An awesome full frame OSC camera!
I recently got this camera and was able to image with it a few times. I wanted a full-frame OSC camera for galaxy season as well as broadband targets throughout the year, and I am very impressed so far! I use a $500 telescope (Orion 8" Astrograph) with this camera and both work surprisingly well together. I would suggest getting a IR-Cut filter if you plan on imaging an object near a very bright star though so you don't get star halos.

I'm very happy with this camera
Although I have had this camera for only one month, and haven't had much clear weather for actual sky testing, I am very happy with what I have seen so far. It is a technically fairly advanced camera, and I wouldn't recommend it for a beginner, but for someone with some digital astro-imaging experience, I find it quite exciting. It is my first full frame astro camera. I have not use SharpCap before (the camera control software recommended by QHY), but I find it powerful and pretty easy to learn and use. I strongly recommending reading the online manual before trying to use this camera. Included in the package were the camera, a 72mm diameter lens cap, the Center Angle Adjustment Ring (pre-set to be square with the optical axis), a 2-inch IR/UV cutoff filter, a small metal tube that can hold a dessicant and screws into the sensor chamber so it can be used for drying the air in the chamber, a 54mm male thread to 2-inch adapter so the camera can be slid into any 2-inch telescope focuser, a 2-meter long USB 3.0 cable to connect to a computer, and a power supply with a screw-on connection to the camera (100-240V, 1.2A, 50/60Hz input, 12V, 6A output). Other means to attach the camera to a telescope (such as a more dependable threaded attachment, which I used) or to attach it to a camera telephoto lens requires purchasing separately various adapters and/or threaded wide (48mm) extension tubes and/or 54mm filter holder and adjustment rings made by QHY. Since QHY128C package descriptions seem to vary by distributor, it would be good to verify exactly what is included in your package.
