NGC 2903 is a strongly barred galaxy harboring a nuclear starburst. We have mapped the 1.28$\mu$m Pa-$\beta$ recombination line using CRSP, the KPNO long-slit near IR spectrograph, on the KPNO 1.3m telescope. The map shows that star formation is strongly concentrated about 3" or 150pc to the north of the nucleus. We discuss the advantages and disadvantages of our observational technique compared to conventional narrow band and Fabry-Perot imaging.
