How did Gregorian telescopes work?
The James Gregory Telescope is the largest working optical telescope in the UK and is still used by the School of Physics and Astronomy for research in collaborative projects such as SuperWASP and the study of super massive black holes and their impact on galaxy structure.
The reflecting telescope, first suggested by James Gregory, meant that the problem of chromatic dispersion was avoided, and that the telescope size was smaller and more powerful. Gregory's design uses a metal mirror to reflect light rather than a glass lens that refracts the light.

James Gregory was a Scottish mathematician and astronomer, born in November 1638 in Drumoak, near Aberdeen, Scotland. He was educated at Marischal College (later part of the University of Aberdeen), where he graduated in 1657. Gregory is best known for his description of the first practical reflecting telescope, now known as the Gregorian telescope...
The Gregorian telescope is a type of reflecting telescope that was first published by Scottish mathematician James Gregory in 1663. It is known for its unique optical design, which utilizes a concave secondary mirror to reflect and focus light. According to the Gregorian design, the primary mirror must have a hole at the center, and the secondary m...
James Gregory did not invent the first reflecting telescope, but he did make significant contributions to its design and development. Gregory’s involvement with telescopes began in the early 1660s when he was a professor at the University of St Andrews. During this time, he published a book called Optica Promota, which explored various aspects of o...
James Gregory described his reflecting telescope design in his 1663 publication, Optica Promota. This design is now known as the Gregorian telescope. The Gregorian telescope design uses a parabolic primary mirror and a concave secondary mirror with an elliptical surface, which corrects spherical and chromatic aberration. Although Gregory lacked the...
Feb 25, 2015 · James Gregory, inventor of the reflecting telescope and Fellow of the Royal Society, was the first Regius Professor of Mathematics of the University of St Andrews, 1668–74. He attempted to establish in St Andrews what would, if completed, have been the first purpose-built observatory in the British Isles.

The Gregorian telescope is a type of reflecting telescope designed by Scottish mathematician and astronomer James Gregory in the 17th century, and first built in 1673 by Robert Hooke. James Gregory was a contemporary of Isaac Newton, and both often worked simultaneously on similar projects.
The James Gregory Telescope is the product of two decades of planning and construction. Almost all components of the telescopes have been manufactured in Scotland. The telescope has now been in operation for more than fifty years.
This Demonstration shows the principle of a telescope designed by the Scottish mathematician and astronomer James Gregory in the seventeenth century; it was first built in 1673 by Robert Hooke. The parameters and are the semiaxes of the ellipse, and the equation of the parabola in polar coordinates is The ellipse and parabola have a common focus.
