The SV231 color correction filter is designed with full thread and standard size to compatible with different types of telescope. High transmittance means high level of transparency, allows a significant amount of light or energy to transmit through it. You can use the SV231filter with SV48P telescope for astronomical observations without color difference to obtain the most exquisite details of lunar craters and planetary surfaces. 6x Magnification With 6x magnification, the SV182 finderscope helps you to locate and track the celestial targets quickly.
