Orion SkyQuest XT10g - Computerized GoTo Dobsonian

Orionskyquestxt10g

Keywords: Advanced Dobsonian Reflector

Description

Due back in 12 days on April 30, 2019 (Tuesday).

The SkyQuest XT10g features GoTo pointing convenience. It features a 254mm (10") aperture, 1200mm focal-length parabolic mirror (f/4.7) made from low-thermal-expansion optical glass. Enhanced reflectivity (94%) aluminum mirror coatings yield bright, high-definition images. The 10" primary mirror is center-marked to make precise alignment of the optics (collimation) easier to achieve. The reflector telescope's open mirror cell design facilitates efficient cooling of the mirror to ambient temperature.

The XT10g telescope optical tube drops into the Dobsonian base on a dovetail trunnion and locks in place with a single hand knob. A simple two-star alignment is all it takes to orient the telescope to the sky for GoTo operation. Then let the fun begin! When you're ready to call it a night, just loosen the knob and lift the tube off the base for easy transport or storage. Handles on the Dobsonian base's front and side panels make it easy to lift and carry, whether you're going from car to field, or from house to backyard.

The Orion SkyQuest XT10g GoTo Dobsonian also includes an EZ Finder II reflex sight, eyepiece rack for one 2" and three 1.25" eyepieces, hand controller bracket, and a quick collimation cap.
