This is because reflectors use mirrors to gather and focus light, which can be made larger and lighter than lenses used in refractors. Reflectors use mirrors which can be shaped and combined to create larger apertures, while refractors rely on a single lens which can become very heavy and difficult to manufacture at larger sizes.
