OTA ONLY - Mount and Tripod Required

Designed and built primarily for lunar and planetary views with the ability to resolve bright deep-sky objects like clusters, the Explore Scientific FirstLight 102mm f/9.8 Refractor Telescope is fully multi-coated with anti-reflection coatings to reduce light loss and produce brighter and clearer images with more accurate colours versus non-coated systems.


Offered here without a mount or tripod, this version of the FL 102mm is ideal for users who already have a reliable support system and are looking to add to their observation arsenal, or for those building an a la carte rig. Explore Scientific includes several accessories, including a 25mm eyepiece that yields 40x, 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.
