Also called Newtonians, these telescopes are the best aperture-bang for the buck.
Also called Newtonians, these telescopes are the best aperture-bang for the buck. They have fat tubes with a parabolic mirror at the bottom. Light from the sky enters the tube and gets reflected by this mirror back up to the top of the tube where there is a small diagonal mirror that bounces the light out the side of the tube to your eye. The mirrors are cheaper to manufacture than refractor lenses, so you can afford a much larger diameter telescope when you choose this style. With all of this extra aperture, you will be able to see dim and distant objects in the deep­-sky. We think the Celestron StarSense Explorer 8" is an unbelievable deal. You won’t believe what you will be able to see with such a modest investment!
