Telescopic Gated Intensified Camera


Another configuration used for ultra-faint imaging of meteors is the attachment of the gated camera to a large telescope. The goal of such a setup is to examine wake and fragmentation in smaller meteors.

telescope gated

In this setup the gated camera was coupled to a 0.4m f/4.5 Newtonian telescope. With this configuration the field of view is 24x19 arcmins. The intensifer was set to produce exposures equivalent to 0.53 ms per gating signal. The faintest detectable stars are near +12 and the faintest meteors are near +10. Some examples of events are shown below:
