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)

ST4 Port: The camera can be connected directly to the auto-guider port of the mount.

I haven't had chance to use the camera

I haven't had chance to use the camera 'in anger' yet but all seems well with it. The larger FOV and camera sensitivity will make my OAG set-up much better! Service by George the owner is fantastic. Being relatively local to me, we arranged to meet so it saved on shipping costs and a trip to the store. Thanks! Gary. (aka astrophoto_canada@instagram)
