Effectively cover your Newtonian or SCT telescopes both at star parties and in storage. This white, 420 denier, polyurethane coated nylon fabric will reflect the sun, resists dust and moisture and is long-lasting. Our covers allow positioning in the horizontal when not being used so that high winds won't knock them over. It has a draw pull to fit snugly around the bottom. A sturdy P nylon strap is provided to attach a weight to the top end, keeping the wind from standing the scope up or turning it into a cosmic weathervane. The water and dust resistant polyurethane inner coating plus a silicone outer spray complete protection package for extended observing sessions in the bush. The Newtonian cover comes with a storage bag and secondary mirror cover, both with draw pulls. Worth every penny in strength, longevity and protection. The AstroSystems telescope cover is not intended for continuous outdoor exposure.
