We present a third generation instrument using a photon counting camera (IPCS) based on an GaAs photo cathode that can achieve quantum efficiency up to 28%, comparable to a thick CCD, but without readout noise. This system is 10 times more sensitive at the Hα wavelength than previous Fabry Perot system used at the Observatoire du mont Mégantic. In terms of S/N ratio, the system outperforms CCD for extremely faint fluxes, included AR coated low noise thin CCDs. This system offers up to 1k x 1k pixels which is the largest monolithic IPCS. An original cooling system is used for camera based on a Ranque-Hilsh vortex tube. The real-time centering is done by a scalable DSP board. FaNTOmM is the association of a focal reducer (PANORAMIX: the 1.6m mont Mégantic OmM telescope focal reducer), a Fabry Perot etalon and an IPCS. Preliminary results obtained with the 1.6m mont Mégantic telescope are presented.
