The Celestron® StarSense Explorer DX 130 Reflector Telescope combines smartphone technology with precision optics to make astronomy accessible for all learners.Â
This innovative telescope uses the StarSense app to analyze the night sky in real time, guiding users to planets, nebulae, and stars without prior experience. In just minutes, students can align the telescope, select celestial objects, and navigate using on-screen arrows and a green bullseye indicator. The large 130 mm reflector captures bright, detailed views of deep-space objects, helping students explore light, motion, and the structure of the universe through hands-on observation.
The entire kit weighs just 18 pounds, so it’s perfectly portable and easy to bring to any observation site.

Note: 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 buildup can damage the optic and any accessories attached to it.
