There are some differences between the two telescopes. In a reflective telescope, the mirror allows the light to bounce and focus a small area, while in the refracted telescope, the lenses in its structure focus the light as it moves towards the other end. On the other hand, while chromatic aberrations in the refracting telescope, there is no chromatic aberration in the reflective telescopes; they are easy to install and inexpensive. However, they must be at the same temperature as the outside air to decrease the image quality's efficiency.
