Orion Light Shroud for SkyQuest XX12 Dobsonian Telescope
|Custom-designed light shroud for the XX12 Truss Tube Dobsonian telescope blocks stray light to improve image contrast |
Black shrouds are usually so funereal - but not when you're talking truss tube Dobs! For the best performance from any truss Dobsonian, a shroud is a must. This one, custom designed for the SkyQuest XX12, is made of a stretchy nylon blend material that fits like a glove over the truss poles of the XX12, fastening with thick elastic bands on both ends. The water-resistant, opaque black fabric blocks stray light from entering the optical path, thus improving 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. Made in the U.S.A.
WARNING! When using a truss tube Dobsonian telescope for solar observing, always use a Light Shroud and a properly sized solar filter. When you install the Light Shroud make certain there are no gaps between the Shroud and the telescope where direct sunlight can reach the telescope mirror. When a truss tube telescope (equipped with a solar filter but no Light Shroud) is pointing near (not at) the Sun, direct sunlight can hit the mirror and focus on the solar filter or other portions of the telescope. This can lead to eye injury or damage to the telescope. Using a Light Shroud protects your telescope from peripheral sunlight.
Before using any telescope for solar observing, make sure to install all dustcaps or other protective covers on all optical components such as finder scopes to keep sunlight from passing through them. Glancing through an uncovered optical system, even for an instant, can cause permanent eye damage. Always install protective caps on all optical instruments if left out during daylight hours.
