I have three ASI cameras. an ASI120MM-s, 120MC-s and an ASI 290 color. I am using an ASI290 color as my main imaging camera and an ASI120MM-S as a guider. Issue is worse with the 290. It will not allow me to come to focus, without reconnecting. The cycle continues. I have no issues with power. I am not given any other warnings. But when trying to focus, if the image indicator stops (green bar lower right), a disconnect is coming. It reconnects and now I have to reenter the camera info. Ughhh, Please help.
