TS-Optics 2" ERFLE 50mm Rich-Field Eyepiece - 52° Field

TS-Optics 50mm 2" ERFLE eyepiece


This 5 element rich-field eyepiece in Erfle design offers good field definition, a wide field of view and a comfortable viewing position. Its quality coatings prevent reflexions and lead to a bright image.



It is recommended for slower systems like RC, ACF, Schmidt-Cassegrain and EHD telescopes and Achromats from f/7 and longer.



With its apparent field of view of 52°, even larger nebulae become visible. A 150/1200 mm telescope with this eyepiece has a magnification of 24x and a true field of view of more than 2° - this is four times the diameter of the moon!
