Dobsonian Shroud for 20" Truss Tube DOB Telescope

This light shroud wraps around a 20" Truss Tube Dobsonian's open truss structure to block stray light from reaching the path between the primary and secondary mirrors. Keeping that path dark boosts image contrast and brings out more detail, which matters most for suburban observers dealing with nearby streetlights or porch lights. It's made from opaque black nylon that still breathes, so dust stays out while air can circulate around the optics, and elastic bands at each end keep it in place without extra hardware.

• Blocks stray light: opaque black nylon shroud keeps the primary-to-secondary mirror path dark for better contrast.
• Breathable material: lets air circulate to avoid pressure buildup from wind while still keeping dust out.
• Elastic-band fit: bands at each end hold the shroud in place for easy installation and removal.
• Drawstring closure: for a secure fit around the truss structure.
