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.
