So how does one photograph a Bat after dark?
On a small pond called Elephant Head pond just south of Green valley, AZ a set was designed to allow the photography of bats flying into a pond to get a drink of water after dark. The set used an Infrared trap and high speed flash to illuminate the bates as they fly by. Cameras with an assortment of different focal lengths are focused on the area of the beam and turned to take images every 8 to 15 seconds. The cameras take one image after another, all will be black accept when a bat triggers the flash. Here are a few shots of what the setup looks like before dark.
Cameras on tripods pre-focused and ready for the dark and the evening shoot

Infrared TV sets connected to elevated and ground level infrared cameras to monitor area after dark from about 10 yards away from pond, popcorn anyone?

Final adjustments on the flashes and IR trap.
With a lot of luck, aiming the camera correctly, and the bats cooperate, you can get a great image of a bat with reflection in the water.
