This is a system that I have thrown together for scanning the sky around my place. I love hanging out in the back yard on warm nights visiting with
friends while we gimbal the instruments around scanning the sky for high strangeness.
1)This is a FLIR thermal imaging camera which is sensitive from 7.5 to 14um. Mounted to the side of it is a Samsung camcorder which I use for
recording the video output of the thermal imager. I use the thermal imager as the primary means of locating objects in the sky because it has a
fairly wide field of view and can easily pick up blacked out aircraft at their service altitude. Objects don’t need to be producing gobs of heat to
be detected by the thermal imager. They just need to be a different temperature or emissivity than the background (which in this case is space). I
can even pull a temperature off of the surface of the moon with it. It has a cross hair displayed on the screen so I can just gimbal the telescope
around at my leisure and when I find something I put it in the cross hairs and then I know the telescope and other instruments are recording it too.
A nice feature is that I don’t even have to be watching the screen because there is an alarm that sounds when something different than the
background comes into view.
2)This is a Cannon camcorder that I chose specifically because of its excellent performance at low light levels. It has been extensively
modified to improve low light sensitivity even further. It is responsible for recording and displaying images from the main telescope. The main
telescope has a 13.1 inch primary mirror and is a Newtonian reflector. It is comparable in size to the optics used in early surveillance satellites.
I cannot however read the license plate of a UFO at 35,000 feet.
3) This is the body of an old web camera that I have gutted and installed a CDS sensor and a photo diode. The signal from the photo diode is
fed into channel 1 of the digital oscilloscope
(4) and the signal from the CDS sensor is fed into channel 2. This allows me to record the
exact nature of any pulsing (even into the MHz) of both visible light and near infrared light. The 3 inch telescope that these sensors are installed
onto makes a system that is incredibly sensitive. I often serendipitously pick up the tumble rate of dead satellites which are too faint to see with
the naked eye. Having the output of the different types of sensors feeding into different channels also allows me to perform a degree of spectral
analysis.
5) This is an ITT, Gen 3, night scope which I have aimed in the same direction as the other instruments. It is not presently hooked up to a
recording system because I primarily use it for initial object spotting as an alternative to the thermal imager.
6) This is a Telrad spotting site. It is similar to a heads up display allowing me to gimbal the instruments over to a visible object without
having to find it in the narrow field of view typical of a finder scope.
