William Optics SWAN 25mm Eyepiece 2" (Pre-owned) 1.5X Barlow Ideal for securing cables andThe Swan eyepieces are super wide angle designs with a 72 apparent field of view. They use simple but sophisticated five lens optical systems for generally higher contrast than the more complicated optical designs used in some other super wide angle eyepieces that use up to eight lenses. All lenses are fully multicoated for high light transmission. Lens edges and internal field stops are blackened to reduce internal reflections and improve contrast.
