Statement from Alex Martin, Executive Director of Sidewalk Science Center:
"Celestron's NexStar 4SE was a hidden gem. Despite its size, its magnification is comparable to that of our largest telescope, Celestron's Evolution 9.25. Coming in at 1/4 the cost, the 4SE is wonderful for beginners who want to try out motorized telescopes. Best of all, it's lightweight - only 20 pounds - and sets up in under 10 minutes. You'll keep this one for a decade or more."
Description:
- Celestron’s iconic “orange tube” design is updated with all the latest features to provide the best stargazing experience for beginners and experienced observers alike.
- 4-inch aperture provides excellent light-gathering ability at an affordable price. You’ll get impressive views of the Moon and planets, along with deep sky objects like the Orion Nebula, while retaining a compact form factor.
- Fully automated GoTo mount with database of 40,000+ celestial objects automatically locates and tracks objects for you.
- SkyAlign technology gets your telescope aligned and ready to observe in minutes. Even if you’re unfamiliar with the night sky, you can easily align your telescope on any three bright objects.
- Unique single fork arm design and sturdy steel tripod all break down into separate components for easy transport and quick assembly.
