SV305 Pro camera is designed with ST4 guiding port.
lunar imaging and some bright deep space objects imaging.
The SV305 Pro uses an extremely sensitive IMX290 CMOS sensor.
This 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.
This buffer also allows a slower computer with USB 3.0 socket to capture every frame without loss even if the USB socket is occasionally busy with other peripherals.
This buffer also makes it possible to run multiple cameras using one computer without USB transfer problems.
A smaller region of interest ROI is read out from the sensor.
leaving the image scale of the object being imaged.
