Tele Vue 3.5mm Delos Local Only StarSense calculates the coordinates ofDescription Introducing Delos Tele Vue is pleased to introduce the Delos, mid to short focal length line of 20mm eye relief, 72 apparent field of view eyepieces. Every optical, mechanical, and ergonomic aspect was rethought to achieve reference standard performance for any visual application. The Delos was conceived as a narrower field Ethos. Reducing the field to 72 allowed freedom to increase eye relief, while controlling pupil aberrations, all
