Tele Vue DeLite 13mm 62° Eyepiece - 1.25"

20mm Eye Relief and Adjustable Locking Eyeguard

The Tele Vue DeLite 13mm is engineered with a constant 20mm eye relief and a sliding mechanical housing to ensure consistent, comfortable eye placement for all observers. This long-relief design allows eyeglass wearers to maintain enough clearance to see the entire 62° field without contact between spectacles and the eyepiece. By locking the eyeguard at the specific height required for your eye's anatomy, you effectively eliminate the blackouts and "kidney-beaning" caused by improper eye positioning.

• Sliding Locking Eyeguard: Provides a physical hard-stop to secure the optimal eye point for consistent viewing sessions.
• Dioptrx Compatibility: Integrates directly with Tele Vue Dioptrx lenses to resolve eyesight astigmatism while maintaining the ergonomic benefits of long eye relief.

13.8mm Field Stop and Framing Capacity

With a 13.8mm field stop, the Tele Vue DeLite 13mm is designed to provide a true field of view that frames compact deep-sky objects such as the Hercules Cluster (M13) with significant dark sky context. In an 8-inch f/6 Dobsonian, this eyepiece produces 92x magnification, a combination that balances background sky darkness with enough scale to resolve outer stellar members. The 62° field format is physically smaller than the Delos or Nagler lines, facilitating easier balance on lightweight mounts.

Operational Comparison

Observers often evaluate the Tele Vue DeLite 13mm against wider-field designs based on weight, eye relief, and specific telescope requirements.

• vs. 13mm Nagler Type 6: The Nagler provides an 82° field but limits eye relief to 12mm, whereas the DeLite 13mm provides 20mm of eye relief for eyeglass compatibility.
• vs. 12mm Delos: While the Delos offers a 72° field and 20mm eye relief, the DeLite 13mm weighs approximately 45% less, improving balance on lightweight tracking mounts.
