Triple Model Options for Diverse DIY Needs Available in three specifications—D73F330, D73F280, and D73F276—the 73mm objective lens set caters to different telescope focal length requirements, supporting the assembly of compact astronomical scopes, collimators, and customized observation devices for hobbyists.
Achromatic Refractive Cemented Structure for Clear ImagingAdopts a professional refractive cemented design that combines multiple optical elements, effectively eliminating chromatic aberration and color fringing around celestial targets, and presenting sharp, true-color views of the moon, planets, and bright star clusters.
Dual Coating Choices (Green/Red Film) for Enhanced Light Performance Offers both green and red anti-reflective coating options, both of which boost light transmittance, minimize glare and stray light interference, and improve image contrast for clearer observation even in low-light nighttime environments.
Standard Dimensional Design for Universal Compatibility With standard 73mm caliber parameters, the objective lens fits most DIY telescope tube assemblies and collimator mounting brackets, serving as a reliable replacement or upgrade part for astronomy enthusiasts' homemade optical projects.
High-Density Optical Glass Construction for Longevity Crafted from premium optical glass, the lens maintains stable optical performance under varying outdoor temperature conditions, resisting scratches and minor impacts to support long-term stargazing and collimator calibration use.
