• At full resolution, the camera frame rate of SV505C can reach 93fps, and more frames can be captured at the same time. Especially in the case of bad weather, the shooting can be completed quickly by using the shooting gap time;
• SV505C has a QE of about 80%. It has extremely high sensitivity in the near-infrared region and extremely high signal-to-noise ratio in the dark environment. It is very suitable for photographing the surface details of Mars, Jupiter, Saturn and other solar system planets and the moon. The camera has extraordinary sensitivity in the infrared band;
• The SV505C has a 1/1.8" frame, and the chip area is 7.9mm x 4.5mm, which means that the photosensitive area is almost twice that of the sv305 pro. With the same telescope, a larger area can be photographed.

• The SC311 is designed with Sony IMX662 color CMOS sensor, which uses advanced STARVIS 2 technology. It has the characteristics of no amp glow and very low readout noise, higher sensitivity to red and near infrared(NIR) light；
• 2.4G WiFi technology let you can use 4 devices at the same time and share the fun of astronomy with your friends. Support Android and Apple systems, you can download them in the software store；
• 10M effective transmission sensing distance allows you to get rid of the shackles of the data cable, it is easier to realize the fun of astronomy observation outdoors；
• Built-in 2400mah lithium battery, it can support about 4 hours of continuous work, allowing you to have more time to focus on observations；
• Connect to our SvbonyAstro a software application designed by ourselves. You can do observation on your phone or pad and save them to the SC311 built-in TF card, and then easily share to social media.
• The SC311 camera can be connected via USB cable to a PC. You can use this camera to capture with the AstroDMx Capture program or etc. Also it complies with the standard UVC protocol and no need to install SVBONY driver.
