Telescope design is the process of creating and improving the optical and mechanical systems of telescopes to achieve better image quality and performance. This includes optimizing the design of the mirror or lens system, the mount and support structure, and the control systems for pointing and tracking objects in the sky. Telescope design also involves considerations such as minimizing image distortion, maximizing light-gathering power, and reducing optical aberrations. Advances in telescope design have enabled astronomers to study the universe with unprecedented detail and resolution.
