The QHY-8Pro doesnt have any amp glow.
This model has the ICX-453 Sony Superhad, which is a progressive read out.
The ICX-413 is the two field version that has a very small amount of amp glow on the sensor.
This is due to the Sony design of the CCD, and the amp is on for just over 3 seconds with each exposure made, which is insignificant when your exposures are 5 or 10 minutes each time.
A check of what sensor is in any camera from any manufacturer should describe which type of sensor is in it.
