ASI120MM-S USB 3.0 monochrom Autoguider Camera (fish-eye objective included!)

Code: ASI120MM-S

ZWO ASI120MM USB 3.0 monochrom Autoguider Camera (MT9M034 Sensor, Pixel 3,75 micron) with Interface (fish-eye objective included!)

ASI120S is a super speed and sensitive USB 3.0 camera. Up to 60FPS under 1280X960 full resolution!

Very good cameras with extra high image quality. Extra high sensitivity and extra low readout noise resulting exeptionally good image quality, or high snr (signal to noise ratio).

Output is 12 bit (over the usual 8 bit), readout time is very fast. ROI is supported, so it can be use as a lower resolution camera for planetary imaging with very-very high transfer rate. While transfer rate is 35fps at full resolution of the USB 2.0 models, the new 3.0 version has amazing 60fps maximal frame rate! At lower resolution it is even faster, 133fps at 640x480. Extremely good!

Supported OS: Windows XP 32bit/64bit, vista, Windows 7 32bit/64bit, Windows 8 32bit/64bit
