وصف
SV503 80ED telescope's objective lens features an S FPL-51 extra-low dispersion glass ED element, which virtually eliminates chromatic aberration. This results in the good color correction for an ED doublet lens.SVBONY SV154 26mm 2" telescope eyepiece, with 70°ultra-wide-angle viewing experience, is particularly useful for locating and appreciating wide targets such as star clusters and nebulae. An excellent choice for both beginners and experienced astronomers observing the Moon, planets, and deep space.SV188P uses a high-reflective dielectric coating that can achieve a reflectivity of 99%; more light means you will get brighter pictures.the SV182 finderscope helps you to locate and track the celestial targets quickly. Whether you are an amateur or professional astronomer, the scope will be the better choice to observe.SV128 Variable Polarizing Eyepiece Filter for Viewing the Moon and Planets.
