Lens edges blackened and internal matte threads effectively suppress stray light and glare, improving image contrast and making faint celestial objects easier to identify.
This 154mm lens adopts dual separation achromatic structure, serving as objective accessory for DIY refractive astronomical telescopes.
The achromatic optical design reduces light dispersion and optimizes astronomical imaging performance.
Made of professional optical glass, it features stable optical path transmission for telescope modification.
Dual separation lens structure realizes regular light convergence for various astronomical DIY assembly projects.
Its size matches corresponding inner diameter tubes, suitable for accessory replacement and homemade telescope construction.
Multi-group multi-element optical glass construction with broadband anti-reflection coating on surfaces, effectively increasing light transmission and reducing reflection loss, delivering bright and sharp imaging.
