This aggressive cooling dramatically lowers thermal signal, resulting in an extremely low dark current of just 0.0022 electrons per pixel per second at -20°C. Combined with its zero-amplifier-glow design, the camera produces exceptionally clean and easily calibrated raw frames, even on multi-hour exposures.\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\u003e14.5mm Short Back Focus (SBFL) Design\u003c\/h3\u003e\n\u003cp\u003eThis SBFL (Short Back Focus Length) version of the QHY600 Pro is specifically engineered for complex imaging trains. With a back focus distance of just 14.5mm, it provides critical space for accessories like filter wheels, off-axis guiders, and rotators while still meeting the strict spacing requirements of field flatteners and reducers.
