Most eyepieces come from the factory with a cap for the "business end" of the barrel, and a plug for the insert barrel. If you buy a used eyepiece, however, it may not come with covers, or you might lose or damage your eyepiece caps and plugs and need a replacement. You should be able to find any size you need in this section, but before you buy, take a few minutes to do some measurements. If your eyepiece comes with a rubber eyeguard, can it fold down and accept a cap? If so, make sure you measure your eyepiece in that configuration. If the eyeguard will need to be removed for storage, then take that into consideration as well. Plugs are easier to measure for as a general rule. Just choose a 1.25" or 2" plug for the same size eyepiece barrel. If you need help choosing the proper cap, plug, or case, just give OPT a call, start a chat, or send an email. We're here to help!
