objects later at night.

4. Select and Insert the Right Eyepiece
Start with the 25mm eyepiece for wider views like the Moon or star clusters. Then try the 10mm eyepiece for closer looks at planets or lunar details. You can also add a 2x Barlow lens for higher magnification. Always focus slowly using the rack-and-pinion knob for best clarity.

5. Track Celestial Motion Smoothly
After polar aligning the EQ4 mount with the North Star (Polaris), use the slow-motion control knobs on both the right ascension and declination axes. This helps you follow stars, planets, or the Moon as they move across the sky without losing sight in the eyepiece.

How to Take Care

1. Clean the Objective Lens with Precision
The large front lens collects light and also dust, so use a soft blower first, then wipe with a microfiber cloth in circular motion. Never use paper, cloths with lint, or random cleaning sprays, as they can leave marks or damage the coating.

2. Avoid Letting Moisture Stay on It
If you’ve used the telescope at night and there’s dew or moisture, never close it immediately. Leave it uncovered indoors for a few hours to let all moisture evaporate naturally. Covering it too early can lead to fungus or fog on internal glass surfaces.

3. Use Padded Storage for Transportation
If you move the telescope from one location to another, pack it in a padded hard case or foam-lined bag. This protects the mount, tube, and lenses from bumps, vibrations, or accidental drops during travel.

4. Recheck Balancing Before Every Session
Since the telescope is large and heavy, the mount balance may shift over time. Before each stargazing session, recheck the weight distribution and make sure both axes move freely without falling forward or backward.

5. Store in Cool and Dust-Free Spaces
Keep the telescope indoors away from windows or places with extreme temperature changes. Avoid garages, attics, or basements where dust, insects, or dampness can slowly damage the optics or metal parts of the mount.

Safety Tips

1. Never Observe the Sun Without Solar Filters
This telescope gathers a lot of light, and looking at the sun without a full-aperture solar filter is extremely dangerous. Always use a certified solar filter that fits over the front lens—not just over the eyepiece—or permanent eye damage can occur.

2. Ensure Tripod Stability on All Surfaces
The EQ4 mount is heavy, so place the tripod only on flat, hard surfaces like concrete or tiled floors. Using it on uneven or sloped ground increases the risk of tipping, which could damage the telescope or cause injury.

3. Allow Only Supervised Use by Beginners
Because of its weight and complexity, beginners or kids should never use this telescope alone. Always have a responsible person present to help with alignment, focusing, and adjusting the heavy equatorial head safely.

4. Avoid Adjusting Internal Optical Parts
Do not attempt to open or realign the objective lens or the focuser assembly unless you are experienced. Wrong adjustments may permanently misalign the light path and reduce the sharpness of the images.

5. Don’t Leave It Unattended Outdoors
Even for short breaks, avoid leaving the telescope unattended in open spaces. Sudden wind, rain, or insects can cause problems, and long sun exposure can damage the paint, seals, or optics over time.
