Abstract

The character of the instruments used in the observation can affect the data obtained and further data processing. This study presents the instrumental characterization of the ZWO ASI 533MM Pro CMOS camera from bias, dark, and flat calibration images on BVRI filters. After taking flat image data, we found that the image was over-exposed on filters B, V, R, and I. The image on filter B was overexposed when the exposure time was 0.7 seconds, filter V when the exposure time was 0.35 seconds, filter R when the exposure time was 0.6 seconds and filter I when the exposure time was 28 seconds. From bias image data taken with 32 microseconds exposure time, obtained an average value of 397.7 ADU, a median value of 398 ADU, and a standard deviation of 2.3.
