To the category: Eyepieces for telescopes / Barlow Lenses
SIGETA 2x Barlow Lens — a professional optical accessory that significantly enhances your telescope's capabilities by doubling its focal length. At its core is a precision achromatic two-lens system that effectively minimizes chromatic aberrations. The precision metal housing with black anodized coating ensures reliable performance, while the unique brass compression ring provides secure protection for eyepieces. The special matte internal coating successfully prevents unwanted reflections.
The Barlow lens substantially expands your optical arsenal: a 25mm focal length eyepiece transforms into a 12.5mm equivalent while maintaining comfortable eye relief. This accessory proves particularly valuable for achromatic refractor owners, notably improving the quality of planetary observations and astrophotography results.
Modern fully multi-coated optics achieves an exceptional 97% light transmission, ensuring bright and high-contrast images. Pairing the Barlow lens with longer focal length eyepieces not only provides double magnification but also optimizes spherical aberration correction, creating ideal conditions for extended observations thanks to comfortable eye relief.
The standard 1.25" barrel diameter ensures universal compatibility with most modern telescopes and eyepieces. The built-in T-thread (M42x0.75) extends functionality by allowing DSLR camera attachment for planetary and terrestrial photography. The durable metal housing is complemented by protective caps for secure optics storage.
