This combination of glass lenses and coatings virtually eliminates chromatic aberrations for clear and bright high-contrast images with true color rendition.
This is a versatile optical tube assembly (OTA) that is well suited for wide-field astronomical observation of prominent nebulae star clusters and galaxies or can be used as an astrograph for sky photography a terrestrial spotting scope or telephoto lens. The larger 120mm aperture of this ProED model not only increases image brightness over the smaller 80mm and 100mm versions it improves resolution and contrast.A mounting cradle-ring clamps over OTA and allows the user to adjust the orientation and position of the scope relative to the Mnt to optimize viewing comfort and balance while avoiding interference with other equipment. The scope is offered without a Mnt or tripod but a Vixen-style dovetail plate makes it compatible with any alt-az or equatorial Mnt with a Vixen-style saddle.Its two-speed Crayford-style focuser helps make fine-focusing fast and precise without backlash.
The EvoStar comes with several accessories to help you get observing faster and easier. First are two long eye relief eyepieces that produce 30 and 120x magnification a 90? star diagonal for more comfortable viewing and a large 8x50 erect-image finderscope to make finding your celestial objects faster and easier. Finally Sky-Watcher provides a foam-lined aluminum carrying case to safely store and transport the OTA.
