About this product

Model:  founder_alien_ep_3

Founder Alien eyepieces have a long 20 mm eye-relief design for comfortable high-magnification observing of lunar and planetary targets. 

They deliver bright, high-contrast views with very low chromatic aberration.

The nosepieces have a milled safety undercut and are threaded to accept 1.25" astronomy filters. 

The eyepieces also have soft rubber eyecups and are parfocal, so they require little or no refocusing when changing from one to another.
