I picked up an iOptron iEQ30 for eclipse chasing and imaging with my smaller camera platforms and last night was the first time I used it for imaging (really the first time the mount was used for other than testing at the PC). I used the mount with an AT65EDQ, Canon T3, QHY5-II guider and usb-focus for the focuser. Everything was working great. Centering, focusing (perfect v curves), guiding.
I then started the sequence, and everything was fine until the sequence went to take the first frame in the target. At that time I received the following message "EDS_ERR_TAKE_PICTURE_CARD_NG" from the Canon T3. Note than I had no problems getting frames from the Canon from all the other functions including frame a focus shots of the same duration (180 seconds) as the target sequence. I was running the Canon T3 form a powered USB hub with the guider and focuser and had no issues. I swapped out USB cables and had the Canon T3 all to itself on one PC port...the same thing.
The Canon T3 was set to Manual,bulb setting and the SD card was inserted and had lots of room, is working and in any case, I had the camera set to open the shutter without an SD card. I don't use the Canon a lot for imaging, but even when I did, I did not see this message before.
Here is the log file

Any ideas on how to correct this?
Thanks,
