SKYWATCHER EVOSTAR 100 ED is backordered and will ship as soon as it is back in stock.
The Skywatcher Evostar 100ED is an apochromatic doublet refractor that offers high performance for visual observers and astrophotographers. The objective lens features an extra-low dispersion glass (ED) element that minimizes the chromatic aberration for the best colour correction. As a result, planets and the moon are sharp at high magnification and for astrophotography the images have a high contrast.
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.
