In 1668, Sir Isaac Newton invented the first reflector telescope. By using mirrors instead of optical lenses, Newton was able to increase the aperture of his telescope while reducing the overall size of the tube, leading to brighter views of the night sky. The Heritage 130 pays homage to this design by honoring some of the great astronomers throughout history: Galileo, Messier, Kepler, Newton, among others. By using a lightweight 130mm parabolic primary mirror and a smooth, manual azimuth mount, this telescope is the perfect blend of portability and aperture, just as Newton intended.

Collecting 319 times more light than the human eye, this a powerful tabletop Dobsonian, capable of delivering stunning views of planets, galaxies and nebulae while remaining affordable. 

Its lightweight azimuth base uses Teflon bearing for smooth, accurate slewing and has an altitude locking knob for steady viewing. The base also features skid resistant, vibration suppressing rubber feet, which minimizes vibration while allowing the telescope to be setup virtually anywhere with minimal vibration, making this telescope the perfect camping companion.
