Why Choose the Esprit 100EDX?
Premium Package


This fully equipped telescope helps users get started quickly. Included mounting rings, camera angle adjuster, large D-style dovetail, and a hard carrying case for secure transport and storage. These practical accessories are designed move from home setup to dark-sky destination with confidence.
Versatile Companion


Striking the perfect balance for modern strainwave mounts like the Wave 150i by offering a 100mm aperture creating bright images without requiring heavy mount heads and cumbersome counterweights. Its compact 16-lb frame and fast f/5.5 optical system create a stable combination that serves as the ultimate powerhouse for high-quality, destination astrophotography.
*Mounts, tripods, and other accessories imaged are sold separately
Dual-Speed Focuser


The Esprit 100EDX is equipped with a 3.4-inch dual-speed linear power focuser. This robust design provides smooth, precise focusing with the stability needed to support cameras and imaging accessories. The focuser is engineered to maintain alignment while allowing critical fine-focus adjustments, helping you capture pinpoint stars and repeatable results session after session.


True Super-APO Triplet Performance
The Esprit 100EDX solves this by utilizing an advanced, three-element air-spaced triplet design. By introducing a third laboratory-matched lens made from premium Japanese Hoya FCD-100 extra-low dispersion (ED) glass, the optical path can correct and align red, green, and blue light waves at once.
While standard doublet telescopes use two lens elements to focus light, they often struggle to bring all wavelengths of the color spectrum to the exact same focal point. This results in chromatic aberration, or artificial color around your target or interest.


Effortless Framing & Solid Support
The Esprit 100EDX streamlines your night under the stars with built-in hardware upgrades. At the rear sits an integrated Camera Angle Adjuster, allowing you to smoothly rotate your entire imaging train a full 360°. This means you can perfectly square up your target and frame your shot without loosening your adapters or throwing off your precise focus. Supporting the optical tube is a dual-purpose D-style dovetail bar coupled with a rigid tube rings and integrated carry handle.


Metallic High-Transmission Coatings
The Esprit optical design uses a laboratory-matched triplet lens system to deliver pinpoint stars, rich contrast, and beautifully dark backgrounds that make your favorite targets stand out. Premium FCD-100 extra-low dispersion (ED) glass elements paired with Sky-Watcher’s proprietary Metallic High-Transmission Coatings (MHTC™) help virtually eliminate false color while maximizing light transmission, brightness, and clarity. Internal knife-edge baffling keeps stray light and reflections in check for cleaner views and razor-sharp astrophotos. Wrapped in a beautifully crafted aluminum tube with a striking white finish, the Esprit EDX looks every bit as impressive as the professional wide-field views it delivers.
