Welcome This issue has a couple of themes running in parallel, of camera optics and astronomical photography. Both are explored on a range of scales. The camera optics perspective begins with a review of the recent Good Picture event where Chris Dainty discussed the lens systems in mobile phone cameras. We then move on to the optical (and physical) characteristics of a 1969 camera lens before exploring the imaging chain of the 8.1m aperture Gemini North telescope. The Soligor 800mm looks more like a telescope than a camera lens and its use in this context is explored. A review of a literature paper explores the imaging science limits of modern day professional scientific imaging of a double star, dealing with the optical characteristics of the atmosphere. As always, the Imaging Science Group newsletter welcomes your thoughts on any of this. Or indeed any aspect of Imaging Science.
