Telescopes - historical development, scientific importance, technological advances and the people behind this breakneck progress.

ASI120 is a very fast and sensitive USB2.0 camera. Up to 30FPS under 1280X960 full resolution! With a peak QE of 75%, beyond ICX618 and with no FPN(Fixed pattern Noise)! Long time exposure supported up to 1000s.

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

ZWO ASI224MC USB 3.0 color camera, (1/3″ and 1.2M pixels sensor, IMX224 with SONY Exmor and NIR Technology, extremely low read noise (0.75e – 1.5 e) and high sensitivity especially in IR range)

ASI224MC has a 1/3″ and 1.2M pixels sensor IMX224 with SONY Exmor and NIR Technology.
Extremely low read noise (1.5 e) and high sensitivity especially in IR range.

Very suitable for astronomy planetary and small DSO imaging

Astrophotography Performance

ASI290MM offers very good performance for astrophotography. Low read noise, high dynamic range, QE peak about 80%, AR protective window and much more.

High QE

Relative QE Curve, we estimate the Peak Value is about 80%.

USB 3.0 Port & ST4 Port

USB 3.0 Port: can provide 5Gb bandwidth to let ASI290 run at 82.2fps (12bit, normal mode) or 170 fps (10bit, high speed mode)  at full resolution(2.1Mega).

ST4 Port: can be used connect with auto guide port of mount, for guiding.
