About this product
Model: masuyama_2inch_ep_26mm
Part Number: MOP-26
Premium Masuyama eyepieces.
Dr Masuyama designs these Japanese-made five-element modified Plossl eyepieces.
Their traditional design benefits hugely from modern manufacturing techniques and premium, fully multi-coated optical glass.
When used in telescopes with f-ratio f/8 or above, their performance is very impressive!
The removable rubber grips also make them suitable for use in binoviewers.
The 2" versions with focal lengths 26mm or longer have long eye-relief, so they are comfortable for use with eye-glasses.
NOTE: All focal lengths have 85º FOV except the 45, 50 & 60mm.
