Default Eye relief??????????

Do i want an eyepiece with a long eye relief or short eye relief, the kowa 25x eyepiece for the 660 series has a 31mm eye relief, is that good for digiscoping? I thout the eye relief was the distance between your eye and the eyepiece lens.

Hi Pauly,

Yes, eye relief refers to the distance between your eye and the eyepiece for a full circle image view. Think rifle scope for hunting, etc. Since the camera will be mounted in very close proximity to the eyepiece, eye relief is, of itself, not a major factor. What is more important is the diameter of the ocular on the eyepiece. Generally, the larger the exit pupil, the less vignetting you would likely get. You might want to post this question for Andy Bright. Andy used to use a Kowa for digiscoping, and would be most likely to be able to give you an accurate answer.
