You know the little opaque caps that fit on the bottom of the eyepieces. I swear they are being stolen by raccoons while viewing the heavens. I loose one (At the least) every single trip out. I bought a had case with foam lining for my eyepieces, so I'm not so sure I really need them. How important are they if I keep my eyepieces well protected in a case? Each EP having it's own little foam compartment. ???
