Product Description
This product has been discontinued. We recommend seeing the ASI220MINI as a great alternative.
ASI290MM Mini camera integrates Sony IMX290 1/3" sensor (5.6 mm x 3.2 mm). It is a new model in the “mini”-series of cameras from ZWO. This camera has 1936 x 1096 pixels. The pixel size is 2.9 μm x 2.9 μm. This camera provides 12-bit ADC and its QE peak is over 80%.
ASI290MM mini camera offers you very good performance for planetary imaging as well as for guiding. Low read noise, high dynamic range, AR protective window and much more are just some of the key characteristics that set it apart from the competition.
290Mini vs. 290MM
Compared with the ASI290MM camera, the new ASI290MM Mini has a sleeker design, less weight, and it can reach focus at the same position as an eyepiece.
USB2.0Port & ST4 Port
USB 2.0 PortMini camera has one USB2.0 type-C port. Type-C port is very popular in mobile phones, as it doesn’t matter which way you connect it (unlike for example type-A or type-B).
#USB-C to USB-A cable is required.
ST4 PortThe camera can be connected directly to the auto-guider port of the mount.
