Celestron StarSense Explorer LT 127AZ Smartphone App-Enabled Telescope

Finding your way around the night sky feels far more intuitive with the Celestron StarSense Explorer LT 127AZ, a Newtonian reflector telescope that pairs a 127mm aperture with a 1000mm focal length and a manual alt-azimuth mount. Built for beginners, it uses the StarSense Explorer smartphone app and dock to analyse star patterns overhead and guide the telescope towards visible celestial objects in real time.

The LT 127AZ combines app-enabled sky recognition with a straightforward manual mount, including altitude slow-motion adjustment via a sliding rod for finer tracking. Its 127mm (5-inch) optical tube gathers enough light for detailed views of bright planets, nebulae, star clusters and double stars, while the supplied 25mm and 10mm eyepieces, plus a 2x Barlow lens, give a useful range of magnifications straight from the outset. A full-height adjustable tripod and StarPointer red dot finderscope complete a well-rounded setup for home observing or taking to darker sites.
