This 5 element rich-field eyepiece in Erfle design offers good wide field of view and a comfortable viewing position. Its quality coatings prevent reflexions and lead to a bright image.
It is recommended for slow focal ratio or long focal length, such as Maksutov and Schmidt cassegrain telescopes.
With its apparent field of view of 52°, even large dimension of nebula or star cluster would become visisble. Please be reminded that the barrel of this SuperView 50mm is 2-inch.
