Astrozap Light Shroud for 12" Sky-Watcher Collapsible Truss-Tube Dobsonian

AstroZap Light Shroud for 12" Sky-Watcher Collapsible Dobsonian

If you own a collapsible truss-tube Dob like the Sky-Watcher 12" FlexTube, you already know the benefits of portability—but you’ve also likely encountered the downside: stray light sneaking in from every direction and bouncing off those exposed tubes. The AstroZap Light Shroud solves that problem beautifully, giving your open OTA the light-sealing performance of a solid tube without sacrificing the compact form factor.

This shroud is custom-made for the 12" Sky-Watcher Collapsible Dobsonian, fitting snugly over the truss section to block ambient light and improve image contrast—especially under suburban skies or when observing near artificial light sources. The fabric is a breathable, stretchy nylon blend that's both lightweight and durable, with double-stitched seams for long-term reliability. It slides on easily and secures in place with elastic-hemmed openings for a tidy, tailored fit.

Even better, this material won’t trap heat or encourage dew formation. It allows air to circulate freely so your optics can cool evenly, and it resists sagging—keeping it clear of your optical path, even when the telescope is tilted.

Features:

• Designed specifically for the 12" Sky-Watcher FlexTube Dobsonian

• Blocks ambient light and improves visual contrast

• Breathable, moisture-resistant fabric allows airflow to prevent dew

• Elastic ends keep the shroud securely in place on both ends

• Stretch-fit material conforms neatly to the truss assembly without drooping

• Double-stitched for long-lasting durability in the field

Observing Tip:

A quality light shroud can make the difference between seeing a faint galaxy and wondering if it’s there at all. If you observe near porch lights, street lamps, or even a bright Moon, a shroud like this helps preserve your dark adaptation and enhances contrast by keeping stray light out of the optical path.
