  My ebook, “A Breathtaking Window on the Universe: a guide to the Roque de Los Muchachos Observatory” will be on sale in few months. It explains why the observatory is on La Palma and how a telescope works, and gives details of each telescope, plus many anecdotes and over 60 photos. You can get full details on this site as soon as they’re available.
