2" Barrel Design
Designed with a 2” barrel, a standard size across the market of astronomy accessories available, effortlessly join a host of eyepieces, cameras, and other observing equipment to your telescope. A 2” size is also ideal for imaging with large sensors and wide field eyepieces thanks to its sizable aperture.
