SVBONY SV503 Astronomical Telescope Refracting Telescope Aperture 70mm ED Glass Focal Length 420mm OTA High Magnification Lens Barrel Only 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 70mm refractor telescope has constant speed and fine speed focusing knob. The 1:10 micro reduction is ideal for astrophotography and allows for precise focusing right away. 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 (SMC) process to increase light transmittance and suppress internal reflections that cause flare and ghosting. 【Retractable & Compatible Adapter】SV503 refractor telescope weighs only about 2.22kg and has a length of only 301mm /11.85inch with the retractable outcrop cover. Also compatible with all 1.25" and 2" accessories, including eyepiece diagonal barrow lenses for 2" to 1.25" adapters.

SV503 70mm ED Lens Telescope is suitable for astrophotographers, visual observers, nature observers, starry sky and nature observation. Ultra-low dispersion ED glass The SV503 70ED telescope objective features an SFPL-51 ultra-low dispersion glass ED element, which virtually eliminates chromatic aberration. This gives ED doublet lenses excellent color correction. dual focuser The 1:10 micro reduction is ideal for astrophotography, allowing you to quickly and accurately focus. You can easily see beautiful starry clouds and get clear astronomical photos right away. SMC coating Anti-reflection: Increases light transmittance and suppresses internal reflections that cause flare and ghosting. Provides crisp and clear images. Can be used as a finder scope The SV503 70ED telescope has a small diameter of 70mm, so it can be used as a finder scope. specification: 1.Type: Refracting telescope 2.Objective lens aperture: 70mm 3.Focal length: 420mm 4.Coating: FMC 5.Focal ratio: f/6 6.Resolution: 1.97" 7.
