Lanthanum Advantage

"Half the price of other Long-eye relief models, the Vixen Lanthanum eyepieces are ideal on small scopes that can't handle hefty wide-field eyepieces, providing good eye relief and a tall eyepiece for comfortable viewing."

"Among the best values in quality wide-angle eyepieces are the Vixen Lanthanum Superwides, made by Vixen of Japan. Each features 20mm of eye relief - an added bonus. Edge performance is very good …."

—The Backyard Astronomers Guide Revised Edition, pg. 73
