In addition to his professional research that has appeared in various technical journals, for over twenty-five years Julius has written extensively on the subjects of lunar and planetary astronomy. He has also mad considerable contributions to the existing literature on methods and techniques for making visual observations of the Moon and planets with various astronomical instruments and accessories. For many years his articles have appeared in Sky and Telescope, Astronomy, Journal of the British Astronomical Association, Journal of the Association of Lunar and Planetary Observers, Star and Sky, and elsewhere. He has also published comprehensive A.L.P.O. observing manuals on Saturn, Venus, and the Moon so that enthusiasts all over the world could plan and execute useful research programs. Julius has frequently been a guest speaker at local and national astronomical gatherings and his efforts as a liaison between amateur and professional planetary scientists has helped improve the significance of A.L.P.O. observational work.

This new series is designed especially for practical amateur astronomers who not only want to observe, but want to know the details of exactly what they are looking at. Saturn is the second largest planet in the solar system, and the only one with a spectacular ring system that is easily visible from Earth. Saturn is a gas-giant, a huge world dominated by its rings and a retinue of moons. It is probably the most commonly observed and imaged planet for amateur astronomers, because it is always changing - the moons move visibly in the course of an hour, the weather systems on the planet change, and the orientation of the ring alters this way and that. The concept of the book - and the series - is to present an up-to-date detailed description (part one); and then (part two) to consider how best to observe and record the planet, its moons and its ring system successfully. "Saturn and How to Observe It" is a mine of information for all levels of amateur observers, from the beginner to the experienced.
