Description
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. The SVBONY super 1.25" 40 mm plossl eyepiece engineered with 4 element design and offers a generous 40 degree apparent field of view. It is awesome for perusing the sky and finding things like constellations, clusters, and galaxies in the field of view. The planetary eyepiece has an safety undercut design to prevent the telescope objective lens from slipping out. The length of the eyepiece can be changed by disassembly. Removable rubber eye guard for those wearing glasses and glasses.
