One for the astronomy and gadget buffs.. Trying to think what to get bro-in-law for Christmas, am toying with the idea of a head torch with red filter (apparently it disrupts your night vision less) . Have to check with sis that he doesn't have one already - I know he has a little red hand torch. The cheapest I've seen was on an angling website, for £15 which is about as much as I'd want to spend - anyone got any specific recommendations? And if not that, any other suggestions, perhaps with an astronomy theme?
