An intricate technical engraving of Herschel's Great Telescope. The structure is a massive wooden lattice tower with a triangular footprint. A large telescope tube is mounted on a platform (B) within the lattice. Various parts are labeled with letters: A points to the telescope tube; B is the platform; C is a small structure near the tube; D is a small house-like structure at the base; E is another small structure; F is a ladder; G and H are at the top of the lattice; I and U are at the base. The entire structure is shown on a flat, textured ground. W. Pitt Prin. Nat. Sculptor fecit.
