ED152 Air-Spaced Triplet Telescope in Carbon Fiber by Explore Scientific

Overview of Explore Scientific ED152 Air-Spaced Triplet Telescope in Carbon Fiber Description Observing with the ED152 Air-Spaced Triplet FCD1 Series Apochromatic Refractor in Carbon Fiber with genuine HOYA FCD1 ED Glass: Serious amateur astronomers who choose apochromatic refractors know that generally once you start using an instrument larger than 127mm, that the limitation of size and weight can become a problem, often requiring a larger-class equatorial mount that is expensive and heavy. For some, large and heavy telescopes and mounts are out of the question due to physical constraints. With the Explore Scientific ED152 at only 20.5 lbs, many mid-priced, lighter, and more portable equatorial mounts (such as the precision Losmandy G11 PMC-Eight) are perfectly matched with this optical tube assembly for high quality astrophotography and serious visual use. With its 44% increase in light grasp and image brightness compared to the ED127 Air-Spaced Triplet, and 125% increase compared to the ED102 Air-Spaced Triplet, the ED152 Air-Spaced Triplet FCD1 Series in Carbon Fiber is a research-class instrument, ready for high-productivity assignments. Observe moon transits with their shadows across the face of Jupiter, as well as structural detail and color variations within the wake of the Great Red Spot and at the boundaries of numerous equatorial cloud belts; resolve Cassini’s and Enke’s Divisions of Saturn’s rings and substructures within the rings themselves. Nebulae and galaxies objects appear like they are etched in crystal” some describe it as “three-dimensional” against a very dark sky because of the telescope’s unobstructed, high contrast optical system. Nebulae stand out in splendid detail, giving one the impression they are looking through a much larger aperture telescope, with filamentary structures observable even under less than optimal seeing conditions. A wide range of accessories is available to suit virtually any observing requirement. For the school or university observatory, or to add to the collection of instruments for the dedicated amateur astronomer, the ED152 Air-Spaced Triplet FCD1 Series in Carbon Fiber is a true work-horse optical instrument ready for any observing or imaging requirement.

It features a triplet lens system that provides clear and crisp images, making it ideal for astrophotography and deep space observations. The lens system is air-spaced, which means that the lenses are held apart by air to reduce the effects of thermal expansion and contraction, resulting in sharp images even in changing temperatures. The lens is made of premium extra-low dispersion (ED) glass, which minimizes chromatic aberration and produces accurately colored images. The telescope is constructed with a carbon fiber tube, which is lightweight and durable. The carbon fiber material provides excellent thermal stability and prevents the tube from expanding or contracting due to temperature changes, keeping the lens in perfect alignment. The telescope comes with a 3-inch dual-speed rack and pinion focuser that ensures precise focusing of images, and an easy-to-adjust collimation system for maintaining the alignment of the lenses. The Explore Scientific ED152 Air-Spaced Triplet Telescope in Carbon Fiber is a versatile telescope that can be used for various applications, including planetary and deep-sky observations. It is compatible with many different eyepieces and accessories, allowing you to customize your viewing experience. Whether you're a professional astronomer or an amateur enthusiast, this telescope is an excellent investment that will provide you with years of viewing pleasure.
