【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. 【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. [Suitable for beginners] SV503 70mm refracting telescope is suitable not only for experienced observers but also for beginners. Applicable to astrophotography, moon and planets, natural observation, nebulas and galaxies, etc. In addition, it comes with a 2-year worry-free warranty, so if there is any problem or damage with the product, please feel free to contact us. We will always do our best to provide warranty service. Thoroughly thought out design and high quality mechanical parts. 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 the ED doublet lens excellent color correction. dual focuser The 1:10 micro reduction is ideal for astrophotography and allows for precise focusing right away. 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.
