The ASI290MM Mini camera integrates Sony IMX290 1/3″ sensor (5.6 mm x 3.2 mm). The camera has an array of 1936 x 1096 pixels. The pixel size is 2.9 μm x 2.9 μm square, and provides a 12bit ADC with a QE peak over 80%.
The ASI290MM Mini boasts a USB2.0 type C port, so the USB can be plugged in any direction. It also has an ST4 port so that the camera can be hooked directly to the autoguiding port of a mount.
This is a great camera for planetary imaging, and also an excellent guide camera thanks to its fantastic QE and small lightweight body.

ASI290 mini is designed for precisely guiding. 2.9um pixel size can give you a higher arcsec/pixel than 224 or 120 camera. Which means in same guide scope, 290mini can detective slighter movement of stars. ASI290 mini can improve about 30% guide precision than 120mm.
ASI174 mini is designed for Big FOV guiding. This is very useful in OAG to looking for a guide star. When you use OAG guider working with Ritchey-Chretien or Schmit-Cassegrain telescope, the hardest part is to looking for a guide star. ASI174 mini have 1/1.2″ big sensor which means you can have a 4 times bigger Fov than 120mm.
