Features: Thanks to the back illuminated SENSOR structure and advanced pixel technology, the camera has extremely low readout noise and a large full well capacity (38ke -), especially in low light conditions. It is three times the size of the IMX485 sensor. Whether it's long exposure or high gain, the SV705C camera has no Amp Glow at all, ensuring completely highquality "dark" images. HCG digital noise reduction technology Adopting HCG digital noise reduction technology can significantly reduce readout noise and maintain high dynamic range. SV705C has a region of interest (Whips.) that can be set to automatic resolution, greatly improving the frame rate of planetary imaging. Its excellent performance ensures that planetary imaging is very easy. 3856 × 2180 @ 45FPS 1920 × 1080 @ 187FPS 128MB DDRII cache The SV705C has a builtin 128MB DDRIII image buffer. The advantage of an image buffer is that when the USB interface is not busy or interrupted, the memory will cache and transfer the image to the computer, so that frames will not be lost or damaged. This buffer also allows slower computers using USB 3.0 to capture every frame without losing it, even if the USB bus is occasionally busy with other peripheral devices. This buffer can also be used to run another camera on the same computer without USB transfer issues from SV705C. ST4 orientation USB 3.0 highspeed transmission Adopting USB 3.0 highspeed data transmission, it enables fast and efficient imaging of planets, the moon, and the sun. Notes: 1& 12289; Computer configuration requirements: If you want to use the SV705C camera to capture images through a telescope eyepiece. You need to purchase an eyepiece projection adapter.   Product specifications Specification Description Appearance structure interface CS thread interface M28.5 filter thread interface M42 female thread interface M42 male thread interface 1.25inch interface 2inch interface 1/4 threaded hole 1/4 threaded hole Minimum posterior intercept 6.5mm Protecting glass AR antireflection Shell material Aluminum alloy, anodized iron oxide gray, universal SV505C Overall dimensions General SV505C Hardware specifications sensor sony IMX585 data interface TYPE-B USB 3.0 interface Navigation star interface ST4 6PIN Navigation Satellite Interface cache DDR3,128M Software parameters ROI Center after switching BIN BIN1,BIN2,BIN3,BIN4 USB bandwidth limit 0,1,2 HCG Automatic opening Anti lag automatic continuous shooting function If an unexpected pause occurs during the reading of a certain frame, the system will automatically terminate the shooting of that frame after a certain period of time and start the next task, continuing the shooting task resolving power resolving power Drawing mode RAW8 RAW16 RGB24 exposure 20μs-2000s gain   Background level 0-255 contrast ratio 0-100 gamma Default 1 saturation 0-255 sharpening 0-100 white balance White Balance R, White Balance G, White Balance B Automatic white balance Adjust Display histogram R,G,B drive Local driver   ASCOM driver   Compatible system system Windows Mac OS Linux Raspberry Pie Chrome Electrical parameters Target surface size 11.18mm×6.32mm   3856×2180 pixel size 2.9μm* 2.9μm Frame rate 48FPS shutter type Rolling Shutter QE 0.9 Full trap 38.8Ke Readout Noise 6.5-0.7e ADC 12bit Accessories details 1 * USB 3.
