: Some sites, such as First Light Optics, offer PDF previews of the table of contents and introduction to give you a feel for the material before purchasing.

You will need a pair of glass blanks (typically BK7 Crown glass and F2 Flint glass). You will also need a series of abrasives, ranging from coarse Silicon Carbide (for rough shaping) to fine Aluminum Oxide (for smoothing), and finally Cerium Oxide for polishing.

The physical book traditionally included a companion CD-ROM featuring specialized Excel spreadsheets. When using updated iterations or modern open-office tools, these spreadsheets allow you to substitute alternative glasses (like Ohara equivalents) and automatically recalculate your parameters. Core Phases of Building a Refractor

: One of the most shocking revelations in Remer's book is the physics of optical error. A mirror surface must be figured four times as accurately as a lens surface to achieve the exact same wave-front accuracy. This is because light reflects off a mirror (doubling any surface error) but passes through a lens, where the refraction dampens the effect of minor physical deviations.

By matching the curves of these two lenses perfectly, the red and blue wavelengths of light are brought to the exact same focal point, yielding crisp, high-contrast images of the moon, planets, and double stars. 3.

By combining Norman Remer’s structured, methodical engineering insights with modern testing shortcuts, any patient astronomy enthusiast can craft an instrument capable of delivering breathtaking, razor-sharp views of the planets and the moon.

: Spanning 408 pages , it covers the entire process of building an achromatic doublet lens from scratch.
