ASI071MC-Cool Amp Glow

Curtis2010

The ASI071MC-COOL is my main astrophotography camera. and has always worked well. I use it with the ASIAIR Plus.

Recently, I wanted to test out the ASIAIR support for Sony Alpha cameras. So, I installed a Sony a6000 and tried it. That was successful, but when I switched back to my ASI071MC I got a problem very similar to amp glow (which I have never had with this camera).

Due to the camera swap, I thought it might be an optical train issue (like a light leak) so I removed the camera from the optical train and put the dust plug in the end of it. Snapped a pic and the same issue appeared.

Ive also tried swapping out USB 3.0 and power cable. No joy.

I also reset the ASIAIR and reinstalled current firmware. No joy.

Has anyone encountered a similar problem? Suggestions?

Unfortunately, I did not save the images from last night. I will test again tonight.

I did perform an additional test: I connected the camera to an ASIAIR Pro and the problem appeared to be eliminated (based on test images with lens cover in place).

I have switched the camera back to the ASIAIR Plus and the problem appears to be much less (test images with lens cover in place).

A test image I just made using the ASIAIR Plus is attached. Settings: cooling 0C, gain 90, exposure time 5s.

In an attempt to isolate the problem, I switched the camera to an ASIAIR Pro. The problem did not occur.

I switched it back to the ASIAIR Plus and the problem was no longer present.

My hypothesis is that some of the camera settings were corrupted by testing with the A6000 and that the process of swapping between ASIAIRs cleared the corrupted settings.

Completed an imaging session last night with no problems.
