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 150mm parabolic primary mirror and a compact, manual azimuth mount, the Heritage 150 is the perfect blend of portability and aperture, just as Newton intended. Collecting 363% more light than the human eye and 44% more light than the 130mm model, the Heritage 150 uses the same optics as our Classic 150P Dobsonian, but at a fraction of the size and cost. Each mirror is constructed of durable borosilicate glass with our signature Radiant™ Aluminum Quartz (RAQ™)coating. The optical tube uses a unique system that allows it to be collapsed for easy portability and storage while retaining collimation. If you’re looking for a grab-and-go travel telescope that delivers a bold, full size viewing experience, look no further than the Heritage 150. Its lightweight azimuth base uses Teflon™ bearings for smooth, accurate slewing and has an altitude locking knob for steady viewing. The base also features skid resistant, vibration suppressing rubber feet, offering a stabilized view while allowing the telescope to be setup virtually anywhere with minimal vibration, making this telescope the perfect camping companion.
