WEll, not quite. I'm sorry if it wasn't clear. Close, but not exact.
I was slightly mistaken in how to measure the eyepieces with a skirt. The Ethos 13, if used as a 2", requires setting 1 (all the way out). That is close to the optimum setting. If used in the 1.25" mode, setting 5.
The Ethos 8mm, if used as a 1.25" eyepiece with the standard Paracorr adapter, requires setting 4. It is not usable in a 2" mode unless a barrel extension is added to the eyepiece, in which case the eyepiece would be pulled out 12.4mm from the Paracorr, with the PC in setting 1. In other words, this eyepiece requires the use of the 1.25" adapter in setting 4. I wouldn't bother to try to use it as a 2" eyepiece in the Paracorr. Just remember that this requires some in-focus movement of the focuser.
