Sheridan, Let there be no doubt whatsoever that I find the Handbook ESSENTIAL. It is always by my side when I go outside to observe and is the framework on which I plan my observing for the forthcoming year. My first task on receiving the new edition each October is to extract the information that I expect to use and present it in a format that suits me. For me the Handbook is absolutely indispensible.
I hadn’t seen JM’s piece but the top part looks like a header that may (or may not) have been inserted after your query. If the piece had omitted a reference to the BAAH then that’s certainly odd. I value the Handbook greatly though there are now many online resources as well. How much use I make depends on clear skies which vary enormously over a year and also on lunar phase.
