A simple plastic cover designed to keep dust out of your 1.25″ or 2″ accessories. This includes all standard barlows, diagonals, focusers, eyepieces, etc. Perfect to replace the factory caps and plugs you may have misplaced since buying your telescope.
Use a dust cap to cover the front end of your eyepieces and barlows by “capping it on top of the lens”
Use a dust plug to cover the back end of your accessories by “plugging it inside the optical tube”
