Sky-Watcher

Apochromatic doublet


 

The Skywatcher Evostar 80ED Imaging Kit includes the popular Evostar 80ED apochromatic doublet refractor, dedicated field flattener/reducer, plus upgraded finderscope with Testar helical focuser, which allows you to use it as a guidescope with 1.25" barrel-sized guide cameras such as the ASI120MM Mini

The Evostar 80ED is an apochromatic doublet refractor that offers high performance for visual observers and astrophotographers. The objective lens features an element similar in performance to FPL-53, 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 0.85x field flattener/reducer turns the scope into a powerful astrograph corrected for the APS-C format.

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 Evostar telescopes and its small dimension and affordable price makes this telescope the best entry level apochromatic refractor for astrophotographers.
