EvoStar 100mm f/9 Doublet APO Refractor (OTA only)
Product Description
A mounting cradle-ring clamps over OTA and allows the user to adjust the orientation and position of the scope relative to the mount to optimize viewing comfort and balance, while avoiding interference with other equipment. The scope is offered without a mount or tripod, but a Vixen-style dovetail plate makes it compatible with any alt-az or equatorial mount 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.
