FAQs

What is the best way to start using this telescope?

Begin by setting it up in a clear area. Use the finder scope to aim at a bright, distant object like the Moon or a faraway tree. Once centered in the finder, look through the main telescope and adjust the focuser until the image is sharp.

Can I use this telescope during the day?

Yes, the diagonal prism provides an upright image, making it suitable for terrestrial viewing, such as observing wildlife or distant landscapes.

What types of celestial objects can I see?

You can observe the Moon in great detail, Jupiter and its four largest moons, Saturn's rings, brighter star clusters, and some brighter nebulae.

How do I take pictures with the smartphone adapter?

Attach the adapter to the eyepiece, then secure your smartphone. Center your phone's camera lens over the adapter's eyepiece and take photos as you normally would.

What is the warranty on this telescope?

The OYS telescope comes with a lifetime warranty against manufacturing defects.

Is this telescope suitable for a complete beginner?

Absolutely. It's designed with beginners in mind, featuring easy setup and intuitive controls.

How much magnification can I achieve?

With the included eyepieces, you can achieve 20X (K20mm) and 44X (K9mm) magnification.

Troubleshooting

Blurry images

Ensure the focuser knob is adjusted correctly. Check that the eyepiece is securely inserted. Clean the eyepiece and objective lens if they appear dirty.

Difficulty locating objects

Properly align the 5x24 finder scope with the main telescope. Practice using the finder scope to center your target before looking through the main eyepiece.

Telescope is shaky

Ensure the tripod legs are fully extended and locked. Place the tripod on a stable, level surface. Avoid touching the telescope or tripod while observing.

Smartphone adapter not holding phone securely

Adjust the clamp mechanism to fit your phone's dimensions. Ensure the phone is positioned centrally over the adapter's eyepiece for optimal image capture.
