Description
We report finding charts and accurate positions for 432 compact H{alpha} emitting regions in the Local Group Galaxy M33 (NGC 598), in an effort to isolate candidates for an SS433-like stellar system. The objects were extracted from narrowband images, centered in the rest frame H{alpha} ({lambda}6563A) and in the red continuum at 6100A. The atlas is complete down to V=~20, and includes 279 compact H II regions and 153 line emitting point-like sources. The point-like sources undoubtedly include a variety of objects: very small H II regions, early type stars with intense stellar winds, and Wolf-Rayet stars, but should also contain objects with the characteristics of SS433. This extensive survey of compact H{alpha} regions in M33 is a first step towards the identification of peculiar stellar systems like SS433 in external galaxies.
