Importance of the eyepiece The eyepiece is one of the most important components of a telescope. A single eyepiece can completely change the way a telescope looks. Even if the purpose of observation, gazing, or use is different, you can bring out the full potential of the telescope. You can also continue to use it even if you upgrade your telescope. Recommendation for wide-angle eyepieces When eyepieces have approximately the same focal length, the eyepiece with a wider apparent field of view will have a wider actual field of view. An eyepiece with a wider apparent field of view allows you to experience a more wonderful "space walk"
