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

AstroZap Light Shroud – For 12" Astro-Tech AT12RCT Truss-Tube Ritchey-Chrétien

Block the Glare. Seal the Tube. Sharpen the View.

The AstroZap Light Shroud for the Astro-Tech AT12RCT 12" Ritchey-Chrétien helps your telescope perform at its best by blocking stray light, stabilizing airflow through the truss structure, and protecting internal components from dust, dew, and glare.

This lightweight, breathable black nylon shroud stretches snugly between the front and rear cells of the open truss-tube assembly, forming an opaque barrier that shields the optical path from unwanted ambient light—whether from a distant porch light or the glow of a nearby laptop. The moisture-resistant fabric won’t trap heat and won’t sag into the light path, even during extended sessions.

Whether you’re imaging under dark skies or observing from the backyard, this simple upgrade can make a meaningful difference in both contrast and mirror cleanliness.

Key Features:

• Custom Fit for Astro-Tech AT12RCT: Designed specifically for the 12" truss-tube RC

• Blocks Ambient Light: Improves contrast by eliminating side glare and internal reflections

• Breathable Black Nylon Fabric: Lightweight, moisture-resistant, and thermally stable

• Stretch Fit Design: Secure and sag-free, even during extended use

• Protects Internal Components: Keeps dust, insects, and airborne debris out of the truss

• Made in the USA: Built by AstroZap for real-world observing conditions

Compatibility:

Fits the Astro-Tech AT12RCT 12" truss-tube Ritchey-Chrétien telescope. Not compatible with solid-tube telescopes or non-Astro-Tech truss designs.

Observing Tip:

Installing a shroud doesn't just help block light—it can also reduce thermal turbulence inside the tube by limiting unpredictable air movement through the truss. The result? A steadier image and better high-power performance, especially on nights with light wind or uneven cooling.
