We are dedicated to informing, educating, and offering you the best optics available to suit your individual needs. It's pretty simple. Mirrors reflect light.
Lenses bend light.
The focal plane or focal point is the spot where the image you are looking at comes into focus. This point is more accurate and exact in refracting telescopes. Therefore the image you see is clearer, sharper and more crisp. Mirrors gather more light than lenses and the more light gathering ability you have the more image detail is revealed. Just imagine trying to read this text if the screen was not lit.
