Agena offers what is arguably the largest selection of after-market end caps and dust plugs in the astronomy industry. Available in dozens of sizes and in a choice of materials and colors, we just might have that hard-to-find end cap to replace the one you lost (or never had) for your eyepieces, binoculars, accessories, etc.
Black plastic cap. Sold individually.
Please note that the inside of this end cap has an imprint of "51.5." This refers to the dimension (D) of the cap (see definitions below) and not dimension (A) which is the usable inner diameter of the end cap and is a bit smaller than the marked size.

It's pretty much the only choice.Pros:
Strong Construction,CompactCons: Comments:
This is pretty much the only choice for reticle eyepieces and for finder scopes. And it is only available here. I did purchase another brand a while back that had a flashing feature but it was big, bulky, and broke after first use.
It would be nice for these things to turn off automatically after a few hours of non use. I just can't seem to remember to turn them off and I'm always replacing batteries.
