IMX462 has lower readout noise, and very high QE in near Infrared spectrum. by using 850nm filter, this CCD can be used as NIR only camera. monochrome ( ASI290MM) is better than color version(ASI178MC, ASI294MC), for solar astrophotography: Extended IR response: Advantage for planetary astro IMX327 is very similar to IMX462, except with a lower 60 FPS Jupiter using CH4 filter astrosurf Amateurastrophotography Astrowl
