Although it isn't an astronomy issue, someone may be able to give an
answer:
what is the reason for the time delay of a ToUcam (II Pro) when used as a
real time camera? The delay on my system is about 0.25 seconds,
independent
of stream format parameters such as output size (160x120 upto 640x480)
and
frame rate. I am using the VRecord program.




The combination of time taken sending over USB, storing in RAM, buffering
and per-frame display on the screen would equate to a near-constant delay.
