I have some Sony Super HAD 2 starlight PAL/NTSC video cameras in use a security
cameras.
Nice cameras, no IR light needed at night.

Did hang one out of the window on a half cloudy night:

  starting at 33 seconds you see things move, planes? More near the end..

That inspired me to design and build a tracker for missile or laser gun control
that only needs a bright dot to lock on:

Again it shows a simple PIC is often cheaper faster better than GB memory media
players...
Especially when speed, weight and power consumption counts like in a missile.
If that fascist pig in the white house keeps at it, I may accidently open
source the code.
I mean the guy who has reporters from media that expose his lies shot at.
 F35 stealth my foot.
  F35 is just a tax payer money sucker.
