Astrophotography Performance

ASI174MM mini camera offers you very good performance for guiding, as well as for planetary imaging (in monochrome). 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.

Large Field of View (FOV)

ASI174MM Mini is designed for large field-of-view guiding. This is very useful when looking for a star to guide on, using an off-axis guider (OAG). When you use an OAG-guider with a Ritchey-Chretien or Schmit-Cassegrain telescope, the hardest part is to find a suitable guide star. ASI174MM Mini has a larger 1/1.2″ sensor which means your FoV is 4 times bigger than that of the ASI120MM Mini. The large pixel size is a good match for higher f-number scopes, like those above, as well. 

174Mini vs. 174MM

Compared with the ASI174MM camera, the new 174-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 Port: Mini 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 Port: The camera can be connected directly to the auto-guider port of the mount.
