From: TerryMoselaol.com Date: Sun, 4 Sep 2005 21:01:36 EDT Subject: Death of D. Sinden, Radio & TV Hi all, 1. Many of you will have met, or know of, David Sinden, who took over the Grubb Parsons optical company operations when the company closed. It's with great sadness that I have to inform you of his death, after a longish illness, last Monday, 29 August. After many many efforts I was finally able to get him to come to Belfast to give a totally fascinating lecture to the IAA a few years ago. He was Chief Optician at Grubb Parsons for many years, and was responsible for many hundreds of optical systems, both lenses & mirrors, including some of the world's largest optics, such as the 4.2-metre (165-inch) mirror for the William Herschel Telescope, the 3.9-metre (153-inch) mirror for the Anglo-Australian Telescope, and the new corrector plate for the 48-inch Oschin Schmidt at Mount Palomar. He had recently done a lot of work on restoring or renewing the optics for the various telescopes at Armagh Observatory. A true amateur astronomer, as well as a telescope optician sans pareil, he will be sorely and sadly missed. RADIO AND TV 2. Special this week, BBC R4: Dava Sobel will read from her new book, 'The Planets', Mon-Fri, 9.45-10.00am and 24.30-24.48am. 3. Mon/Tue 5-6 Sep, 24.25am, BBC TV: The Sky at Night on the 2DF and Sloan surveys of the night sky. Clear Skies, Terry Moseley
