Remote operations of cameras
over very long distances isn't actually something new.
Still, it might be of interest for some to learn that
this can be done with very ordinary means. Here is what
A standard PC
connected to the internet in your home "control-centre"
laptop or notebook with a tethering program installed
for camera control. I use PK_Tether for my Pentax
dongle for connection of your laptop/netbook to the
webcam built into or connected to your laptop/netbook.
Software for Remote Desktop Control installed on both
computers. I use TeamViewer that is freeware for private
Download and installation of the TeamViewer software was
easy and completely trouble free. I chose to install the
full control package on both computers: Thus, I can
control my computers both ways and, fortunately, there
is no requirements that the operating systems must be
identical. Thus, I can use my Dell XP laptop in the
"control-room" and my Acer WIN7 notebook in the field.
start TeamViewer on both computers and set "allow
control" on the field computer and "take control" on the
control computer and follow the on-screen instructions
on establishing computer identity/name and password. In

the control computer.
With the webcam running and pointing
in the same direction as your camera, it is now just to
sit comfortably in your control-room waiting for the

And if you cannot wait to see the

Of course, transfer of image
files in the 10 MB class may take its time this way. But
since desktop control is so complete, you can also
manipulate and upload your files by any other means that
your installed software allows.
And now, off to the telescope with my
netbook and camera.....
