SVBONY SV135 Telescope Eyepiece Zoom 7-21mm + SV231 1.25'' Killer Color Filter

Description: adjustable focal length;SV135 7-21mm zoom eyepiece equivalent to multiple eyepieces ;obtain higher magnification with short focal length;It could bring you a better observation experience in a comfortable situation with high-contrast imaging 18mm - 16.3mm comfortable eye relief; especially for eyeglass wearers ;designed primarily for viewing landscapes and astronomical observations of lunar surfaces; planets; nebulae; clusters; and diffuse nebulae fully multi-coated Premium eyepiece with superior edge and center sharpness than normal PLOSSL eyepieces; 6-Element 4-Group premium optical design for superior optical performance Standard 1.25" eyepiece;Equipped with a precision-made standard 1.25-inch lens barrel that is compatible with any telescope that accepts 1.25-inch eyepieces The filter is a filter 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. Standard 1.25-inch astronomical filter size specifications: meet the needs of telescopes of different apertures and cameras with different target surfaces. If you have ever been troubled by the edge chromatic aberration problem of your telescope, try this one, you may be pleasantly surprised.Excellent optical performance and color expression add color to your deep sky photography. Telescope filter prevents unwanted color banding in the blue spectral range; minimizes the most harmful blue wavelengths in out-of-focus areas. Optical density is greater than 4. It can effectively block light damage and reduce noise. The higher the filter cut-off depth; the smaller the noise and the higher the imaging contrast. High transmittance means high level of transparency, allows a significant amount of light or energy to transmit through it. Adopting AR anti-reflection coating, the pass rate is >95%, ensuring image quality and brightness. Improves the contrast and clarity of fast achromatic telescopes; ensures image quality and brightness; and obtains more observable light. Good performance coating; telescope color correction filter has plasma-enhanced dielectric coatings result in hard; scratch-resistant and waterproof filters. The filter can work effectively when the wavelength is between 300-1200/NM. Effectively blocking light damage and eliminating blue and purple streaks. The NIR is fully blocked up to 1150nm. This way, details on planets are shown much clearer when using CCD/CMOS-cameras, too. Full thread design; M28.5×0.6 specification; male thread; thread is not easy to wear; strong and durable; supports different types of filters for superimposed use. 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,you can perform astronomical observations without color difference. Compatiable with SV48P,you can observe celestial without color difference. about svbony
