The Cometron FirstScope provides bright, sharp views of comets and other celestial objects, and renders the Moon’s mountains and craters in crisp detail. And thanks to its wide field of view, you’ll be able to observe the brightest part of the comet and its tail or favorite deep-sky objects like the Orion Nebula.
