Thanks for the tip, Bob. I've not actually taken them off. But when turned to the left and full extension they then just keep rotating rather than actually coming off, or unscrewing and if I do try to tighten them after they are on full retraction they just keep rotating to the right.

Your posts about the eyecups on these may be a common issue, as
Zeiss issued another option on the new Conquest to offer the best
choice in eye relief options. They provided the other ones upon
request. I have the Conquest, and have both sets of eyecups.
I don't use glasses so either one works well for me.
The Conquest has 2 intermediate stops between full up and down.
They are made of plastic, and they do not offer the confidence of
the metal types found on other models.
The plastic ones do not seem to be as strong, and you need to retract
the eyecups with the Zeiss models just to squeeze them into the
case, that I have found they designed that way. That may be an issue
if you use the case much.
I owned the FL for a while, but I do not recall the eyecups and
construction, as I found them well done.
I am wondering about the HT and the new SF, are the eyecup barrels
plastic or metal ?
The advice offered above is sound, make sure they are on tight, and work
with the detents, there should be 2 int. stops.
