This Refracting Telescope ED Doublet has a 150 mm (5.9-inch) Aperture with two matched elements, one which is an Extra-low Dispersion (ED) element. It has a 1200 mm Focal Length with an f/8 Focal Ratio.
This refractor sports a Dual-speed 3.4-inch Rack-and-Pinion Focuser and has tube-ring attachment hardware with a D-style dovetail plate.
These doublet refractors deliver dramatic, coal-black skies and faithful, contrast-rich views of planetary and deep-space phenomenon that are second to none.
Sky-Watcher Evostar refractors are the logical choice for the discriminating amateur astronomer looking for an investment in advanced instrumentation for exceptional viewing and astrophotography.
