When Planets Cross the Sun

Although transits of planets across the Sun are rare (only Mercury and Venus orbit the Sun closer than us, and so can transit the Sun's disc) amateur astronomers can observe, record and image other kinds of transit, which are very much more frequent. Transit is in two parts, the first telling the fascinating story of the early scientific expeditions to observe transits. The second part is for practical observers, and explains how to observe transits of all sorts - even transits of aircraft as they fly between the observer and the Sun!

Responses and Remedies

Light-pollution is the modern scourge of optical astronomy. More and more observing sites are being lost as the glare of city lighting blots out the night sky. Professional astronomical observatories are located far from cities, but amateur astronomers often do not have this luxury.

This book considers the two available strategies open to astronomers - get rid of the light pollution by lobbying Authorities and Standards Organisations, and minimise its effects by using the correct instrumentation. The book contains an extensive detailed catalogue of deep-sky and other objects that - despite what one might believe - can be seen from variously light-polluted sites, for practical observers.
