Discovered a number of these on eBay while looking for military optical stuff. It appears to be a W.W.II vintage IR telescope. The Sniperscope and Snooperscope were of the same vintage. After receipt and installing a couple of "D" cell batteries it worked. You can hear a hum when the inverter is running and as soon as it stops running the image tube goes dark. That probably means the the high voltage capacitor is leaky. The vibrator does not start every time the button is pressed. The points may need to be cleaned.

This is a near IR (not thermal IR) telescope without an associated illumination source. It's intneded to see IR beacons or Aldis signal lights on ships with IR filters. It would also word to see the M-227 Signal Lamp Equipment SE-11 when the IR filter is in place. The C-3 does not have the ability to send a signal, only to see an IR signal.
T120 niperscope: IP-25
M1 Sniperscope: IP-25
M2 Sniperscope: IP-25
M3 Sniperscope: CRC-6032A (8000 +/- 1000 angstroms,800 nm, just beyone visible red light i.e. 700 nm)
The A version of the 6032 image tube is the same as the no letter version except specified to see lower light levels specified in lux. But that's a problem because lux is a visible light specification where the Weston Model 594 Photronic Cell is the basis of "visible" light. So suing light units may have been a mistake when working with a sensor for non visible radiation, even though it's just a little longer wavelength than red light.

There are 3 adjustments on the secondary mirror:
A large screw at the top allows access to the X adj,
A large screw at right of photo allows access to the
A hole in the front plexiglass plate allows access
to the Z adjustment.

Orion - 9x63 binoculars - When the objective diameter (63 mm) is divided by the power (9X) if the exit pupil size (7 mm) is around 7 mm then the binocs are designed to be used with night adapted eyes, like for looking at the stars or to see things on the ground you could not see with bare eyes. I once watched a dear swimming while being chased by a dog just after Sunset. Although I could not see anything with my bare eyes, I could see fine with a pair of 7X50 binocs. See my Binoculars page for more on star gazing binocs.
Celestron 8" Telescope with Equatorial wedge and tripod- This model has a clock drive but no computer control. It's big and heavy, not something you pull out for a quick 5 minute look up. Would be much better if used with a permanent pier. It takes quite some time to do a Polar alignment, but when done you can find about anything just using the hour angle and declination scales.
