ZWO ASI662MC 2.1 megapixel USB3.0 color astronomy camera for planetary and lunar astrophotography.
Dedicated astronomy cameras split into two broad jobs. Small, fast planetary cameras capture thousands of frames to freeze moments of steady seeing on the Moon and planets, while cooled deep-sky cameras use larger, low-noise sensors for long exposures of nebulae and galaxies. Key specs are sensor size, pixel size, which should match your telescope's focal length for a sensible pixel scale, read noise, and whether the sensor is cooled to cut thermal noise. Decide between monochrome with filters or a simpler one-shot color sensor. These cameras suit imagers ready to move beyond a DSLR toward higher sensitivity and control. A practical tip: match pixel size to focal length before chasing megapixels. An oversampled or undersampled setup wastes resolution, so use a pixel-scale calculator with your specific scope, and start with a one-shot color camera if you want faster results with less processing.
