Premium Optical System

5 inch Schmidt-Cassegrain optical tube with StarBright XLT coatings and enough light gathering ability to view all the best celestial objects. With a large 5 inch Schmidt-Cassegrain optical tube, Celestron’s tried-and-true optical design for over 50 years, this telescope has enough light gathering ability to bring out impressive detail in celestial objects while remaining compact and lightweight. You can expect sharp, bright views of Jupiter’s four Galilean moons, its cloud bands and Great Red Spot, the rings of Saturn, the trapezium in the Orion Nebula, and the beautiful Pleaides Open Star Cluster. All air-to-glass surfaces are coated with our StarBright XLT optical coatings to visibly increase contrast and light transmission for brighter deep space views.

An ultra-stable altazimuth mount provides a sturdy foundation for StarSense Explorer DX. Slip clutches and geared slow motion controls in both axes help you move the telescope smoothly and zero in your target.

Solar Warning

Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result.

Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.

Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.
