SKYWATCHER EVOSTAR 72 ED

The Skywatcher Evostar 72ED (also known as the Evoguide 72ED) is an apochromatic doublet refractor that offers high performance for visual observers and astrophotographers. The objective lens features extra-low dispersion glass (ED) that minimizes the chromatic aberration for excellent colour correction. The glass used in this 72 ED Evostar is different from the other glass used in other Evostar telescopes, however chromatic aberration is lower in small diameter refractors. 

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 72 ED telescope can be employed in astrophotography when used with its field flattener and reducer x 0.85. This accessory will reduce the focal ratio to f/4.93 and the focal length to only 357mm which is the perfect focal length for wide field objects such as the Andromeda Galaxy, Eta Carinae nebula or the center of the Milky Way.
