Thanks for sharing that link Tony …. reading it makes me want a physical copy to join such books as Ouse’s Silent Tide by C.F. Farrar  and  Amateur Astronomer’s Handbook & Observational Astronomy for Amateurs by  J.B. Sidgwick,  Thanks to Martin too  for the Video link , Yes I still enjoy Will’s films too 🙂
