Cover For 16" & 18" Dobsonian Telescopes - TG4D

The TeleGizmos Cover for 16" and 18" Dobsonian Telescopes is a multi-layer polyethylene cover with a fully aluminized external surface, originally developed for NASA as spacecraft insulation. This durable cover features double-lapped sewn seams, a built-in drawstring for secure fastening, and excellent water resistance that helps prevent condensation buildup on telescopes stored outdoors. Its superior heat reflective properties significantly reduce scope temperature when left in sunlight, while the material remains malleable in sub-freezing temperatures and is resistant to tears, punctures, and UV damage—making it ideal for both temporary and extended outdoor storage of large Dobsonian reflectors.
