SVBONY SV48P Astronomical Telescope 102mm Large Aperture Tube OTA Refractor Telescope Focal Length 663mm FMC AR Coating Dual Speed Focus for

102mm large diameter: SV48P has a large diameter of 102mm. It has excellent light gathering properties and can brighten images. Suitable for astronomical observation. F/6.5 short focus ratio: f/6.5 short focus ratio provides a wider field of view. Since more light can be collected, the image will be brighter and the object you are observing will be clearer and easier to observe. Very useful for wide-angle astrophotography. Dual-Speed Focus: Fast focus allows you to quickly move the focus wheel to roughly focus on your target, and slow focus allows you to more finely adjust focus for optimal image clarity. AR anti-reflection coating: can reduce reflection and increase transmittance. Improve brightness. Image clarity and contrast. It provides a better visual experience. Combining the two: Photographic solution: When used with the SV705C (IMX585) astronomical camera, you can obtain EAA imaging ideal for low-magnification wide-area visual surveys and supplementary photography (system data support with highest sampling precision must be provided by the PM) Visual solution: When used with the SV231 chromatic aberration correction filter, a single ED OTA chromatic aberration control level can be achieved. The effect is the same as SV503. Excellent service and manual: Comes with Japanese manual. We are committed to providing affordable products that combine quality, performance and better user experience for children, youth, adults and amateur astronomers.
