2" Kokusai Kohki 30mm Wide Scan Type II - 88-degree AFOV
** MINT condition with original box and end caps **
Very slight set-screw marks on barrel. A separately purchased rubber eye guard will also be included.
The 30mm Widescan is the *perfect* wide-angle eyepiece for SCT's and other slow scopes, providing an incredible field of view - wider true field than the 40mm Pentax XL. A paracorr or other coma-corrector is recommended when used with a fast scope. This eyepiece yields a brighter image than the much heavier 31mm Nagler at a third the cost (although admittedly, the Nagler excels in edge sharpness).
* accepts standard 48mm filters
* 20mm eye relief
* multi-coated lens elements (5)
