There may be an alturnative to the normal all sky cameras for astreonomy in that Ive been looking at the HERO models of camera (
http://gopro.com/hd-hero2-cameras/) which are waterproof etc but to date couldnt give live feed. However I see now there is coming a WIFI pack that you can get live feed from your camera direct to an IPAD or IPhone

This is the advert blurb :-
Wi-Fi-enable your HD HERO2 or original HD HERO camera with the Wi-Fi BacPac™ and Wi-Fi Remote.
The Wi-Fi BacPac attaches to your HD HERO2 camera to enable long range remote control via the Wi-Fi Remote, smartphone or tablet running a free GoPro app. Waterproof and durable, the Wi-Fi Remote enables complete control of multiple HD HERO2 cameras at a time.
When paired with the Wi-Fi BacPac, the HD HERO2 also supports live preview, viewable from your smartphone or tablet via the GoPro App.
Could be very interesting
