I am an amateur astronomer and use the Lenscoat Hoodies as lens covers for my refractor telescopes. I recommend these 110% to all telescope users who need a top quality lens cap. They are excellent quality, robust, non-marring on the dew shield paint, easy to mount and have an extremely nice, reinforced well padded fronts to protect that valuable objective. AND they look fantastic on scopes. Thanks Lenscoat!
