First light of FLI KL4040. The CMOS camera is so high speed and the exposure should have been 2 min instead of 5 min that caused the saturation against the core of bright stars and the nebula.
Also realize the black horizontal belt probably because of the nebula saturation. I need more test to gain confidence.
