Abstract

ANALYSIS he British Astronomical Association (BAA) has Jeremy Shears been a driving force in amateur astronomy for on what the British Tover 125 years and is one of the world’s leading Astronomical amateur groups. Now it is offering the option of digital membership, providing all the benet fi s of a Association can traditional subscription – but with our Journal and oe ff r, including a Handbook delivered digitally – from just £29.50. new and cheaper People join the Association for many different reasons: some observe the sky purely for their own digital subscription. enjoyment, while others make systematic obser- vations, recognizing that astronomy is one of the few sciences where amateurs can still play a role.
