The SVBONY SV152 20mm SWA Illuminated Eyepiece (1.25″) is designed specifically for guided star alignment, polar alignment, and astrophotography setup. Featuring a 70° apparent field of view and an adjustable illuminated reticle, it allows accurate centring of guide stars while maintaining a wide, comfortable visual field.

• Illuminated reticle eyepiece for accurate star centring and guiding
• 70° apparent field of view for wide, comfortable star acquisition
• 20mm focal length ideal for guiding and alignment tasks
• Adjustable LED brightness to suit night vision conditions
• Fully multi-coated optics for high light transmission and contrast
• Standard 1.25″ barrel compatible with most telescopes

Illuminated Reticle for Precise Guiding

The built-in LED illumination system provides a clearly visible reticle for precise centring of guide stars. Brightness can be adjusted to match observing conditions, ensuring the reticle is visible without overpowering faint stars. This makes the SV152 particularly useful for astrophotography alignment and guided tracking.

Super Wide Angle Field of View

With a 70° apparent field of view, the SV152 offers a significantly wider view than traditional illuminated eyepieces. This makes star acquisition easier and reduces the need for frequent repositioning when aligning mounts or guiding manually.

High-Quality Optics & Contrast

Fully multi-coated optical elements maximise light transmission while minimising internal reflections. This results in brighter star images, improved contrast, and better visibility of faint guide stars, even under challenging sky conditions.

Comfortable Eye Relief & Solid Construction

The SV152 provides comfortable eye positioning for extended alignment sessions. Its CNC-machined aluminium housing offers durability while remaining lightweight, making it suitable for both portable and permanent telescope setups.

Threading & Compatibility

The eyepiece features a standard 1.25″ barrel with filter threading, allowing compatibility with common astronomical accessories. It is suitable for use with refractors, Schmidt-Cassegrains, Maksutovs, and Dobsonians when precise alignment is required.
