Product description Sporting the large light bucket users have come to expect from a Dob, the Explore Scientific 12" f/5 Truss Tube Dobsonian Telescope gives users awe-inspiring performance at a reasonable price. Its large parabolic primary mirror is highly reflective and is engineered to correct spherical aberration which eliminates distortion across the entire field of view, especially at the edges. The large 12" aperture draws in copious amounts of light to show the minutia on the Moon and planetary surfaces, reveal deep sky objects that smaller scopes simply cannot not see, and resolve bright star clusters to their core. Its f/5 focal ratio and 10:1 dual-speed helical focuser makes this an ideal choice for imaging. The fast focal ratio enables devices to capture images in less time than slower scopes, while the unique focusing mechanism employed in the helical design gives it the ability to achieve tack-sharp focusing with zero backlash that rack-and-pinion focusers are generally unable to. This 2" focuser will accept larger eyepieces so users can enjoy a truly immersive visual experience and will ensure larger imaging sensors are completely covered.The rocker box weighs-in at just over 15 pounds and provides a rock-steady observational platform with very low vibration. This rocker mount features high-altitude bearings with aluminum structures that allow for fine adjustment flows at high magnifications, and dual radial primary mirror fans to quickly adjust the temperature to reduce mirror distortion. Finally, the tension control handle allows users to adjust the settings allowing them to move the mount easily and smoothly by hand with minimal vibration and maintain its position when released. - Performance
