The SELEX experiment (E781) is 3-stage magnetic spectrometer for a high statistics study of hadroproduction of charm baryons out to large xF using 650 Gev Sigma-, pi- and p beams. The main features of the spectrometer are: a high precision silicon vertex system, powerful particle identification provided by TRD and RICH, forward Lambda decay spectrometer and 3-stage lead glass photon detector. An experiment overview and spectrometer features are shown. Reconstructed charm states and results on Lambdac, D+ particles and antiparticles produced by Sigma-, pi- and p beams at xF>0.3 and asymmetry for Lambdac are presented.
