ZWO ASI120MM-S - super speed Mono Camera with high sensitivity

With up to 60 fps at maximum resolution, it is especially suitable for imaging moon and planets, but it can also be used for deep-sky.

Lower resolutions result in significantly higher frame rates, appropriate for "lucky imaging". VGA (640x480 pixels) offers 133 fps, the maximum rate of 254 fps can be achieved at 320x240 pixels.

With its high sensitivity and frame rate, the ASI120MM-S is very well suitable as autoguider which is connected via a stardard ST guider port.

Oberving nebulae and galaxies:

With the free "FireCapture" software from the internet, individual control of the camera is possible. Within seconds, even faint objects can be shown on the computer display.

♦ Automatic stacking

♦ Longer exposure times and higher gain

Great feature: a sharp 2.1 mm objective is included

The 150° wide angle lens permits the camera to be used fot meteor capturing and also for observation of the observatory or taking nice time-lapses.

For this application, you can mount the camera on a tripod or ball-head by using the 1/4" photo thread at the back side.

Software and drivers:

The Software can be loaded on the internet. Under "Astronomy", you can find the well-known free camera control and capture softwares FireCapture and SharpCap, but also other software for this purpose.

System requirements:

USB 3.0 must be available and supported by the operating system. Support exists since

♦ Windows 8

♦ Mac OS X 10.8

♦ Linux Kernel 2.6.31

The camera manufacturer writes:

"most important is USB3.0 host controller

we recommend "Intel® USB 3.0 eXtensible Host Controller"

from customer´s feedback, all intel host controller works and can provide the maximum data transfer
