Triplet lens design for anastigmatic flat field suitable to complement the high image quality of the Hyperion Zoom. Converts every Hyperion Zoom into a 3.5 - 10.5mm high power Astro-Zoom eyepiece.
Together with the T-2 adapter(included) the Hyperion-Zoom Barlow can likewise serve for any other projection application from 1.3 up to 6x magnification factor. The image quality truly is astonishing. We found no difference to the original Carl Zeiss Jena barlow units.
