EYEPIECES
A wide range of eyepieces are available for use with MM2 Fieldscopes. Choosing the best eyepiece is often confusing but making the right choice will depend on price and application. It is important to remember that the eyepiece is an integral part of the whole setup and opting for a lower quality lens will make a difference to the overall image quality derived from the instrument.

MM2 • HR MM2 EYEPIECES
Dedicated eyepieces for the MM2 and the best choice as a first eyepiece. 40909 HR MM2 13-39x delivers a sharper image with a wider field of view.

HR EYEPIECES
Long eyerelief eyepieces delivering full field of view with spectacles. 40933M is the highest magnification option of the more expensive zoom eyepieces available. Eyepieces in table marked * have a twist-type eyecup.

HDF EYEPIECES
The preferred choice for quality and viewing comfort, HDF eyepieces have large dia. eyelenses and provide 'walk-in' field of vision. Eyepieces feature long eyerelief for full field of view with or without spectacles and fixed magnification models are wide angle. 40858M, 40859M and 40862M are the recommended eyepieces for the ED models. Eyepieces in table marked * have a twist-type eyecup.
