A versatile camera has just become faster! Featuring a USB 3.0 connection, image download times are lightning fast.  The ZWO ASI120 Super Speed Color camera is a perfect choice for lunar and planetary imaging and features a CMOS sensor sensitive enough to capture bright deep-sky objects.  Truly a "do it all" camera at an incredible price making it the clear choice for the serious beginning or intermediate astrophotographer.

The ASI120MC-S is built on a 1/3" CMOS AR0130S full color sensor.  Capable of producing single shot images in full color without the need for color filters.  The pixel array of 1280x960 and a pixel size of 3.75 micron square, this camera is capable of capturing moderately wide fields with the included 150º wide angle lens adapter.  Peak QE is 75% with absolutely no fixed pattern noise.  Protecting the sensor is an IR-cut window.

An ultra fast incarnation of it's predecessor, the ZWO ASI120S has the ability to deliver frames at 254 per second with reduced resolution or 60 frames per second at full resolution.  This wide range of resolution and capture settings allows you to switch from planetary and lunar imaging to DSO's easily without having to weigh down your set up with an additional camera.

Housed in a gorgeous metallic red aluminum housing with both a USB and ST4 autoguider port.  6.5 ft. cables for both are included as are a  2" M42x0.75 threaded interface and standard M42 to 1.25" nosepiece.  A 1/4-20 thread in the center bottom of the camera makes for easy attachment to a wide variety of camera mounts and tripods.   4 M4 threads offer additional mounting positions, along the outside edge.

This camera will include a 2m long USB 3.0 cable, a 2m long ST4 guider cable, 1.25" IR-cut window, 150º wide angle lens adapter, driver & software CD, and an M42-1.25" nosepiece.  Software on the CD includes a user manual, Windows camera driver, ASCOM driver, SharpCap image capture software, FireCapture image capture software and Stakkert 2 stacking software for post processing.
