The Baader Morpheus 17.5 mm eyepiece provides a true flat 76° apparent field with very low distortion and high contrast, keeping stars sharp to the edge. Its 23 mm eye relief supports relaxed viewing, including for eyeglass wearers. The integrated M43 thread enables photo/video eyepiece projection (classical or afocal). Dual 1.25″/2″ barrels with Safety-Kerfs and Phantom Coating® Group complete the optical-mechanical package.
