New Edition of Hints on Silver-Glass Reflecting Telescopes Manufactured by Mr. G. Calver, F.R.A.S. with Directions for Silvering, Adjusting, &c.

A practical guide for anyone interested in constructing and using silver‑glazed reflecting telescopes, this work explains why the silvered‑glass reflector has become a favorite among serious amateurs. It outlines the optical advantages of a well‑figured speculum—free from chromatic aberration and capable of delivering sharp lunar and planetary views—while also comparing its performance to that of achromatic refractors. Readers learn how the larger apertures and compact design of reflectors make them especially useful for deep‑sky observing.

The book moves on to detailed, step‑by‑step instructions for silvering the glass, aligning the optics, and mounting the instrument securely to minimise tube currents. It also offers seasoned advice on choosing observing sites, judging atmospheric steadiness, and getting the most out of clear, mist‑free nights. Whether setting up a new telescope or refining an existing one, the guide provides the hands‑on knowledge needed to enjoy crisp, vivid views of the night sky.
