Sky-Watcher EDX 100 Super APO Triplet f/5.5 Telescope

Premium FPL-53 Glass and Knife-Edge Baffles

The optical design of the 100mm model is built around a Japanese Ohara FPL-53 glass element. This high-index glass is the industry standard for minimizing chromatic aberration, allowing for pinpoint, color-free stars across the entire field.

To further enhance contrast, the interior of the tube is equipped with a series of knife-edge baffles. These precision-placed baffles suppress stray light reflections, ensuring that your images have the jet-black background required for professional-grade astronomical data.

Massive 3.4-inch Linear-Track Focuser

Unlike standard refractors, the Esprit EDX 100 features an overbuilt 3.4-inch linear-track rack-and-pinion focusing system. This exclusive design provides a rock-solid platform that completely eliminates image shift during critical focusing.

• Heavy Payload Support: The 3.4-inch drawtube is designed to support heavy imaging trains, including large-format cooled CMOS cameras and filter wheels, without flexure.
• Micro Focus Control: A dual-speed 11:1 micro-focus knob allows for the extreme precision needed to find the perfect focal point with high-resolution sensors.
• Integrated Rotator: The focuser assembly allows for effortless rotation of the camera to ensure your target is framed perfectly every time.

Professional Grade Imaging

With a focal length of 840mm and a native f-ratio of f/8.4, the Esprit EDX 100 is ideal for medium-sized nebulae and galaxy clusters. For those using full-frame sensors, an optional two-element field corrector is available to guarantee a flat field across the entire 44mm imaging plane. This combination of precision mechanics and elite optics makes it a staple for serious astrophotographers.
