Calver, F.R.A.S." is a scientific publication likely written in the late 19th century. The book focuses on providing guidance for the use and construction of silvered-glass reflecting telescopes, emphasizing their advantages over other types. It serves as a resource for both amateur astronomers and practical observers keen on understanding telescope selection, silvering techniques, and operational adjustments. The opening of this work introduces the nature of silvered-glass reflectors and their growing popularity among astronomers. It highlights the benefits of such telescopes, including reduced chromatic aberration and ease of use compared to achromatic telescopes. The text details considerations for suitable atmospheric conditions and offers practical advice on telescope adjustments, mirror polishing, and the intricacies of telescope construction. With references to practical observations and a variety of technical instructions, the opening assumes a guide-like tone, aiming to convey the joy and satisfaction derived from using well-crafted optical instruments.
