Vai al moduloToupTek 571C PRO – Cooled CMOS Color Camera for Astrophotography
The ToupTek 571C PRO is a high-performance cooled CMOS astrophotography camera designed for exceptional sensitivity, low noise and superior image quality, even under extremely low-light conditions. The Sony IMX571 APS-C sensor features a 28.3 mm diagonal, 3.76 µm pixels and a high resolution of 26 MP (6248×4176), enabling wide-field imaging with outstanding detail — ideal for galaxy clusters, extended nebulae and complex deep-sky structures.
The advanced dual-stage TEC cooling system provides a true temperature delta of 35°C below ambient, significantly reducing thermal noise during long exposures. The integrated 512 MB DDR3 memory ensures stable data transfer and prevents frame loss, even when using USB 2.0 outputs.
Low-light Performance
With an excellent SNR1s of 0.14 lx, the IMX571CJK delivers remarkable sensitivity, making it ideal for scientific-grade astrophotography. The real Full Well Capacity of 51 ke− allows a broad dynamic range, preventing bright stars from saturating during long exposures.
USB Connectivity and Integrated HUB
The high-speed USB 3.0 interface ensures rapid file transfer, making focusing and capture efficient even at full resolution. The camera offers:
- 6.8 fps at 6224×4168
- 63 fps at 2064×1386
The rear USB 2.0 HUB allows direct connection of accessories such as filter wheel, guide camera or electronic focuser, simplifying cable management.
Status Indicators (LED)
- PWR: Confirms proper power supply
- SYS: Confirms active connection to the PC
- TEC: Indicates Peltier cooling system activity
- FAN: Indicates cooling fan operation
Advanced Features
- 51 ke− Full Well Capacity for extended dynamic range
- True 16-bit ADC with 65,535 brightness levels
- Built-in anti-dew system
- Zero AMP Glow
- Software binning from 1×1 to 8×8 (sum or average)
