ZWO ASI290MM

The ZWO ASI 290 MM is a versatile uncooled monochrome camera designed specifically for astrophotography enthusiasts. With its impressive features and capabilities, this camera offers a wide range of applications in capturing stunning celestial images.

One of the key uses of the ASI 290 MM is moon photography. Its large matrix enables the capture of detailed portraits of vast lunar areas. Additionally, with the application of appropriate filtration, it can be used for sun astrophotography. The CMOS sensor in the camera ensures low noise levels, making it ideal for capturing deep sky objects with exceptional clarity. Moreover, it can be used for guiding purposes, thanks to the inclusion of an ST4 port. The camera's f = 2.5 mm / 150° lens also allows for all-sky photography, capturing wide-angle views of the night sky.

The ASI 290 MM boasts impressive features that enhance its performance. It offers very low reading noise combined with high sensitivity, ensuring optimal image quality. The camera's matrix is protected with fast AR layers, allowing the infrared band to pass through. For those who prefer to block infrared, an IR-cut filter can be used. The camera supports a wide range of exposure times, ranging up to 2000 seconds, accommodating various astrophotography scenarios. Additionally, it comes with a wide-angle 2.5 mm / 150° lens, perfect for capturing meteors or creating time-lapse sequences. The manufacturer's software, FireCapture, is provided for free and enables automatic stacking and camera operation, making it an excellent tool for photographing nebula objects.
