I received my copy of International Halley Watch Amateur Observers' Manual for Scientific Comet Studies by Stephen J. Edberg last night. It is well written and has a wealth of information reguarding comet observation techniques. Topics include: Visual Observations Photography Astrometry Spectroscopic Observations Photoelectric Photometry Meteor Observations The book is essential for anyone expecting to contribute to the International Halley Watch program but even if you have only a casual interest the Ephemeris and star charts give nighly positions of the comet from June 1985 through May 1987. The book can be purchased from Sky Publishing Corporation 49 Bay State Road Cambridge, Mass 02238-1290 Cost $9.95 Fred Mendenhall
