Such sad news Allan’s passing. I had known him for decades as he did his post grad degree at Lancaster University, my home city. His lectures were unique and never to be forgotten. I heard him give a 1 hour talk at a BAA meeting at Alston Hall in Preston, the title was ” The History of Astronomical Photography and Spectroscopy”, he never used a single slide or image in delivering that talk, it was spellbounding for all in that room. He will be greatly missed by all that knew him. Allan Chapman RIP.
