Please help - 'ASICameraException' from Unexpectedly in VideoMode when starting exposure
Posted: Wed May 12, 2021 6:51 am
Dear Admin,
Dear fellow astrophotographers,
I kindly ask for support. I use SharpCap for imaging and the last two nights I see one and the same error which prevents me from acquiring data and decided to ask for help.
Here is information for my system:
- Camera - ZWO Asi 2600 MC-PRO;
- Guiding camera - ZWO Asi 224 MC;
- PHD2 guiding on an iOptron CEM70 mount;
- Laptop used for telescope and camera control - Intel Core i5-3210M@3.1 GHz, 3MB cache, 4 GB Ram, Windows 10
- USB connection used - USB2
- version of SharpCap - 3.2.6480.0
- I use the latest version of ZWO camera drivers.
Mount control is connected to one USB2 port and the two cameras and a focus motor are connected to another USB2 port via the hub of the mount. All the equipment is powered by two power adapters - one for the mount which also powers the 224 MC and the focus motor and one dedicated solely to the 2600 MC.
Here is the problem that I observe - last two nights I targeted an object and left the system to image. In the morning I found out that it has taken several images and after that the images were not saved to the disk and updated on the screen. However SharpCap is performing as taking images - as the image acquisition progress bar is moving and is resetting. I image through Live Stack - there I have set the frames to be stored and reset every 60 minutes.
This morning when I went to collect my gear I found the same problem - about 10 images were taken, stacked and saved to the disk. After that the camera has continued to act if it was taking images but after the acquisition timer expires - image was not acquired, nor stacked, nor stored on the disk. Error message was not shown as well.
I clicked on the Cameras tab and at that moment in time cameras were not showing. I hit close camera. Then hit refresh camera list and the cameras showed up. I connected to the 2600 MC and it was working.
I have observed this problem some time ago on the ZWO Asi 533 MC-Pro as well but didn't act at that moment in time. The ASI 533 was connected directly to the laptop back then - so I guess the problem shows itself no matter if an USB hub is used or not.
I checked the logs as suggested on the forum. Here is the first error message that I find:

Thank you in advance!
