ASI174MM Mini camera integrates Sony IMX174LLJ / IMX174LQJ 1/1.2″ sensor (11.3 mm x 7.1 mm). It is the first model in the “mini”-series of cameras from ZWO. This camera has 1936 x 1216 pixels with a pixel size of 5.86 μm x 5.86 μm. It camera provides 12-bit ADC and its QE peak is 77%.
Astrophotography Performance
ASI174MM 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.
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.
High Sensitivity
Sensitivity is the first thing we considered. This is of course a crucial ability when looking for a star to guide on. So, from the beginning, we were set on using monochrome sensors to design our guide cameras. Because monochrome sensors have much higher sensitivity than their colour counterpart. Luckily the ASI120MM Mini, ASI290MM Mini and ASI174MM Mini all have very high QE peak value – about 80%, which can detect more stars in view and shorten the exposure time in guiding.
Each of the cameras have their own strength and depending on what you value in a guide camera, one might be better for you than the others.
