The ZWO ASI290MM At a Glance


Experience Astro-imaging With The ZWO ASI290 Monochrome Camera 

Optimized Sensor Technology

Capture enhanced images with two or three 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. With approximately 2.13M effective pixel back-illuminated CMOS image sensors IMX290LQR and IMX291LQR 

Impressive Astrophotography Performance

Engineered with a low read noise of 1e and fast HD imaging at 170 fps, images are remarkably free of interference! AR coated windows stops light from bouncing off the lens, increasing the throughput of the system and giving you clearer images.

Efficient Mechanics 

Connect and guide at faster and smoother rates! The ASI290MM uses a USB 3.0 interface that provides a 5 GB bandwidth, allowing your camera to run at 82.2 fps and 170 fps at max resolution. This camera also comes with an ST4 guide port so the camera can directly connect to your mount for autoguiding.

      ASI-290 fast and accurate

      This was used for imaging the three bright planets in fall 2018. Everything worked flawlessly. Using the USB port it is fast. It is easy to get 100 fps with whatever exposure fits up to the 10ms, obviously longer exposures limit the frame rate, but the relationship stayed linear. The control of the gain worked well. The "all-sky" lens that came with it was helpful when testing the camera operation out of the box before taking it out at night. Resolution was a good match with a Meade 10" f/10 and a Powermate 2.5X. The noise performance was as expected for this sensor. The build quality was nice, and everything fit together without effort or adjustments. Good purchase for the money.
