Nice pictures. Can you provide some information on how you took them? In particular the exposure time and ISO.

Thanks, George

Hi George
Thanks. The camera has a sensitivity of 0.000005lx, which would be the equivalent of a little more how ISO 12500.

Martin,

Impressive!

To follow on from Georges question, what fps or duration
were you videoing at?

In fact, are these video frames or still frames from the WATEC?

Hi Andrew
It is the analog camera (25th frames per second.)
The camera is connected to the computer with a program (UfoCapture) that catches the Red sprites.
The program create a snapshot, video and several files for analysis.
