William Optics SPL and SWAN Eyepieces

William Optics SPL and SWAN eyepieces cover two different jobs at the eyepiece. The SPL 55° 12.5mm is a 1.25" eyepiece with a moderate apparent field, useful for medium to high magnification on the Moon, planets and double stars.

The SWAN 72° 40mm is a 2" wide-field eyepiece with a long focal length, made for low-power views of large star clusters and nebulae. Together they make a simple two-eyepiece set for a refractor.
