The Cometron FirstScope 76 is a compact, lightweight tabletop Dobsonian-style reflector designed for beginners and casual astronomers seeking their first telescope experience. This Newtonian reflector features a 76mm aperture and 300mm focal length with a fast f/3.95 ratio, delivering bright, sharp views of the Moon, planets, comets, and deep-sky objects like the Orion Nebula with a wide field of view. The fully assembled telescope comes with two Kellner eyepieces (20mm and 10mm), a 5x24 finderscope, and a simple manual altazimuth mount, making it an ideal grab-and-go instrument for spur-of-the-moment observing sessions.
