Yeah I think it is the way with this hobby. I too, get why do you find it so interesting questions. But I must admit my daughter gets pretty excited and has a look with me, but she hasn't developed the stamina yet to withstand the cold (yes it is cold up here, well for us northerners it is anyway), or the mozzies, for more than hour or so. But thats ok, her interst is very keen. I spent about an hour explaining the reason why some things are red and some are blue in the photo's I've shown her from this forum and the hubble site etc. Towards the end I was surprised to realise she actually got the whole red-shift idea stretching the wavelengths. Was very cool.
