United StatesAn excellent camera for the money. I got this to fill a dual purpose of planetary and deep-sky and it does the job. Calibration will be difficult, even with a full set of frames the amp glow pattern is still partially visible if an image is stretched very hard.
United StatesI love this camera. So far I've done a few projects and the resolution is amazing. It's very sensitive too. I use narrowband filters to block light pollution with exposures in the 240s to 300s range. There is serious amp glow, but I've calibrated it out.
United StatesThe quality camera for this price.
United StatesI’d heard of this issue but was shocked when it hit...yikes. But some excellent advice from ZWO to make sure you calibrate with a master dark exactly set to the same gain as your light, and without optimizing or using bias frames [PixInsight] and it goes away. Phew... Shooting at Unity Gain, 111 for this camera.
OPT same-day shipped the 183 pro and it arrived 2 days later via USPS. I bench tested the camera and it appeared to be working correctly. However, be advised that this relatively new CMOS camera requires the latest drivers from the ZWO website be installed. This includes both the ASI_camera_driver and the ASI_camera_ascom driver for Windows 10. I found that both SGP 3.03 and Sharpcap 3.2 will run this camera with the updated drivers.
The camera is perfect for high-resolution imaging with shorter focal-length setups, such as my William Optics Z61. Everything worked right out of the box, cooler gets to -20C without breaking a sweat, and the low-noise images that result are detailed and easy to stack. What little amp-glow there is calibrates out with dark frames with no problem. Looking forward to doing narrow-band imaging with it soon! Typical good OPT ordering experience: ordered on Wednesday, had it on Thursday.
