I did try a Dell D630 30ft away from the house in the garden, with a CCD attached and it seemed to work fine when accessed by Remote Desktop and a Wifi connection. It happily sat there taking 5s exposures for me and displaying them. I didnt even need to move my Hub from the other end of the house – I will probably add a repeater when I use it in anger (theres minor issue of putting a pier in, adding the mount/scope and adding an observatory to be overcome yet) or add a couple of ethernet cables to the trunking carrying the mains out there.
I’m not sure why more people are not using Remote Desktop. What dumb error am I making? Security? 🙂
