Eyepiece Tele Vue Panoptic 35mm 2" 82° apparent field of view

The Tele Vue Panoptic 35mm eyepiece is a 2" barrel optical accessory offering an 82° apparent field of view. Engineered for wide-field visual observing, this eyepiece provides a large, comfortable image circle with low edge distortion and high contrast. It delivers low to medium magnification suitable for scanning star fields, observing extended deep-sky objects, and locating targets quickly through star-hopping. The design fits telescopes equipped with 2" focusers and is optimized for visual astronomy sessions where a broad, immersive view is required.

Advantages

The eyepiece combines a very wide apparent field with a long focal length to produce expansive views while maintaining sharpness toward the field edge. Its optical construction reduces aberrations and allows for comfortable eye placement and good eye relief, which supports prolonged visual use. The 2" barrel ensures compatibility with standard 2" focusers and accessories, making it versatile across many telescope types.

Suitable for

• Wide-field visual observing of star fields and open clusters
• Deep-sky viewing of large nebulae and galaxies at low to medium magnification
• Star-hopping and target acquisition during observing sessions
• General-purpose eyepiece use on telescopes with 2" focusers

Key specifications

• Barrel diameter: 2 inches
• Focal length: 35 mm
• Apparent field of view: 82°
• Designed for visual observing at low to medium magnifications
• Optimized for minimal edge distortion and good contrast

How to use

Insert the 2" eyepiece into the telescope focuser and secure it according to the focuser's locking mechanism. Start with a stable mount or tripod and set the telescope to a low-power setting to take advantage of the wide field. Adjust focus slowly to achieve a sharp image; use the telescope’s slow-motion controls if available for fine framing. To locate specific objects, use wider star fields for context and then increase magnification with additional eyepieces if needed.

Usage recommendations

Use with a well-collimated telescope and an appropriate focal ratio to maximize edge sharpness. For best comfort during extended sessions, pair the eyepiece with an adjustable or threaded eyecup and ensure proper eye relief for eyeglass wearers. When imaging is attempted, expect this eyepiece to be optimized for visual use rather than astrophotography.
