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!
