SVBONY SV305 Telescope Camera CMOS Digital Eyepiece USB 2MP 1.25 inch Astronomy Camera Dynamic Observation for Telescope Planetary Viewing Photography

  • This telescope camera uses an extremely sensitive back-illuminated CMOS sensor.
  • IMX290 sensor has very high QE and very low (0.7e-) read noise.
  • which improved sensitivity in the visible-light and near infrared light regions for industrial applications.
  • The benefit of the image buffer is that the memory will cache the image and transfer it to the computer when the USB interface is not busy or being interrupted.
  • and the frame will not be lost or corrupted.
  • The SV305 astronomy camera has ROI function.
  • A smaller region of interest (ROI) is read out from the sensor.
  • leaving the image scale of the object being imaged unchanged.
  • low-speed three output frame speeds are optional.
  • matching different computer hardware to achieve a more suitable reception speed of the hardware. Meet the basic needs of astronomy enthusiasts for planetary photography.
