Product description The Celestron Cometron FirstScope 76mm f/4 Alt-Az Reflector Telescope is designed as an ideal entry-level optic for observing the Moon and planets, comet-watching, and enjoying meteor showers. This tabletop telescope features a Newtonian reflector optical design whose mirror is coated with a highly reflective combination of aluminum with SiO2 to improve resolution and contrast, while reducing comas and color fringing. The scope comes with two fully multi-coated 1.25" diameter eyepieces that yield 15x and 30x magnifications. The manual tabletop alt-azimuth mount gives you easy control of the telescope for tracking near and deep-sky objects. This telescope is easy to assemble and transport, so you can spend less time setting up and more time enjoying the night sky. - Optical Performance
