Astrozap Light Shroud For 12" Astro-Tech At12Rct Truss-Tube Ritchey-Chrétien

AstroZap LSAT12 Light Shroud for Astro-Tech AT12RCT 12" Truss Tube Ritchey-Chrétien

A truss-tube telescope like the Astro-Tech AT12RCT offers excellent rigidity with minimal weight—but that open design comes at a cost: stray light and airborne moisture can enter the optical path, reducing contrast and increasing the risk of dew. The AstroZap LSAT12 light shroud is a custom-fit solution designed to eliminate those problems with one lightweight, durable wrap.

Tailored specifically for the AT12RCT 12" truss-tube Ritchey-Chrétien, the LSAT12 is made in the USA from a black nylon/cotton blend fabric that’s double-stitched for durability. The fabric is breathable, flexible, and shaped to fit snugly around your scope’s truss structure. It maintains tension to prevent sagging into the light path and includes top and bottom drawstrings for a secure, movement-free fit—even in humid or breezy conditions.

By blocking stray light, the shroud helps improve image contrast, especially when observing or imaging from suburban locations. It also acts as a passive dew control system, insulating the central tube and helping your optics stay dry longer—without requiring power or a dew controller.

The LSAT12 pairs perfectly with the AstroZap DCAT12 dust cover (sold separately), giving you a full passive protection system to safeguard your scope in the field and in storage.
