Narrowband CN and TiO filters are used to identify carbon stars among red giants. We have identified 195 carbon stars, extending up to 15' from the center of the galaxy. We present well-calibrated R and I magnitudes for all stars. The large field surveyed allows a reliable foreground estimate of M stars, leading to a C/M ratio of 0.64, when giants as early as M0 are counted. Analysis of the photometric properties of the C star population reveals a narrow MI distribution with a mean MI of -4.69mag, with a dispersion of ±0.28. IC 1613 has, for its absolute magnitude, a normal number of C stars. Description: Observations of IC 1613 were conducted on two consecutive nights, on 1998 December 9 and 10, at the 2.5m Du Pont Telescope on Las Campanas, Chile. The wide-field (WF) CCD with an unvignetted field of 24' in diameter was used. With a Tektronix 2048×2048 CCD, the pixel scale is 0.78"/pixel. Our CN and TiO interference filters are centered at 8150 and 7700Å, respectively, with a bandwidth of 300Å. File Summary:
