Meade LightBridge overview

  • 1Description

Sporting the large light-bucket that is the hallmark of a Dobsonian, the Meade Instruments LightBridge 254mm f/5 Truss-Tube Dobsonian AZ Telescope gives users performance at a reasonable price. Its large primary parabolic mirror draws in copious amounts of light to reveal awe-inspiring details on the Moon and planets, and deep sky objects will be visible even for inexperienced observers.

Its impressively-fast f/5 focal ratio and 10:1 dual-speed Crayford focuser makes this an ideal choice for imaging deep sky objects. The fast focal ratio enables devices to capture images in less time than slower scopes with a significant reduction in the noise that can decrease resolution on imaging sensors. The focusing mechanism employed in the Crayford design gives it the ability to achieve tack-sharp focusing with zero backlash; and with a focus lock and tension adjustment, the focuser performs with the high precision required for viewing and imaging deep space objects. 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 floor mount weighs-in at 27-pounds and provides a rock-steady observational platform with very low vibration. This rocker mount features Teflon-coated roller azimuth bearings and large-diameter aluminum altitude bearings that allow the optical tube to move smoothly with limited vibrations. 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.
