With a fast 550mm focal length and f/5.5 focal ratio, the Esprit 100EDX is ideal for wide-field astrophotography of nebulae, galaxies, star clusters, and large celestial targets.
The robust 3.4-inch linear rail rack-and-pinion focuser with 11:1 dual-speed micro focus provides smooth, precise focusing with excellent stability for imaging setups.
A built-in Camera Angle Adjuster and rotatable focuser make framing your target quick and convenient without needing to reposition the entire telescope.
The glossy white aluminum optical tube offers a premium look while keeping the telescope strong, durable, and ready for regular use in the field or observatory.
Includes essential astrophotography accessories such as tube rings, a D-style dovetail, M48 camera adapter, sturdy carry handle, and padded hard case.
