Sensitivity is a measure of the minimum signal that a telescope can distinguish above the random background noise. All other things being equal, a telescope of larger primary mirror or lens is more sensitive than one with a smaller primary. By guiding light through flexible, low-loss cables, these systems let telescopes send data to instruments with impressive precision and barely any distortion. 2 over the three-degree field of the telescope. As always, the projected performance is the result of optimizing scientific return.

This unique vantage point allows astronomers to observe celestial phenomena without the interference caused by. The range of a telescope is defined by how far into space it can effectively observe. This range is determined by several factors, such as aperture size, focal length, and the sensitivity of the detector (like a CCD camera).
