Color Filters included This kit includes four color filters. The filters simply thread onto the bottom of the eyepiece and allows you to bring out surface structure and details in lunar and planetary surfaces.

Think of it like a pair of sunglasses for your telescope. The moon can be so bright in a telescope that without filters it can be uncomfortable to view. Also it will substantially bring out more detail and contrast of lunar surfaces.
