Something odd appeared when I was using my ZWO ASI 2600mm camera tonight.

A vertical "bar" of lightness shows on the left side of the screen. It is very distinct.

Any ideas what this is? I tried restarting my ASIAir, but that didn't help.

Does it happen in dark frames too? Smells like a hardware issue. That may even be correctable with darks, but still not good.

Yes, I included a dark frame in that link. Hmmm I may need to contact ZWO as this camera is only about 4 months old

Let us know what they say, you might try a different cable but it doesn’t look good…

Ok well today I unplugged all cables and replugged in for everything in the setup and the problem was resolved.

What USB cable are you using? I can recreate this problem if I turn down the usb speed to minimum and use a very poor usb cable. 

 

Also check if the Asiair is receiving enough power.

Remember, that the Asiair needs to send 5V through the usb cables, beside the 12 volt plugs.

That's why the big Amp requirement on the power adapters. Needs to be 12 volts and 3-5 amps. 5amp is the safe bet. 

Poor electric power to the unit will cause all sorts of issues, including slow usb, slow/disconnecting wifi/ corrupted images and even poor guiding if it can't send the pulses right to the mount.

The ASIAir has enough power. I'm using the recommended 12v PS that ZWO sells for this.

I use a GEM45 and, for some reason, the ASIAir doesn't communicate well with it over USB, so we have to use a USB hub in between the ASIAir and the GEM45 mount.

If this issue shows up again, I'll buy a new USB hub and see if that eliminates it
