Farpoint Parfocal Ring (individual) for 1.25" Eyepieces

The ring slips onto an 1.25" eyepiece barrel, allowing you to set the perfect focus point for that eyepiece. # Great for photographic purposes; matching an eyepiece's focus to your camera's focal plane will help you focus faster. # The ring allows you to make your set of eyepieces parfocal by adjusting the height of each eyepiece so that their focus points are the same, and you won't have to adjust focus when you switch magnifications in the field!
