Vai al moduloZWO ASI294MM Mono – Sony IMX492 CMOS Camera for Deep Sky, Moon and Planets
The ZWO ASI294MM is the first non-cooled CMOS camera equipped with the Sony IMX492 sensor in Four Thirds format. It's a versatile camera, suited both to lunar and planetary photography and to deep-sky imaging, thanks to modern Sony back-illumination technology.
The 4.6 μm pixels ensure high sensitivity with short exposure times; you can also switch to "unlocked" mode for 2.3 μm pixels and even higher resolution. Despite lacking active cooling, the camera delivers low-noise images thanks to HCG mode (read noise below 2e with gain above 120) and a high full well capacity, which prevents the brightest stars from burning out.

- 23 mm sensor diagonal, 4144 x 2822 px resolution (11.7 MP)
