Frequently Asked Questions
Chromatic aberration, where different colours of light focus at slightly different points, causing colour fringing. Also, large lenses are very heavy and difficult to support without distortion.
Galileo Galilei, who used one to make groundbreaking astronomical observations in 1609-1610.
Yes, but primarily for specialised purposes like astrophotography of bright objects, as guide telescopes, and in high-quality, smaller amateur models. Large research telescopes are almost all reflectors.
A refractor (refracting telescope) uses a primary lens to bend (refract) light. A reflector (reflecting telescope) uses a primary mirror to bounce (reflect) light.
A telescope that uses a glass lens as its main component (the objective lens) to gather and bend (refract) light to form an image.
Refracting telescope is usually technical, academic, historical in register.
