FAQs
Is this telescope safe for viewing the sun?
Yes, this telescope includes a tested solar filter that must be securely attached to the front of the telescope *before* observing the sun. Never look at the sun through the telescope without the solar filter, as it can cause permanent eye damage.
Do I need to assemble the telescope?
No, the telescope comes completely pre-assembled and ready for immediate use. You only need to set up the tripod and mount the telescope tube.
What is the maximum magnification?
The telescope has a maximum magnification of 117x, achieved with specific eyepiece and Barlow lens combinations (if applicable, though none are specified beyond the included eyepiece).
Can I use my own eyepieces?
Yes, the telescope is compatible with standard 1.25-inch eyepieces, allowing you to expand your magnification options.
How do I record videos through the telescope?
Use the included smartphone adapter. Mount your smartphone securely in the adapter and align its camera lens with the telescope's eyepiece. Then, use your phone's camera app to record.
What kind of objects can I see with this telescope?
You can observe the Moon in detail, view Jupiter's moons and Saturn's rings, and safely observe the sun. It is also suitable for brighter star clusters and nebulae.
What is included in the package?
The package includes the telescope, a tripod, eyepieces, a finder scope, a smartphone adapter, a solar filter, astronomy software, and a downloadable moon map.
Troubleshooting
Image is blurry or out of focus.
Adjust the focuser knob slowly until the image becomes sharp. Ensure the correct eyepiece is inserted and that the protective lens caps have been removed.
Cannot find celestial objects.
Ensure the finder scope is aligned with the main telescope. Use the finder scope to locate the object first before looking through the main eyepiece. Start with brighter, larger objects like the Moon.
Smartphone adapter is unstable or camera doesn't align.
Adjust the mounting screws on the adapter to secure your smartphone firmly. Ensure the phone's camera lens is centered directly over the adapter's viewing port. Some phone cases may need to be removed for a secure fit.
Dim or unclear image during the day.
Ensure all lens caps are removed and the correct eyepiece is installed. For daytime terrestrial viewing, ensure the telescope is not pointed directly at the sun without the solar filter, which is only for solar observation.
Pros and Cons

Cons
- The azimuth mount may be less stable or precise for advanced astronomical tracking compared to equatorial mounts.
- The primary mirror size of 7.6 cm (76mm) is entry-level and may limit the detail visible in fainter deep-sky objects.
- Maximum magnification of 117x is suitable for the moon and planets but may not reveal fine details on distant galaxies.
- Requires careful alignment for optimal viewing, especially for solar observation.
