Are eye-fi (wireless) SD-memory cards acceptable?
Hello:
I just wondered about the possibility of shooting astrophotos using a good Canon Rebel T2i with wireless card (eye-fi) and wirelessly loading it
onto the hard-drive of a laptop in the observatory or out in the field?
It is advisable? Does someone here know about the range of use (like even how far) too it will communicate before the signal breaks?
PS: does anyone know, if I used one of those power supplies for my T2i, like to power it from a car battery, how to make your T2i stay on without doing the auto power off?
