It uses multiple internal baffles to prevent off-axis reflections for excellent contrast, and a retractable lens shade helps eliminate glare and dew buildup. With gloss-black machined construction, and attractive satin-red features and accessories, the Orion EON 104 mm ED-X2 telescope is a truly gorgeous astronomy instrument that you'll be sure to appreciate having bought!
This beautiful piece of optical engineering includes a hybrid-drive 2.7-inch Rack and Pinion focuser capable of supporting imaging trains of up to 17.6-pounds of weight. The focuser features 11:1 ratio dual speed controls that allow for a remarkable level of precision and fine tune focusing. You can rotate the focuser 360-degrees to optimize imaging or observing convenience. The focuser permits 60 mm of backfocus travel, and has a built-in focus lock knob. A step-down 1.25-inch adapter makes the EON 104 mm ED-X2 compatible with either 2-inch or 1.25-inch size accessories.
