I reckon there's quite a few of us who have done/are doing that! It's probably the same bunch of eyepieces doing the rounds too?. I swear I have bought an ep or two (the same actual eyepiece, that is - not just 'another one') that I had sold a few months earlier - TV plossls are a good one for that! Wouldn't it be interesting to be able to track them to see who and where they go to next?

I know for a fact Roy that I have bought back eyepieces previously sold, mostly to people I consider friends, and sometimes only a matter of several weeks !

Barcodes on the barrels ! Whatever next.
