QHY42 Pro

The QHY42Pro is a cooled scientific CMOS camera designed for both astrophotography and scientific research. Let’s explore its impressive features: Sensor and Sensitivity: The QHY42Pro uses the Gsense400 Scientific CMOS sensor with extraordinary characteristics. It boasts an impressive 95% peak quantum efficiency (QE), including 79% UV QE and excellent NIR response. The sensor’s read noise is remarkably low at 1.7e-. With a relatively large pixel size of 11μm, the QHY42Pro offers a 2k x 2k array for capturing detailed images. The sensor size of 22.5mm x 22.5mm ensures a good field of view even at longer focal lengths1. Dual Readout Modes: The QHY42Pro supports three readout modes: Single 12-bit high gain channel output: Achieves 24 FPS at 12 bits. Single 12-bit low gain channel output: Also operates at 24 FPS. Dual 12-bit high gain and low gain output mode (HDR mode): Provides 12 FPS at 12 bits. The HDR mode combines high and low gain channels to enhance dynamic range and
