ZWO ASI 120 Monochrome CMOS Telescope Camera - DISCONTINUED

The ASI120MM Uncooled Monochrome USB 2.0 CCD Camera by ZWO can image the moon and planets, it can image the sun with the proper filtration, it comes with a 150-degree lens for "all-sky camera" views, and the ASI120MM 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 ASI120MM camera uses a 1/3-inch CMOS MT9M034 sensor, with a pixel array of 1280 x 960 and a pixel size of 3.75 nanometer. Peak QE is 75-percent, with no fixed pattern noise! A clear window is included that will protect the sensor. A major bonus is the inclusion of a 150-degree wide-angle lens attachment! 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 ASI120MM camera is its ability to deliver up to 215 frames per second at reduced resolution, or up to 35fps 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 ASI120MM 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 inch interface has M42X0.75 internal threads. The underside of the camera has one 1/4-20 thread in its center, and four M4 threads evenly spaced around the outside edge.

A standard nosepiece (M42 to 1.25-inch) rounds out the package.

    Ask a Question
    • Will this work on a Mac OS X system?

      Yes, the can be used with a MAC.

    • Are there any reducers other than the TAK ones that work with this scope? Maybe something less expensive?

      Unfortunately, no, unless you want to take a big hit to the image quality at the edge of the field. The Takahashi reducer was optimized to the exact lens parameters of the FSQ-106ED-XIII, and other third party reducers will add aberrations and may requir

    • does this come with a tripod?

      Yes the used Celestron CGEM mount comes with a tripod.

    • 1. Adapter for C-mount camera lens? 2. Will it be able to focus replacing the eyepiece in a Stellarvue F80 finder?

      1. The camera includes a T-C adapter with a CS mount fisheye lens. Unscrew the fisheye lens and you can add any CS (not C) lens to the camera. To use a C mount lens, you would need to add a 5mm C-CS spacer to get from 12.5mm backfocus to 17.5mm.

    • Will its software work with Windows 10?

      The manufacturer states their software will work with Windows 10.

    • I would like to take pictures with a Meade LXD 75 5" refractor of the eclipse this summer. How is this camera for this?

      If you have a solar filter, this will work for the eclipse, but it will not cover the full solar disk at 1200mm focal length. You could shoot a mosaic, but that may not work near totality. A camera with a larger sensor like the ASI1600 or ASI071 would b

    • What do I need to connect this camera to a newtonian without any focus issues? I have 40 mm of back focus travel.

      You will not have an issue with this camera, as it has a native backfocus of ~15mm and the flange on the 1.25" nosepiece adds ~3mm more for a total of ~18mm used. It may be tricky to attach a filter wheel with this configuration, but we might have an opt

    • This camera has an autoguider port with ST-4 guider cable for direct connection to the mount. The specs say no integrated autoguider. Does this mean I will need autoguider software on laptop with the program reading the camera and sending control via the

      The ZWO 120mm does include an ST4 guide port and will work as an Autoguider when plugged into a PC

    • Can this camera take solar images, planets & deep space objects such as other galaxies?  Thank You...

      This camera has small pixels and high quantum efficiency, making it very good for high speed solar, lunar, and planetary images. For fainter deep sky images, I would recommend either using it on a smaller, faster telescope below ~1000mm focal length or bi
