The ZWO ASI290MC COLOR is an exceptional camera for lunar, planetary, solar and even deep sky imaging. It uses a 1/2,8″ CMOS Sony IMX291LQR color sensor that has a 2,13Mpx resolution (1936 x 1096). This sensor, with a read noise as low as 1,0e, can take pictures at a maximum of 170FPS at full resolution, ideal for planetary imaging. Sony has developed the approx. 2.13M effective pixel back-illuminated CMOS image sensors IMX290LQR and IMX291LQR with improved sensitivity in the visible-light and near infrared light regions for industrial applications. A new 2.9 µm-square unit pixel has been developed that combines a back-illuminated structure with technology for improving near infrared sensitivity to further enhance picture quality at low illumination while at the same time realizing Full HD cameras for industrial applications. This realizes two or more times the sensitivity in the visible-light region and three or more times the sensitivity in the near infrared light region than that of the existing Sony product (IMX236LQJ). It comes with high speed USB 3.0 port, standard 2″ M42 x 0.75 internal thread interface, 0.25″ tripod thread mount on the rear, an AR window and an ST4 Guide Port.
