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.
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.
