ASI290MC offers very good performance for astrophotography. Low read noise, high dynamic range, QE peak about 80%, AR protective window and much more.
Sony Camera Sensor IMX290LQR, IMX291LQR
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.
Diagonal 6.46 mm (Type 1/2.8) Square Pixel Array Colour CMOS Image Sensor
Back-Illuminated CMOS image Sensors with Improved Visible Light and Near Infrared Sensitivity that Support 1080p
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).
