Sporting the large light bucket users have come to expect from a Dob, the Explore Scientific 10" f/5 Truss Tube Dobsonian Telescope gives users performance at a reasonable price. Its large parabolic primary mirror is highly reflective and corrects spherical aberration to eliminate distortion across the entire field of view, especially at the edges, with a 24% secondary mirror obstruction.

The large 10" aperture draws in copious amounts of light show awe-inspiring details on the Moon and planets, deep sky objects will be visible even for inexperienced observers, and bright star clusters are resolved 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 under 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 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.
