Astrozap Dust Cover For Tube End Of Astro-Tech AT10RCT Truss-Tube Ritchey-Chrétien

AstroZap Dust Cover – For Tube End of Astro-Tech AT10RCT 10" Truss-Tube Ritchey-Chrétien

Simple, Secure Protection for Your Rear Cell and Primary Mirror

The AstroZap Dust Cover for the Astro-Tech AT10RCT 10" Ritchey-Chrétien is a lightweight, stretch-fit rear cover designed to protect the primary mirror and rear cell of your truss-tube telescope when not in use. Whether you're between imaging sessions or packing up after a long night, this cover keeps unwanted dust, debris, and moisture from settling where it doesn’t belong.

Crafted from durable black nylon, the cover features an elastic hem that fits snugly over the back of the optical tube. It’s shaped to accommodate the structural elements of the AT10RCT’s rear cell without interfering with fans or collimation screws. The breathable fabric won’t trap heat, and it folds flat or rolls easily for storage.

If you’re transporting your telescope or just keeping it protected between uses, this cover is an essential layer of defense for your optics.

Key Features:

• Custom Fit for AT10RCT Rear Cell: Covers the back of the 10" Astro-Tech Ritchey-Chrétien truss tube

• Dust and Debris Protection: Shields your primary mirror and electronics from particles and moisture

• Elastic Hem: Stretch-fit design stays secure without fasteners or straps

Compatibility:

Fits the rear tube end of the Astro-Tech AT10RCT 10" truss-tube Ritchey-Chrétien telescope. For front-end protection, pair with the matching AstroZap light shroud.

Storage Tip:

Cover your rear cell as soon as your session ends—even if your telescope remains outside. This helps maintain mirror cleanliness, minimizes cooldown turbulence from rear airflow, and shortens prep time before your next night under the stars.
