William Optics & Stellarvue bino's have the same body, made by the same manufacturer (I think) with nearly identical specs (other than the eyepieces & colours). They both cost around the same too, the Stellarvue are probably slightly cheaper but they only come with 2x 20mm 50deg ep's compared to 2x 20mm 66deg ep's with WO's (the supplied 66deg WO ep's perform pretty poorly by the way, the star images near the edges even look worse than the old basic no-brand ep's I came across).The TV bino's have a big aperture, around 26mm if I remember correctly, allowing you to use larger/longer ep's without significant vignetting that will become obvious on the WO/Stellarvue as soon as you start using ep's 25mm and above.
