In recent weeks I have had quite a number of emails regarding the QHY8 Cooled CCD camera.

Thinking about which way to reply I decided the best initial test that could be carried out was that of displaying the dark noise generated by this camera. I set about creating a set of Master dark files and have attached them below. They have been quite heavily stretched to show up any defects and I will leave the results to you.
The files are displayed in order: 60sec, 120sec,300sec, 600sec, 900sec, 1200sec and 1800sec.

Summing up my responses. My real conclusion about the questions asked is " I would buy one again in a heartbeat. I believe it is the best bang for your buck available in the Astro imaging market today."

These are my thoughts and I have no connection in any way with QHY or their cameras appart from owning one.
