We have studied the amount of diffuse light in two galaxy groups, Leo and HCG 44 through the detection of intragroup planetary nebulae (IGPNe). The emission line objects detected turned out to be compatible with background Lyα galaxies. We have estimated an upper limit to the amount of diffuse light in both groups assuming the presence of just one IGPN. This is in agreement with previous findings in other groups, and confirms that the amount of diffuse light decreases from rich galaxy clusters to groups.
