Reflector Vs Refractor Telescope. Since the Refractor telescope has a closed tube, they do not often require any cool-down period (unless there is a huge temperature difference) Primary Mirror: The large, concave mirror situated at the rear of the telescope that collects and reflects incoming light towards the secondary mirror

Between a reflector and a refractor telescope of the same size, a refractor telescope will generally have a longer focal length allowing for a more detailed and magnified image but a smaller field of view The biggest refractors tend to be only around 6 inches in diameter
The primary mirror is responsible for the telescope's light-gathering power and resolution It's only when I started shopping that I discovered there are also reflector telescopes based on mirrors rather than lenses Astro-Imaging Capability (Winner: High-Quality Refractors) Most amateur astrophotographers prefer the simplicity of a high-quality apochromatic (APO) refractor telescope.
