SkyWatcher 100mm ESPRIT ED Triplet APO Refractor Telescope

SkyWatcher 100mm ESPRIT ED Triplet APO Refractor Telescope Designed with the discerning astrophotographer in mind, the SkyWatcher 100mm ESPRIT ED Triplet APO Refractor Telescope delivers the kind of imaging performance one would expect from telescopes costing thousands of dollars more. This premium telescope features a high-quality ED (Extra-low Dispersion) triplet lens configuration that ensures superior color correction and minimal chromatic aberration, providing you with crisp, clear, and true-to-life images of the night sky. The Esprit’s three-element, air-spaced objective lens design virtually eliminates false color, yielding exceptional contrast and sharpness. Each element is fully multi-coated with SkyWatcher’s proprietary Metallic High-Transmission Coatings™ (MHTC), producing a transmission rate that rivals any refractor on the market. With a 100mm aperture and 550mm focal length, this telescope is ideal for capturing detailed and wide-field images of celestial objects, from the intricate structure of distant galaxies to the delicate features of nebulae and star clusters. The fully multi-coated optics maximize light transmission, ensuring bright and sharp views even in low-light conditions. The SkyWatcher 100mm ESPRIT ED also features exclusive dual-speed, Helinear track focusers, which provide smooth, rock-solid focusing with zero image shift. Using a captain’s wheel design, all focusers can be rotated, giving astrophotographers flexibility when framing their image. The advanced 3.4” dual-speed rack and pinion focuser allows for precise and smooth adjustments, essential for achieving perfect focus in your astrophotography sessions. SkyWatcher supplies everything you need to get out under the stars, including a 2-element field corrector, which guarantees a flat field across the entire imaging plane. Additionally, the telescope comes equipped with an 8×50 right-angle correct image finder scope, a 2” dielectric diagonal, an M48 camera adapter, and sturdy tube rings with a D-rail for secure mounting. The robust aluminum optical tube assembly (OTA) is designed for durability and portability, with a retractable dew shield and lightweight construction that makes it easy to transport and set up. The included padded aluminum carrying case ensures that your telescope and accessories are protected during transport and storage. Whether you’re a seasoned astrophotographer or an enthusiast looking to take your celestial imaging to the next level, the SkyWatcher 100mm ESPRIT ED Triplet APO Refractor Telescope offers the perfect combination of performance, quality, and convenience. Capture the wonders of the universe in stunning detail and clarity with this exceptional piece of astronomical equipment.
