45mm Masuyama MOP-45mm 53°

Current retail is $395 + taxes and shipping so this is your chance for some savings. For my location a new one would cost $447.16 delivered via priority mail

Latest version ( like-new/ used 1 time ) of a rather rare eyepiece and long focal length, 60 mm; excellent for low power, richest-field views in long focal length.  I picked it up at the local astronomical shop a short train ride from Kyoto last December.  I decided I just have too many low powered pieces given my viewing cadence.

Apparent field of view : 53-degree

Eye relief : 32mm

Field stop : 40mm 

Lens configuration : 5 elements in 3 groups

$325 delivered via USPS priority mail which is included in the price.

Good notes from a previous educated sellers post…

( i.e, slow, > f/7 ) telescopes especially Schmidt-Cas, Maksutov, Dall-Kirkham and etc.  Optical elements are clean.  Wide rubber grip is removable. It screws off ( see photos ) and is replaced with included metal thread-protection ring.  Japanese-made five-element modified Plossl design by Dr Masuyama. The design benefits from premium, fully multi-coated optical glass.

Thanks for looking
