ASI294MC Pro Problem

pbecker0127

Hello! Could you please have a look at the attached screenshot and offer your opinion and let me know what you think. The camera was pointed at a flatly lit sheet of grey cardboard with nothing attached to the camera. Only the protective glass in front of the sensor. Does this look normal to you? Please advise. Thanks in advance!

Have you tried to rotate the camera? If the black shade is in the same position then it's probably the image train causing it.

Also one thing you should know is that for ASI294mc pro camera, you should run at least 3 seconds of exposure when taking flats for optimal noise response.

Thanks for the response. There was nothing attached to the camera when i took the image. I wasn't aware of the 3 second lower limit on the flats. I'll give it a try. Thanks for the tip.
