Getting i in the air (Score 2, Informative)

I am used to tie my telescope on my bike (not the motorized version, the legs-powered). And guess what, I am also used to tie my ibook G3 with starry night pro started with night vision enabled. I suppose I could wire up my techno mp3. But I like silence and the long lasting night on one eco battery. Isn't the idea more airy ?
