The ZWO ASI174MM Mini is a 1.25 inch guide camera with a large sensor and mid-sized pixels, making it a top choice for reliable, flexible guiding. Incorporating Sony's IMX174 sensor with excellent quantum efficiency and global shutter capabilities, its large 11.3mm x 7.1mm sensor gives you a significantly wider field of view than most traditional guide cameras. With a low read noise of just 3.5e and high frame rates of 5.4 fps at full resolution (1936 x 1216), the camera excels at precise guiding and planetary imaging. It's great for solar, lunar, and planetary imaging, with large pixels and sharp monochrome sensor that work beautifully with long focal length telescopes to capture fine details on the Sun, lunar craters, and planetary features.
