A wide field telescope is a type of telescope that is designed to provide a larger field of view, or "field of vision", than other types. This enables the observer to gain an overview of their subject, often in one sweeping glance. Wide field telescopes are ideal for deep sky observing and long exposure photography, as they allow users to capture more detail and cover more area per image. These telescopes also offer increased light gathering capacity, making them a great choice for low-light conditions. Generally speaking, wide field telescopes are lighter and more portable than traditional refractors and reflectors, allowing observers greater freedom when it comes to choosing observation sites.
