You're supposed to put this stuff in a drawer and leave it there. Every five years you look in the drawer and say "wotthehell is this stuff?" and then close the drawer again. Problem solved.
There is another solution. I just used it. Astro life is full of gizmos. so for example I just got the Baader visual back for my Vixen SD81s, thereby displacing the OEM visual back.
So, I put the OEM visual back in a baggie. And I wrote a note. The says, "OEM visual back Vixen SD81s." Then I close up the baggie and put it away. That way when I find it in five years I know what it is.
After five years you'll just be used to having it around and won't bother trying to sell it for twenty bucks. You'll know what it is, and it will go back in the drawer anyhow. When you die, puzzled relatives will chuck it even though they are likely to resell the actual scopes.
This is why year after year people buy these gizmos. Shout-out to the person who turned me on to the availability of this part (by posting about it recently). I'm afraid I've forgotten his name.
