The Antares FRE50 features correct image right angle viewing with a helical focus wire-x cross-hair giving 8.5 degrees of true field at 7X magnification, a significantly wider field than that of most of it's rivals. Rough focus is achieved by sliding the eyepiece in the diagonal. White in body color, it can be mounted to your telescope's accessory shoe with an F50FB or with F50DTB.
