USED Sky-Watcher Light Shroud for 10\" Truss Dob

Black is the best attenuator of visible light, and when the surface is not smooth, it greatly reduces low-incidence reflection. For the best performance from any truss Dobsonian, a shroud is a must. This one, custom designed for the 10" Collapsible Dob, is made of a stretchy nylon blend material that fits like a glove over the truss poles of the Dob, fastening with thick elastic bands on both ends. The water-resistant, opaque black fabric blocks stray light from entering the optical path, and the somewhat rough texture reduces the ability reflect light; this improves image contrast. It's also breathable, which minimizes unwanted vibration of the scope in breezy conditions. Use of the shroud will lessen the accumulation of dust and dirt on the mirrors during use, and will help prevent dew from forming on them.
