SVBONY SC571CC APS-C Color Cooled Astronomy Camera

26MP APS-C Sensor: Deep-Sky Imaging with 3.76µm Pixels

At the heart of the SC571CC is the SONY IMX571, an APS-C sensor with a 28.3mm diagonal that provides a wide field of view on refractors and corrected reflectors. The 6244×4168 resolution and 3.76µm pixels strike a balance between image scale on mid-focal length instruments and high-resolution sampling. With a peak QE greater than 80%, the back-illuminated CMOS architecture maximizes photon collection, essential for capturing the subtle details in faint galaxies and emission nebulae.

Dual-Stage TEC Cooling: 35°C Below Ambient for Clean Exposures

Thermal noise is the primary obstacle in long-exposure astrophotography. The SC571CC integrates a powerful dual-stage thermoelectric cooling (TEC) system that actively reduces the sensor's temperature by approximately 35°C below the surrounding air temperature. This aggressive cooling dramatically suppresses dark current, allowing you to take multi-minute exposures with a clean, low-noise background and build reliable dark frame libraries for calibration.

Zero Amp Glow & 1.14e- Read Noise for Clean Calibration

Beyond cooling, the SC571CC is engineered to deliver exceptionally clean raw data. The camera's circuitry eliminates amplifier glow, a common source of bright gradients in the corners of long exposures, ensuring flat fields are uniform from edge to edge. When operating in high conversion gain mode, the read noise falls to an impressive 1.14e-, preserving faint signal that would otherwise be lost in the noise floor of less sensitive cameras.

16-bit ADC and 512MB Buffer: Smooth Gradients at 13.3 FPS

Image data is processed through a true 16-bit ADC, providing 65,536 levels of gray. This extensive bit depth produces smooth tonal transitions in bright objects like the core of the Orion Nebula (M42) while preserving subtle details in surrounding faint structures. To handle this data stream, a 512MB DDR3 buffer prevents frame drops and ensures stable data transfer over USB, even when imaging at the maximum full-resolution frame rate of 13.3 FPS.

17.5mm Back Focus & Universal Software Integration

The SC571CC is designed for broad compatibility with modern imaging setups. It features a standard M42×0.75 female thread for connection to filter wheels, off-axis guiders, and correctors, with a fixed back focal distance of 17.5mm. The camera is supported across Windows, Mac, Linux, and Raspberry Pi operating systems, allowing seamless integration with popular acquisition software like N.I.N.A., SharpCap, and APT.

SVBONY SC571CC vs. ZWO ASI2600MC Pro: A Shared Sensor Core

The ZWO ASI2600MC Pro is a leading competitor that utilizes the exact same SONY IMX571 sensor. Consequently, the core imaging capabilities—26MP resolution, 3.76µm pixels, 16-bit ADC, and >80% QE—are functionally identical between the two cameras. Both cameras also feature a 512MB DDR3 buffer and similar cooling deltas.

The primary distinctions often lie in physical design and ecosystem integration. The SC571CC specifies a fixed 17.5mm back focus, which is a standard distance for many setups. The choice between them may depend on your preference for a particular brand's software drivers, support, and compatibility with other accessories in your imaging train.
