Multiple Readout Modes are special for QHY 16-bit Cameras (QHY600/268/461/411).  Different readout modes result in different performance. These readout modes are currently supported in the QHYCCD ASCOM Camera Driver, SharpCap and N.I.N.A. Readout Mode #0 (Photographic DSO Mode). This mode is suitable for most DSO imaging situations. Since there is a drop in the noise between Gain 25 and Gain 26 (unity gain), we recommend

To All QHY Users, Since March 2023, The QHY Mini Guide Scope will change from silver-green look to black-blue one, while the founction and price keep the same. The Mini Scope of new look can better suit the new QHY5III series planetary/guiding cameras.     Clear Skies, QHYCCD Team

Hello All QHY Users, From 2023, the top part of QHY268C will change to the shorter one just like that of 268M. In fact, you can get the “SBFL(shorter back focal length” version of 268C right now. The previous 268c has a back focal length of 17.5mm, and since it cannot connect to the scope without CAA, so it’s actual BFL is 17.5mm+6mm=23.5mm. Now after

Dear QHYCCD users, This announcement is to let you know that we will no longer reproduct the following models: Discontinued Model Date QHY168C 2022 QHY5L-II-C 2022 QHY5III290M 2022 QHY128C 2022 QHY294C 2022 QHY5III178C 2022 QHY367C 2022 QHY247C 2022 QHY163M 2022   For some of these models there will be “Clearance Prices”, which means you can get them for very low prices until the stocks run

QHYCCD, the world’s leading astronomical camera manufacturer, and Gpixel, a professional company specializing in the development of high-performance CMOS image sensors, have announced the successful performance of QHYCCD QHY4040PRO-BSI camera for astronomical imaging in the Corona Borealis Observatory, Ali, Tibet, China. The QHY4040PRO-BSI has been set up in the Corona Borealis Observatory, Ali, Tibet, China at an altitude of up to 5100 meters. “When seeing

Sony provides relative QE curves for the IMX571 sensor used in the QHY268M camera.  However, by comparing its response with a CCD of known absolute QE, the ICX694 used in the QHY22, we can determine the absolute QE for the QHY268M. The graph below from the Sony IMX571 datasheet shows the relative QE of the IMX571.The good news here is that this curve includes the

  After the launch of the QHY600 refrigerated CMOS with native 16-bit AD conversion, the QHY600 has received wide attention from astrophotography lovers. And the first batch of production products was ordered out of stock in no time. QHY600 uses SONY’s IMX455 full-frame back-illuminated chip, which provides a variety of readout modes. Therefore, in addition to astrophotography, QHY600 also provides some relatively professional functions. They

One of the most interesting stuffs of our website is–the home page banner will be left for our user’s photos! The top banner is planned to be changed every two or four weeks. You can send your works to our FaceBook Group: QHYCCD Astronomy Imaging  and better tag the topic#qhyccd, then we will pick up the best (or the most interest/creative) one from all photos

  If you’re a QHY user, you’re very welcomed to join our gallery with your wonderful astro photos! A gallery named by your name can be set at our website. If you want to have one, please sent your works with some necessary information: All images should be captured with QHYCCD cameras; The images you send should be of high-resolution; Please attach basic specifications of
