How do these cameras do on an OAG? Also why did you go with a USB2 and not USB3 on the AIS174MM Mini?

because this is for guiding
and we think USB2.0 is enough for guiding

Thanks for the info, I figured it was something like that but thought I would ask since the camera may be used for planetary work.

I am trying to post a question regarding the ASI290 guider port pin out....when using a ST-4 cable, PHD software gets bad calibration data.

I checked the wiring diagram and find that ZWO guiders, although claiming and illustrating a ST-4 pin out, use totally different pin out than ST-4 protocols on my SBIG guider ST-i.

Actually you are compatible with Orion or Vixen, not SBIG....

My mount is a Takahashi EM-400 with the new guider port and RD-12 communication cable.

SBIG pin 1 +RA
ZWO pin 1 N/C

SBIG pin 2 +DEC
ZWO pin 2 GND

And so on...

Looks like a full cable reversal 1 for 6, 2 for 5, 3 for 4, 4 for 3, 5 for 2 and 6 for 1.

I did not find a place to post this

Which one of us is correct?

The ST4 port on ASI camera is compatible with ASIAIR
just the line order of Takahashi is different from others
so you have to make a special cable
