For applications requiring higher sensitivity and frame rates over raw resolution, the camera supports on-chip pixel binning. In 2x2 binning mode, four pixels are combined to create a larger 7.5µm x 7.5µm pixel, boosting the full well capacity to an immense 320,000e-. The camera also supports a 3x3 on-chip binning mode for 12-bit, high-speed applications.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eAdvanced Air and Liquid Cooling for the 150MP QHY411M PRO\u003c\/h3\u003e\n\u003cp\u003eMaintaining a stable, low temperature is crucial for minimizing thermal noise during long exposures.
