    Thanks Robin. I like the newspaper idea. It appeals to the improviser in me (not to mention the skinflint!).

    Thanks Robin. That’s interesting. Can we put any numbers on this? What is the optimum size of a dew shield? I’m playing devil’s advocate, but that’s part of the fun!

    Well done indeed.

    It’s not exactly a recommendation, but I stopped subscribing to S&T a few years ago. Instead, I decided to try Sky News: The Canadian Magazine of Astronomy & Stargazing. It only appears bi-monthly and is not particularly voluminous. But is has a very spacious and calm style, is printed on heavy, quality art paper (as S&T once used to be) and I particularly enjoy the images it offers, many of which are superb. I rather like it.

    My father bought me a subscription to S&T, when I was starting out in astronomy, in the early 1960s. I found it pretty awe-inspiring, especially its full-page pictures; one of somewhere on the Moon’s surface sticks in my mind to this day. And frustrating to see all those telescopes advertised for sale, but only to the locals. It was like seeing an Aladdin’s cave without being able to go into it.

    When I became a teenager, the sub fell by the wayside. I didn’t take it up again until I was in my sixties. . .  and then dropped it again!
