Hello.
Please see attached an image I recently took on Apogee Alta F16000 using Ekos.
The lower half of the image is filled with ugly artifacts. Since the image captured for focusing does not seem to contain similar defects I suspect they occur during long exposures like this one which is 5 minutes long. I am not ruling out the possibility of sensor defects but I have not had a chance to look at the sensor itself because the camera has a mechanical shutter. The previous owner of the camera used Maxim DL 5 for imaging with this camera. I have not yet used Maxim DL with this camera to find out if similar artifacts emerge. If anyone out there has any idea please let me know. Thanks in advance for your help.
