The device works using a fixed horizontal brass rod and a vertical rod holding a gold leaf.

Long before the invention of the achromatic lens, Gregory solved the issue of edge diffraction on non-achromatic lenses with a revolutionary design that introduced the use of mirrors (before Gregory, telescopes used mainly lenses). The decision to forgo lenses for mirrors, eliminated edge diffraction to produce crisp, upright images. The introduction of mirrors also allowed for the construction of larger instruments, with greater magnification. The ability to see objects fainter and farther away laid the foundation for advancements in astronomy.
