SVBONY 1.25" Illuminated Crosshair Eyepiece – 12.5mm
The SVBONY 12.5mm illuminated reticle eyepiece is an essential tool for accurate polar alignment, GoTo mount star alignment, and telescope finder calibration. Featuring a precision etched cross-line reticle with adjustable LED illumination, it allows exact centering of alignment stars for improved tracking and pointing accuracy.
Built around a high-quality Plössl optical design, this 1.25" eyepiece delivers bright, sharp star images with a 40° apparent field of view, making it ideal for both visual alignment work and astrophotography setup routines.
Precision Polar Alignment & GoTo Setup
The illuminated crosshair reticle makes it easy to precisely centre Polaris, alignment stars, or guide stars, significantly improving mount accuracy, tracking performance, and GoTo precision. A superb upgrade for equatorial mounts, finder scopes, and star alignment routines.
Adjustable LED Illumination
The built-in LED reticle illuminator features adjustable brightness control, allowing you to fine-tune the crosshair intensity depending on sky darkness and target brightness. This helps maintain visibility without overwhelming faint stars.
Sharp Fully Multi-Coated Optics
Fully multi-coated optical surfaces maximise light transmission and contrast, helping stars remain sharp and easy to centre. The 12.5mm focal length provides an excellent balance between magnification and field size for alignment tasks.
Durable Metal Construction
Designed for repeated field use, the all-metal body provides excellent durability and a premium feel. The standard 1.25" barrel ensures compatibility with most telescopes, finder scopes, diagonals, and guiding accessories.
