I have two Takahashi LE24 eyepieces, one is brand new that arrived from AEC today, the other is a year old but in essentially the same as new condition..........
I want to use them as a binoviewer pair....The new one is 1.0mm shorter than the old one and this may or may not affect binoviewing.
How do you tell which you have
The early ones have green writing, the current ones have white writing.
EDIT: Just measured them properly, the difference is in the nosepiece only so should be fine
