Minus 7 in Queensland? Golly, where are you - maybe somewhere around Stanthorpe (Granite Belt area)? That's cold for that latitude. It gets to minus 12C at times on my place in Cooma, but you'd kind of expect it - it's very close to the snow country.
As far as this system goes, it relies on an 802.11 (WiFi) network rather than Bluetooth. Better range - especially through walls and glass/aluminium doors. What I've used here is from onOne Software (
http://www.ononesoftware.com/detail.php?prodLine_id=38), and is only available for iPod, iPhone, iPad and a host laptop (being either Windows or Mac-based) out near the scope to run the server software on. You download and install the free server software (no setup as such), connect your camera via USB and away you go. Fire up the iDevice and select the found server - voila. Simple-as and very clever.
The nutty thing is that I now run two distinct 802.11 networks
from my scope now - one for DSLR Remote and the other for my SkyFi control for the Argo.
I don't have an observatory at my place in Sydney BTW. I go out and set up the whole shebang every time. I'd like an obs here but don't trust people in my area not to break in at every opportunity.
