Webbfocal length of this system and the F/ number? Is this a fast or slow system? Answer: The focal length is 3 x 1500 millimeters = 1500 millimeters, and F/ = 1500/254 = 5.9. It is a slow system because F/ > 3.0.

Telescopes are made longer to reduce chromatic aberrations in their lens or mirrors. The longer the telescope the less curvature of the lens and less chance for chromatic aberrations. OK, that may be why, but what does that mean? the problem w jon stewart youtube
