ASI071MC Pro first sub after connecting pixel issue

Post by AntMan72 » Tue Feb 19, 2019 10:53 pm

Sam sent you a PM as i remember a post somewhere about this issue. I contacted ZWO support and they do not know what it is. Before i send it back to the store i would like your opinion please. This is on a new ASI071MC Pro

odd pixels or distortion after connecting to SG pro or any other capture and taking the first shot. no matter if its 1 sec or 1 minute. Then the next shot no matter how long the pixelation or distortion is gone. I have attached to photos the first one has the distortion and the second taken 3 seconds later does not. Please advise what this is and how to correct it.

Hi,
Sorry for the problem.
Are you sure Sam had discussed this problem? I asked Sam, but he do not remember.
We checked the raw image you send to our support. But also not sure what happened. We suspected it might be some kind of liquid or crystallization or something. So we need the your help.
1, Please take pictures under a warm temperature, and check if it happens.
2, If it still has, please remove the protected panel, Just like clean the sensor, and check the sensor with a magnifier。
You can also email to me: chad.cao(at)zwoptical.com
Thanks

OK thanks for the help. It has not come back again and does look like some type of crystallization of moisture. I am going to try and trigger it again by cooling down fast and other scenarios.
