The Cometron FirstScope Reflector Telescope from Celestron is a table-top telescope featuring a Newtonian reflector optical design. The 3" objective mirror and 300mm focal length make this beginner telescope suitable for lunar, planetary and even deep-space viewing.

The telescope comes with two fully multicoated 1.25" diameter Kellner eyepieces. The 10mm eyepiece provides a high 30x magnification, while the 20mm produces 15x magnification. These two eyepieces offer a range of viewing options depending on what you are looking at.

A 5x24 finderscope has a wide field of view that helps find what you're looking for and gets you viewing faster. The table-top alt-azimuth mount gives you easy control of the telescope for tracking slow objects like nebulae or fast moving subjects like comets. This telescope is easy to assemble and transport, so you can spend less time setting up and more time enjoying the night sky.
