ZWO ASI715MC Color

The ASI715MC is a high-sensitivity color camera equipped with a 1/2.8" sensor and an 8.46-megapixel resolution. Featuring Sony's advanced STARVIS technology, this camera boasts ultra-low readout noise (0.72e) and exceptional sensitivity, making it perfect for detailed astronomical imaging of planets and smaller deep-sky objects, as well as for microscope photography.

The camera's compact 1.45μm pixels make it an outstanding option for imaging without the need for focal extenders or Barlows. This feature is particularly advantageous for lunar photography, as it allows you to maintain a wide field of view while still achieving excellent resolution.

256MB DDR3 Buffer

The camera features a USB 3.0 transmission interface and comes with a built-in 256MB DDR3 cache to provide stable and secure data transmission.

Performance Diagrams

Readout noise encompasses pixel noise, circuit noise, and ADC quantization noise. Lower readout noise levels are preferable as they enhance image quality. The ASI715MC exhibits very low readout noise, which decreases further as the gain value increases. This characteristic makes the ASI715MC particularly effective for capturing clearer and more detailed images.

Quantum Efficiency

The QE (Quantum Efficiency) curve and readout noise are crucial metrics for assessing a camera's performance. Higher QE and lower readout noise are essential for enhancing the image's signal-to-noise ratio, leading to clearer and more detailed captures.
