The ZWO Camera ASI 294 MC Pro Color Is a versatile and powerful astrophotography camera, equipped with the Sony IMX294CJK sensor. Thanks to the back-illuminated CMOS technology this camera offers exceptional sensitivity and dynamic range, capturing even the faintest deep-sky objects with clarity and detail. This makes the ASI 294MC Pro ideal for Astrophotographers seeking excellent image quality, without the complexity of a monochrome camera.
With this camera, all at short exposure times of only 30 seconds impressive deep-sky photos are taken - without active cooling. Thanks to photostacking faint nebulae and galaxies can be captured even under light-polluted conditions.
Key benefits
✔ High sensitivity for deep-sky objects - Thanks to the Sony IMX294 CMOS sensor and a quantum efficiency of 75% at 530 nm.
✔ Fast image transfer via USB 3.0 - Also compatible with USB 2.0.
✔ High Full Well capacity - With 63.700 e- The camera prevents over-radiation of bright stars and delivers a excellent signal-to-noise ratio.
✔ HCG mode for reduced noise - At a gain higher than 120 (12 dB) the readout noise is reduced to less than 2 e-, which provides extremely detailed, low-noise shots.
✔ Widely applicable for various telescope systems - Suitable for refractors, Newton reflectors and Ritchey-Chrétien telescopes with a f/4 - f/7 focal ratio.
✔ Compatible with duo narrowband filters - Ideal for photography of nebulae in light-polluted areas.
Advanced image quality without compromise
The ASI 294MC Pro comes with a AR clear glass filter, allowing infrared to pass through completely. For blocking IR light is a separate IR-cut filter needed. Thanks to ROI support only part of the sensor can be used for higher frame rates - ideal for planetary photography.
Although the camera no active cooling has, this not necessarily For standard deep-sky shots. This makes the ASI 294MC Pro an excellent choice for mobile astrophotographers which is a lightweight and powerful camera search.
Note: Limitation in H-Alpha photography
The ASI 294MC Pro is ideal for RGB recordings of deep-sky objects, but by the Bayer Matrix of the color sensor may cause artifacts when using H-Alpha narrowband filters. As a result, this camera is Less suitable for pure H-Alpha shots. For pure H-Alpha nevelopnames, a monochrome camera recommended.
