The SBIG STF series provides very good cost/performance ratio with low noise and fast readout speeds. The STF series supports filter wheels and an optional off-axis guider for use with the SBIG ST-I camera. For higher cooling and adaptive optics support please see our STT camera line. The STF-402M is targeted at scientific applications includes an optional internal filter wheel supporting both photometric UBVC and LRGB imaging. The STF-1603M is essentially the same camera with a larger sensor. The STF-8300 includes the popular KAF-8300 sensor, an 8 megapixel camera with good sensitivity. The STF-3200M is the ultimate in sensitivity, with 85% peak quantum efficiency. The STF-8050 and STF-4070 are interline cameras with very strong cooling, capable of both very short and very long exposures.
