SVBONY SV48P 102mm Telescope, F6.5 Refractor Telescope for Adults High Powered Bundle with SV231 Color Correction Filter, 1.25'' Filter, Correct Edge Chromatic Aberration, for Astronomical Visual

SV48P 102mm f6.5 Astronomical Telescope has outstanding optics, high-quality mechanical components. Fitted with achromatic glass for good edge-to-edge viewing, fully multi green coated lens maximize light transmission eliminating false color. The 2.5inch Double speed focuser, for smooth operation, great feel and precise adjustability. This is a good telescope provides for astrophotography visual observers or nature watchers. The SV231 filter is specially used to correct chromatic aberration and color unevenness. It improves the color quality and contrast of the picture by eliminating chromatic aberration and enhancing color saturation. If you have ever been troubled by the edge chromatic aberration problem of your telescope, try this one, you may be pleasantly surprised. It can effectively block light damage and reduce noise. Standard 1.25-inch astronomical filter size specifications: meet the needs of telescopes of different apertures and cameras with different target surfaces. Adopting AR anti-reflection coating, the pass rate is more than 95%, ensuring image quality and brightness. P This way, details on planets are shown much clearer when using CCD or CMOS-cameras, too. The SV231 color correction filter can be used well before the focal point of the optical system, without any loss of sharpness, as a single filter in front of a binocular for a focal projection with digital cameras. Compatiable with SV503 or SV48P, you can perform astronomical observations without color difference. High transmittance means high level of transparency, allows a significant amount of light or energy to transmit through it.

• SV48P 102mm large aperture Telescope; large objective lens refractor telescope; high resolution; good light collecting ability; f/6.5 focal ratio; imaging brighter; more suitable for the observation of deep space celestial objective; product does not include field rotator, good astronomical observations can be achieved by choosing the right eyepiece; effective tracking, and post-processing
• f/6.5 short focal ratio; larger field of view; can collect more light; the image is brighter; and the observation target is clearer and easier to observe; very useful for taking wide-angle celestial photos
• Dual-speed focusing; fast focus allows you to quickly move the focus wheel to roughly focus on your target; while slow focus adjusts focus more finely for optimal image clarity
• Correct chromatic aberration; SV231 telescope filter prevents unwanted color banding in the blue spectral range; minimizes blue wavelengths in out-of-focus areas
• OD＞4; the higher the filter cut-off depth; the smaller the noise and the higher the imaging contrast
