SVBONY SV503 Astronomical Telescope Refracting Telescope Aperture 102mm ED Glass Focal Length 714mm OTA Lens Barrel Only High Magnification Gakken

【ED Glass】The objective lens adopts 2-element ultra-low dispersion ED glass, provides clear and high contrast images for travel and mobile use. Provides optimal color correction to achieve clear and beautiful images. 【Dual Focus】SV503 102mm refractor telescope has constant speed and fine speed focusing knob. The 1:10 micro reduction is ideal for astrophotography, allowing you to quickly and accurately focus. The 2" RAP (rack and pinion) focuser allows you to safely place heavy photographic accessories. [FMC Coating] The entire optical lens uses an anti-reflection super multi-coating (FMC) process to increase light transmittance and suppress internal reflections that cause flare and ghosting. 【Compatibility Adapter】SV503 refractor telescope is compatible with all 1.25" and 2" accessories, including eyepiece diagonal Barlow lens for 2" to 1.25" adapter. [Suitable for beginners] SV503 102mm refracting telescope is suitable not only for experienced observers but also for beginners.
