Skywatcher Evostar 100EDX

100MM (4″) F/700 ED APOCHROMATIC REFRACTOR TELESCOPE

The Sky-Watcher Evostar-100ED apochromatic doublet refractor has undergone some fantastic improvements. We are pleased to introduce the new Evostar-100EDX model, which has received a number of very useful mechanical improvements. In addition, the focal ratio has been improved from f/9 to a more photo-friendly f/7. It comes in a beautiful white/green finish. The Evostar-100EDX is an excellent instrument for both visual observation and photographic use with all the necessary accessories.

The new Evostar-100EDX is now equipped with an enlarged 2.8″ focuser with scale, which has a 360° rotatable adapter, as well as a retractable dew cap and a solid handle.

It contains a new f/7 optical system, which includes a lens made from premium Japanese Ohara FPL-53 ED glass, which eliminates visible chromatic aberration. A matching 0.92x Focal Reducer / Field Flattener (20332) is optionally available for photography.

The optics deliver razor-sharp stars with a pitch-black, high-contrast sky background. Each glass-to-air surface is coated with an exotic metallic coating that provides an impressive 99.5% light transmission. Sky-Watcher’s proprietary Metallic High-Transmision Coatings (MHTC) are among the finest anti-reflective coatings in their class.

Apochromatic refractors, with their unobstructed, picture-book diffraction figures, produce the sharpest, highest quality optical image possible for this aperture of any optical system available.

For a long time, the Evostar-ED Doublets have been the best choice of photographic refractors for many astrophotographers, due to their combination of excellent imaging performance and low price. Due to the use of less glass in their construction, they are usually lighter and therefore more comfortable to transport than comparable triplet or other multi-lens ED refractors with this aperture.
