## Long description

The Tele Vue DeLite 4mm 1.25" eyepiece is a short-focal-length astronomical eyepiece engineered for high-contrast optical performance in 1.25-inch focusers. With a 4 mm focal length it provides high magnification suited to detailed lunar, planetary and double-star observation. The design emphasizes compactness and low weight, making the eyepiece convenient to carry and quick to interchange during observing sessions.
Advantages
The eyepiece delivers strong contrast and sharpness across the field, enabling precise detail resolution at high magnifications. Its short focal length is optimized for fine planetary features and split of close double stars. The compact mechanical construction reduces weight at the telescope focal point and improves balance when using small to medium-sized telescopes. The 1.25" barrel ensures compatibility with a wide range of focusers and standard adapters.
Suitable for
Lunar surface observation and studying crater detail
High-magnification planetary viewing (e.g., Jupiter, Saturn, Mars)
Resolving and measuring close double stars
Visual observing sessions with small to medium refractors and reflectors
Key specifications
Focal length: 4 mm
Barrel diameter: 1.25 inches
Optical performance: high-contrast design for sharp planetary and lunar detail
Form factor: compact and lightweight eyepiece body
Recommended use: high magnification visual observation
How to use
Insert the 1.25" barrel securely into the focuser and tighten the focuser thumbscrew to hold the eyepiece in place. Begin with a lower-magnification eyepiece to locate and center the target, then switch to the DeLite 4mm to increase magnification. Allow the telescope to reach thermal equilibrium for stable images, and refocus carefully when moving between targets or when changing observing conditions. Use precise focuser adjustments and a steady mount to minimise image vibration at high magnifications.
Usage recommendations
For best results, use the eyepiece with telescopes that have adequate focal length and stable mounts to support high magnification. Start observing targets during moments of good atmospheric seeing, and consider using a high-quality Barlow only if additional eye relief or magnification adjustment is required. Store the eyepiece in a padded case and keep the optics covered when not in use to preserve contrast and coating performance.
