SV601 Microscope can work well with SV305 Astronomy Camera. you just need to use a 0.91” to 1.25” Adapter to easily connect. You can capture every detail of the specimen by Using SV305, the image is clear and sharp. Welcome to explore the micro-world with SV601 Microscope and SV305 Astronomy Camera.

• BSI CMOS sensor; SV305 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;
• 128MB DDR buffer; 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;
• Any area ROI support; 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; allow arbitrary resolutions to be set;
• SV305 planetary camera compatible with Windows system; Linux system; Mac OS system; and Raspberry Pi system; Windows driver 1.3.7 version; support ASCOM driver; PHD2 guiding software; not support Phone system;
• Long exposure can reach 30 minutes; high-speed; medium-speed; 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.
