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.
