Explore Scientific 2" 100° Series Argon-Purged Waterproof Eyepiece - 9mm. Condition is Used.  Comes with end caps and original box.
For two years this has been my favorite eyepiece for viewing Abell Galaxy Clusters and Jupiter.  But I have upgraded to the ES 120° 9mm and no longer use the 100°.  I purchased this as a manufacturer refurbished eyepiece, thus it has no serial number.  Glass is perfect, only has a few set screw marks on the barrel.
I have included a sketch of Abell 1367 I made using this eyepiece, to demonstrate its capabilities with a 14" telescope under a Bortle 2 sky.
