21st Century Canon of Lunar Eclipses - Full Color Edition

In this review of the 21st Century Canon of Lunar Eclipses - Full Color Edition, the bottom line is straightforward: this is an authoritative reference for serious observers, educators, and eclipse planners who need detailed predictions and clear visual materials for every lunar eclipse from 2001 through 2100. The book's single biggest reason to buy is its combination of high-precision predictions based on the Jet Propulsion Laboratory DE430 ephemeris and the richly rendered full-color diagrams and maps that make complex data easy to interpret for long-term planning and study.

Key Features

• Complete century coverage: Contains diagrams, maps, and data for all 228 lunar eclipses occurring from 2001 through 2100, providing a single reference for the entire 21st century.
• High-precision ephemeris: Eclipse predictions use the JPL DE430 computer ephemeris, delivering accurate Sun and Moon coordinates for reliable timing and geometry.
• Full-color visuals: Full color diagrams and maps clarify eclipse geometry and visibility zones, making it easier to plan observations and educational demonstrations.
• Foundational explanations: An introductory section explains eclipse classification, visual appearance of eclipse types, and the Danjon Scale for assessing brightness, which helps contextualize the raw data.
• Technical discussion: Sections cover major contact definitions, Earth's shadow enlargement, coordinates of Sun and Moon, and Delta T so readers understand the assumptions behind the predictions.

Who It's For

The Canon is aimed at amateur astronomers, eclipse chasers, planetarium educators, and researchers who need a compact, century-spanning reference with both visuals and technical detail. Anyone preparing observing expeditions or curriculum materials will appreciate the full-color maps and the DE430-based timing data.

Those seeking a casual coffee-table book or general popular astronomy introduction may find this volume more technical than necessary; readers who prefer narrative histories of eclipses rather than predictive tables and diagrams should look elsewhere.

Pros & Cons

Pros

• Comprehensive coverage of every lunar eclipse in the 21st century for long-term planning.
• Uses the JPL DE430 ephemeris for precise Sun and Moon coordinates, improving prediction accuracy.
• Full-color diagrams and maps make complex geometry accessible to observers and teachers.
• Includes explanatory sections such as the Danjon Scale and Delta T to clarify technical context.

Cons

• The book is focused on technical prediction and diagrams rather than storytelling, which may limit appeal for casual readers.
