Model: 80-51050 | Brand: Explore Scientific

Introducció

This manual provides essential information for the proper setup, operation, and maintenance of your National Geographic 50mm Refractor Telescope. Designed for beginners and young explorers, this telescope offers inspiring views of celestial objects like the Moon and bright star clusters, as well as terrestrial observations.

Informació de seguretat

WARNING: Never look directly at the sun through your telescope or its finder scope, even for an instant, without a professionally made solar filter that completely covers the front of the instrument. Permanent and irreversible eye damage may result. Always supervise children using the telescope during daylight hours.

When observing terrestrial objects, be aware that images will appear flipped right to left, as is common with refractor telescopes due to the nature of their optics.

3. Canvi d'augment

To change the magnification, simply remove the currently installed eyepiece and replace it with the other one. Start with the lower magnification (20mm eyepiece) to locate objects, then switch to the higher magnification (12.5mm eyepiece) for a more detailed view.

4. Terrestrial vs. Astronomical Viewing

This telescope is suitable for both astronomical observations (Moon, bright planets, star clusters) and terrestrial viewing (nature, distant landscapes). Remember that terrestrial images will appear horizontally flipped.
