The Celestron 12.5mm Ortho Eyepiece with Reticle (1.25") is a specialized eyepiece designed for those who need high magnification along with precise targeting and measuring capabilities. The addition of a reticle (a built-in crosshair or grid) makes this eyepiece particularly useful for applications such as astrophotography, guiding, and lunar or planetary observation where precise alignment or measurement is important. This eyepiece combines the sharpness of an orthoscopic design with the functionality of a reticle, offering an excellent balance for both casual observers and more advanced users.

Key Features:

• 12.5mm Focal Length: The 12.5mm focal length provides medium-to-high magnification, making it ideal for observing the finer details of planetary surfaces, lunar features, and other high-contrast objects in the night sky. It provides a balance between magnification and field of view.

• 1.25" Barrel Size: The eyepiece fits into a standard 1.25" eyepiece holder, making it compatible with most telescopes that accept 1.25" eyepieces. This ensures compatibility across a wide range of telescope setups.

• Orthoscopic Design: The 12.5mm Ortho eyepiece uses a classic 4-element optical design. Orthoscopic eyepieces are known for their sharp, high-contrast images and minimal distortion. This design produces clear, crisp images with excellent edge-to-edge sharpness, especially valuable for planetary and lunar observations.

• Reticle for Precision: The integrated reticle provides a fine crosshair or grid pattern in the field of view, useful for:

  • Astrophotography: Helps with accurate alignment and centering of objects in the camera's field of view.
  • Guiding: Assists in tracking and guiding during long exposure astrophotography by helping to align celestial objects precisely.
  • Planetary and Lunar Observing: Allows you to measure and track specific features or objects in the sky with great accuracy.

• Fully Coated Optics: The lenses feature multi-layer coatings that enhance light transmission, reduce reflections, and improve image contrast. This results in brighter and clearer images, especially in lower light conditions.

• Compact and Durable: The eyepiece has a robust metal housing, designed to withstand regular use while remaining compact and easy to handle. The durable construction ensures longevity and performance over time.

• Excellent for High-Contrast Objects: The combination of the orthoscopic design and reticle makes this eyepiece especially well-suited for high-contrast celestial objects like planets, the Moon, and bright stars. The high level of detail and contrast will reveal the fine surface features of planets and the intricate topography of the lunar surface.
