The QHY5III290 with monochrome sensor is the perfect choice for users looking for a monochrome camera that allows you to record many images per second (thanks to the USB 3.0 computer connection), which has a large number of compact size pixels (so you can record the smallest detail even using not long focal length telescopes) and that has still a not too high price. Thanks to the latest Sony IMX290 STARVIS Exmor-R back illuminated sensor, the QHY5III290 camera is outstanding for Moon and planets imaging at a high magnifications!
The QHY5III290 uses the Sony CMOS IMX290 STARVIS Exmor-R latest generation monochrome sensor. This sensor offers great technical specifications:
- high resolution (1920 x 1080 pixel)
- compact pixels dimensions (2,9 micron)
- extremely low readout noise
Thanks to electronics with USB 3.0 connection to control PC, the QHY5III290 allows you to record many images per second (up to 120 fps at full resolution - note: the recorded fps number also depends on the control PC speed). So you can get video composed of more images that, processed with special software for astrophotography, enable you to achieve better results!
These advanced technical features make it very good not only as a planetary camera but also for those looking a guide camera. It has a built-in ST4 port (with LEMO connector, known to be very robust - the ST4 guide cable on the mount side instead has the classic connector for connection to the most popular mounts) that allows direct connection to the mount. In addition, the high quantum efficiency makes the camera very sensitive and therefore it will be easier to find the guide stars.
The QHY5III290 camera has the design of the previous QHY5II series, with 31.8mm diameter accessory shape. In this way QHYCCD got better efficiency in heat transfer to the outside of the camera body. This particular design also provides a very low back focus makes the camera ideal for off-axis guiders.
