The Classic Dobsonian Telescope is considered a great entry-level telescope as it is about the best all-rounder at an affordable price. It provides way more light gathering power and resolution than a similarly priced refractor telescope. With its comparatively long focal length, the Orion 8945 SkyQuest XT8 telescope performs great viewing the moon and planets as well as deep space objects such as galaxies and nebulae.

High optical performance is provided by the telescopes parabolic main mirror with its Enhanced-reflectivity coatings boosting the reflectivity of the mirror to 94%. The high reflectivity, focusing as much light as possible to the eyepiece as well as the high Resolving power produces crisp and bright images for viewing.
A magnification of 48x is provided by the one included 25mm Sirius Plossl eyepiece. High-quality lenses guaranty for sharp images high in contrast. Additional eyepieces with varying focal lengths can be ordered and are a valuable addition.
Pointing the telescope to objects of interest is easy with the help of the Orion EZ Finderscope which is attached to the main tube. When it is adjusted and aligned to the telescope a small red dot in its center helps to find objects quickly.
Thanks to the stable Dobsonian mount and quality bearings, the telescope moves and pivots smoothly horizontally, as well as vertically without jerks and wobbles.
