Sky-Watcher EVOSTAR-100EDX: Apochromatic Refractor Telescope

Sky-Watcher EVOSTAR-100EDX: Apochromatic Refractor Telescope

 The Sky-Watcher EVOSTAR-100EDX apochromatic doublet refractor is a superb instrument for both astrophotography and visual observing. This updated model features significant mechanical and optical improvements, making it a powerful and versatile tool for astronomers of all levels.

Key Features:

•  Faster f/7 Focal Ratio: The new EVOSTAR-100EDX features a faster f/7 focal ratio (updated from f/9), making it more efficient and imaging-friendly.

• Premium ED Glass: The matched optics include a premium Japanese Ohara FPL-53 ED glass lens element. This high-quality glass virtually eliminates chromatic aberration, ensuring sharp, color-free images with excellent contrast.

• Enhanced 2.8” Focuser: A redesigned 2.8” indexed focuser with a built-in 360° rotator provides smooth, precise focusing, making it easier to achieve perfect alignment for your shots.

• High-Transmission Coatings: Every air-to-glass lens surface is treated with proprietary Sky-Watcher “Metallic High-Transmission Coatings” (MHTC). These exotic anti-reflection coatings ensure a light throughput of approaching 99.5%, delivering bright, high-contrast views.

• Astrophotography Ready: The EVOSTAR-100EDX excels at capturing stunning astrophotography images. Its unobstructed diffraction patterns produce tack-sharp stars against a charcoal-black, contrast-rich sky.

• Lightweight and Portable: Thanks to its doublet design, this refractor is lighter and more convenient to handle than many triplet or multi-element refractors of similar aperture.

• Convenient Design: The telescope also includes a retractable dew shield and a handy carrying handle for easy transport and setup. 

Unmatched Performance and Versatility

 The EVOSTAR-100EDX continues the legacy of its predecessors, which have long been a favorite among astrophotographers for their exceptional performance and affordability. Its apochromatic design and high-quality components make it an ideal choice for capturing stunning deep-sky images while also providing crisp, high-quality views of planets and other celestial objects.

Please note: The EVOSTAR-100EDX is supplied without an eyepiece, star diagonal, or finderscope. For enhanced imaging, an optional 0.92x Focal Reducer/Field Flattener (code 20332) is available separately.
