| This lightweight Astrozap light shroud fits the Meade 10” LightBridge truss-tube Dobsonian reflector only. It is made of durable black cloth, with double-stitched seams for durability. It improves image contrast, protects the mirror from dropped eyepieces, and retards the formation of dew. Quick-release drawstrings with push-to-open clasps at each end of the light shroud let you snug up the ends of the light shroud over the no-tools knobs. This holds the light shroud in place on the scope, making it easy to install on your assembled scope, and equally easy to remove when you’re done observing.
The six pole truss-tube design of the Meade LightBridge Dobs (compared to the eight-tube design of other Dobs) means that unless special measures are taken, an ordinary plain cloth light shroud will sag into your scope’s light path and effectively reduce your aperture asymmetrically. This Astrozap light shroud is not an ordinary plain cloth shroud.
It has two stiffening hoops (of the same flexible ABS plastic used in their roll-up dew shields) that help the light shroud keep its tubular shape. These 2” wide stiffening hoops are sewn into cloth pockets five inches below each end of the light shroud and effectively keep the light shroud cloth from sagging into the telescope light path. The stiffening hoops are designed to rest on the trusses just below the no-tool knobs that hold the trusses to the secondary cage and mirror box. Blocking the light path with a sagging light shroud becomes a non-issue with an Astrozap. |
