I just received my ASI120MM. I previously owned a QHY5. These images were taken in similar conditions, noticeable turbulence, same location and same optics. Perhaps my processing is too dark. I was expecting a 30% greater sampling rate and a better sensitivity, and that's done. I saw no offset, no random lines, no noise.
I'm very impressed by the sturdy housing of the ASI, too.
The USB cable is a good quality product (thick and stiff).
I used Firecapture, which runs perfectly with the ASI120MM and offers a lot of convenient features.
In other words, I'm very pleased with this camera !
