AstroZap Dust Cover – For Tube End of Astro-Tech AT12RCT 12" Truss-Tube Ritchey-Chrétien

Keep the Rear Cell Clean, Covered, and Ready for Clear Skies

The AstroZap Dust Cover for the 12" Astro-Tech AT12RCT Ritchey-Chrétien is a lightweight, durable solution for protecting the rear cell and primary mirror of your truss-tube telescope between observing sessions. Whether your scope is permanently mounted or traveling to a dark site, this stretch-fit cover helps preserve optical performance by keeping out dust, insects, and airborne moisture.

Made from breathable, black nylon fabric, the cover slips snugly over the back end of the truss structure using a flexible elastic hem that holds it securely in place—no tools or fasteners required. The design is shaped to fit around structural elements without interfering with fans, collimation screws, or other rear cell features.

Rolls up easily for storage and offers essential protection whether your scope is resting in an observatory, garage, or travel case.
