I'm looking for a Hyperion rubber eye cup. They all use the same size.
It's this one:

I believe the Hyperions may actually come with two rubber guards. The other is essentially flat and just covers the M43 thread at the top of the eyepiece. I need the taller one to block out stray light.
Please PM me if you have a spare one. Thanks.
