Sad to read the passing of John. For me he was one of the associations greats. He was for so many years at Winchester Weekends the star of the show. Each year we looked forward to hear about the next great telescope he was making.I also have great memories of visiting his house and workshops some years ago. To some it would be a scrap yard , to John anything could be turned into a telescope.I am proud owner of a very early focusing mount which I keep in pride of place at home. I will raise a glass to him at the next Winchester.
