PROFESSIONAL 10MM KELLNER 1-1/4" EYEPIECE
Kellner eyepieces were the most popular eyepieces for
moderately wide field telescopic systems prior to the
advent of some of the newer (and more expensive)
designs. 3 element coated optics with field of view
approximately 40 degrees and eye relief about 7mm.
Fits standard 1-1/4" focusers. Metal barrel with
knurled finger grip, and threaded for filters (thread is
courser than that used for standard eyepiece filters, but ID is slightly larg-
er. Put a little masking tape over the outside thread of your filter and it
will screw in nice and secure). 10mm focal length. Plastic container included.
Unused and a great value.
