The Skywatcher Evostar 80ED is an apochromatic doublet that offers high performance for visual observers and astrophotographers. The objective lens features an element made by FLP 53 Ohara (Japan), the finest extra-low dispersion glass (ED) that minimizes the chromatic aberration for the best colour correction. As a result, planets and the moon are sharp at high magnification and in astrophotography, images have a high contrast as stars are not surrounded by the purple halo due to chromatic aberration. 

The 2" Crayford focuser is solid, precise and backlash free. It operates at two speeds due to the 10:1 reduction mechanism for an extra fine focusing adjustment, which is paramount for astrophotography and high resolution observations.

The objective lens is fully multi coated with the Skywatcher proprietary "Metallic High-Transmission Coating" (MHC) for an effective anti-reflection result that approaches a transmission of 99.5%.

The aluminium tube is light-baffled and blackened to ensure high contrast absorbing stray light.

The Evostar 80 ED is an excellent telescope for astrophotography. Its chromatic correction is the highest of all the other Evostar telescopes and its small dimension and affordable price makes this telescope the best entry level apochromatic refractor for astrophotographers. 

Its sharpness and colour correction makes this telescope ideal for sun and moon eclipses and sun observations (with a full aperture filter) especially with a Barlow lens to increase the focal length.
