Designed and built for beginners or as a competent grab-and-go option for fast observation sessions, the Explore Scientific FirstLight 127mm f/9.4 Alt-Az Refractor Telescope offers a simple yet powerful observation rig for viewing the Moon, planets, meteor showers, and bright deep-sky objects. The optics are fully multicoated with anti-reflection coatings to reduce light loss and produce brighter and clearer images with more accurate colors versus non-coated systems.

The scope features a manual alt-azimuth mount with dual-axis control cables that allow users to track objects as they move across the night sky. Its aluminum tripod provides a stable observation platform, and its adjustable height from 38.5 to 55.5" allows for comfortable viewing by most users. Explore Scientific includes several observational accessories including a 25mm eyepiece that yields 48x, a 90° star diagonal to put the user's head in a comfortable viewing angle, a universal smartphone eyepiece adapter for easy astrophotography, and a wide-field unmagnified red-dot finderscope.
