eviscerating eyepieces (warning)

Most modern eyepieces are designed so that if you remove the barrel to clean the lower lens element, everything stays put together. There are a few who will disgorge their innards into your hand.

One is the 22mm (old) Pan Optic.

Another, I discovered a few days ago, is the 28mm Edmund RKE. I'm not sure if the other RKEs are "disgorgers" but they might be.

If there are other eyepiece brands that disgorge their innards when you remove the barrel I'd like to know about it.

40 TV Plossl. Took 5 tries to get it back right.

The old Nagler 16mm Type 2 does. It also has a tendency to have the field stop unscrew from vibration. I always know I have the problem when I start getting an oval field of view! Once someone at Televue talked me thru "the fix" I can now do it in less than a minute. However I still have to be careful not to dump the lenses when doing it.
