QHY8PRO amp glow question

Started this thread about what to buy next
http://www.iceinspace.com.au/forum/s...ad.php?t=74024
and Greg (GREGBRADLEY) mentioned the possiblity that the QHY8PRO might have amp glow. Is any one doing DSO astrophotography with a QHY8PRO experiencing amp glow?? If so at what exposure settings?

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.

Hi Stephen, Amp glow is definitely not a problem with the 8Pro. You can look at a lot of images taken with this and the QHY8 on my website. No Glow.
