We have undertaken CCD observations of fie이 standard stars with H$eta$ photometric system to investigate the reliability of H$eta$ CCD photometry. Flat fielding with dome flat and sky flat for H$eta$w and H$eta$n filter was compared with that of B filter in UBV system and, from these, we have not found any difference. It was confirmed that there is a good linear relationship between our H$eta$ values observed with 2.3m reflector and standard values. However, H$eta$ values observed with 60cm reflector at Sobaeksan Astronomy Observatory showed very poor relationship. To investigate the accuracy of H$eta$ CCD photometry for fainter objects, open cluster NGC2437 was observed and reduced with DoPHOT, and the results were compared with those for photoelectric photometry of Stetson(1981).
