Tele Vue Ethos 10mm 2/1,25 palca okulár

Wide-field eyepieces often force a compromise between immersive views and comfortable eye relief, but the Tele Vue Ethos 10mm eliminates that trade-off. It delivers a 100° apparent field with 15 mm of eye relief, allowing you to take in vast star fields without straining your eye.

Who is it for
