ZWO ASI120MC Color Astronomy Camera

ZWO ASI120MC Color Astronomy Camera
Item # ZWO-ASI120MC
  • Wow, a color USB 2.0 CMOS camera that does it all, for way less than you might think!
  • The ZWO ADI120MC Color Astronomy Camera can do planetary and lunar imaging, solar imaging, deep-sky imaging, and act as an all-sky camera with the included 150º wide angle lens adapter!
  • The 1.2MP CMOS sensor on this ZWO camera has an array of 1280 x 960, 3.5um pixels. Peak Quantum Efficiency (QE) is 75%, with no fixed pattern noise.
  • Shoot up to 215 fps at reduced resolution or up to 35 fps at full resolution.
  • The all-aluminum ZWO ASI body has a ST4 autoguider port and comes with a clear window.
  • Package includes USB & Autoguider cables, 1.25" nosepiece, CD with software, drivers, and instruction manual, and the 150º wide angle lens adapter.


When it comes to imaging, do you want to do a little bit of everything? The ZWO ASI120MC Color USB 2.0 CMOS Camera can image the moon & planets, it can image the sun with the proper filtration, it comes with a 150º lens adapter for "all sky camera" views, and the ASI120MC is sensitive enough to capture bright deep-sky objects! This camera from ZWO is truly a "do everything" camera, but at way less than the competition!

The ZWO ASI120MC camera uses a 1/3" CMOS AR0130CS sensor, with a pixel array of 1280 x 960 and a pixel size of 3.75 um. Peak QE is 75%, with no fixed pattern noise! An IR-cut window is included that will protect the sensor. A major bonus is the inclusion of a 150º wide angle lens adapter! When connected to the camera, you can do super wide angle shots similar to that produced by an all-sky camera. Capture images of the Milky Way stretched overhead, or record the look of the night sky you experienced on a special vacation. With the ZWO Astronomy Camera, you can do it all!

One of the major features of the ZWO ASI120MC camera is its ability to deliver up to 215 frames per second at reduced resolution, or up to 35 fps at full resolution. The wide range of capture resolution settings available with this camera allows you to go from planetary imaging to deep-sky quickly and easily, without the need for another camera.

The beautiful red housing of the ASI120MC is made of aluminum, and sports a USB and ST4-type auto guider port. 6.5-foot cables for both are included in the box. The 2" interface has M42X0.75 internal threads. A standard M42 to 1.25" nosepiece rounds out the package. The underside of the camera has one 1/4-20 thread in its center, and four M4 threads evenly spaced around the outside edge.

This camera comes with a 2m long USB cable, a 2m long ST4 guider cable, 1.25" IR-cut window, 150º wide angle lens adapter, Driver & Software CD, and a M42-1.25" nosepiece. Software on the CD includes the users manual, Windows camera driver, ASCOM Driver, SharpCap Image Capturing Software, FireCapture Image Capturing software, and Stakkert 2 Stacking Software.

Best video camera I've ever purchased
I bought my 1st one of these last year and liked it so much I bought a 2nd one.
This is by far the best planetary video camera I've purchased (this is the 4th
different video camera I've tried). I'm using Handy AVI for the software and its
easy to adjust the settings and I never lose the signal as I've had that problem
with several similar cameras. I especially like the fish eye that comes with it.
Great camera for the moon also. Forget the other ones, this is the best on the

Very good value and product
I purchased this camera so I could get better Solar System images than I was able to achieve with a NexImage 5. I live in Ohio, and seeing and transparency are often poor. This camera has given me excellent results.

These are the best of the images, and a variety of images.

Mars, Saturn, Lunar, Full disc Sun (mosaic), a solar close up, and solar prominences.

The planetary images with my CPC 800, and the Solar images with a Lunt 80 PT BF1200.

I am very satisfied.

Graet Camera
Great Camera, it worked straight out of the box.
On second use I was able to do some great imaging of sun using a Meade Solar Max 60 with the camera at prime focus.

A device for accomplishing goals.
I’ve added this device to my equipment, the goal was to achieve good planetary images, find here the first light of the camera aiming Mars, objective accomplished? look at the photo and judge it yourselves, details: 6oo frames with newtonian 8 inches F6 SW, 3x barlow, Neq6 SW mount and ZWO ASI 120mc camera in prime focus, from urban sky. Acquisition: Sharpcap, stacking: Autostakkert plus wavelets.
I haven't tested the product as a guide cam nor as an all-sky camera yet.

Questions & Answers

Product Questions

On which windows laptop will it work?
Can this camera be hooked up directly to a DVR w/o the use of a computer and if not, do you have any cameras that would work that way?
Hi. Does this package include the 150 degree all sky camera? Your description says all sky adapter....Dino 
Can the images from this camera be posted easily to Facebook or shared in an email?
I have two questions:

(1) Can the 150 degree All sky Camera be used at a Schmidt Casegrain prime focus?
(2) Can the color camera and autoguiderbe used together simultaneously?
Will I need any computer programs to interface this through?
Is the camera drivers compatible with Windows 10?
How do you compare the color version wzo asi 120MC and the black & white version wzo asi 120MM for guiding ? What should I expect in terms of guiding star magnitude with a 8 " SCT using a Lumicon OFF-axis guider with one of those cameras?

Thank you

Will this camera work with Windows 10 64 bit operating system?
I have an old LX90 Meade Telescope what other accesories or adapters I need to purchase to use this CCD camera with my telescope?
I ordered this camera and got a few days ago. According to the description of this item, the 1.25" IR-cut filter should be included, but I can not find this. Can you check whether the 1.25" IR-cut is included, or whether this is already built-in?
Are Linux drivers available for the ZWO camera line?
Does this work on Mac OS X?
What are the system requirements for the ZWO ASI120MC Color Astronomy Camera?
Hello, is it possible to hook this up to an ipad?
I love this camera and I'm considering it seriously. Alot of great comments about it online groups/blogs, but in your best opinion if you had to put it up against another ccd camera of equal, similar spec, quality and sensor what would the camera(s) be ?
Has anyone had success using this camera driven by a tablet with USB 3.0 via a microUSB-USB OTG cable?
Is the minimum exposure really 64 seconds?
What RAM and drive space are required to operate the camera & software (both capture and analysis)?
I read where there might be some compatibility troubles plugging this USB2 camera into a USB3 port (even though USB3 is supposed to be backward compatible). Is this still an issue or has ZWO overcome the problem?
is this a color or monochrome astronomy camera?
Can this all sky cam be used on a table, without a telescope? As in viewing meteor showers? Milky way, etc, etc??
