Eyepieces with an apparent field of view of 100° or more.
The term XWA stands for extreme wide angle. This includes all eyepieces with a very large apparent field of view of 100° or more.
Eyepieces with a very large apparent field of view and high edge sharpness are ideally suited for Dobsonian telescopes, as the large field of view makes manual tracking much easier. Object remain visible in the field of view for longer.
