- ED Glass structure: The doublet air-spaced achromatic design with S-FPL51 ED glass reduces chromatic aberration, delivering crisp, accurate color images;
- Large aperture for bright images: The 102mm objective lens with an f/7 focal ratio brings more lights into the scope body and you will get more bright and clear image;
- FMC-coating for crisp image: Ultra-wideband multi-layer coatings and a retractable lens hood provide bright, wide-field images with sharp resolution, perfect for various types of observation;
- Dual-speed rack focuser: The 90mm back focus and dual-speed rack and pinion focuser with focus knob cover make it easy to achieve fine, accurate focus for both visual and photography.
