Product Details

  • The ZWO ASI1600MM Pro Cooled Monochrome CMOS Camera is a high-performing astrophotography camera for deep space astrophotography or lunar/planetary/solar imaging,

    Deep Space Imaging with the ZWO ASI1600MM Pro

    As a deep space camera, the ZWO ASI1600MM cooled version can reach temperatures 45 degrees centigrade below the ambient temperature which brings the thermal noise buildup down to a minimum. You can take pictures of up to 33 minutes with this camera, but with a read noise of 1.2 to 3.8 electrons (depending on gain settings), exposures that long is rarely necessary.

    When shooting deep space images at full resolution this camera pairs very well with telescopes with focal lengths between 300 mm to 1,000 mm, and when it's binned to 2 x 2, it pairs well with telescopes 1,000 mm to 2,000 mm in focal length.

    Planetary Imaging with the ZWO ASI1600MM Pro

    As a planetary camera, the ASI1600MM Pro is versatile. For solar imaging, this camera can record full 16 mp videos at 23 frames per second and capture the entire sun with a 1350 mm focal length! If you are looking to speed shoot planets like Jupiter and Saturn, the ASI1600MM shoots at 192.4 frames per second at 320 x 240 resolution!

    ZWO ASI 1600 Pro Cooled Color CMOS Telescope Camera Features

    Camera Sensor

    Panasonic MN34230 Sensor

    The Panasonic MN34230

    At the heart of the ZWO ASI1600MM Pro is the Panasonic MN34230 CMOS Sensor which is known for its exceptional light-gathering efficiency, low read noise, and high resolution. The sensor will record up to 16-megapixel images on a Micro Four Thirds format. The peak quantum efficiently of this CMOS detector is approximately at 60% and it has a dynamic range between 9 to 12 stops (depending on gain settings). In other words, this sensor is the same size as an 8300 sensor, has twice the megapixels and is 30& more efficient in light gathering!

    • Diagonal 22.2 mm.
    • 16 Megapixel (4656 x 3520).
    • Very low read noise: 1.8 electrons at 150 DB gain & 3.8 electrons the lowest gain setting.
    • Electronic shutter: No vibration caused by a mechanical shutter.

    DDR Memory Buffer

    The ASI1600MM Pro camera includes a 256MB DDR3 memory buffer to help improve data transfer reliability. The use of this memory buffer minimizes amp-glow, which is caused by the slow USB 2.0 transfer speeds.

    ZWO ASI 1600 DDR Memory Buffer

    DDR memory buffer is the main difference between ASI “Cool” and “Pro” cameras.

    Astrophotography Performance

    ASI1600MM Pro offers low read noise, low dark current, high dynamic range. Its built-in 12-bit ADC provides 12 stops of dynamic range, which is better than KAF8300!

    USB Port &Hub

    ZWO ASI 1600 Ports &amp: Hub

    USB 3.0 Port: Provides 5 GB bandwidth to make it possible for ASI1600MM Pro to run at 14.7 fps (12-bit, normal mode) or 23 fps (10-bit, high-speed mode) at full resolution (16-megapixels).

    USB 2.0 HUB: Can connect with various accessories, including a filter wheel, guide camera or electronic focuser, allowing you to manage your cables better. There are two short 0.5 m USB 2.0 cables included with the ASI1600MM Pro. The hub is powered by the external power supply if you connect one.

      ZWO Makes Great Cameras

      Works great. Came early.

      Rapid failure of the cooling system

      After I received my camera I used it twice for solar astrophotography and it functioned well. However the third time zip used it I noticed that while the computer screen for the coolers operation said it was cooling fine at 100% power ,in fact the camera was heating up slowly. I went over the entire system, power, fan, computer control and all looked fine but no cooling. I contacted ZWO and they sent me to their faq site. The info there appeared to say I had a temp sensor failure. I have attempted to contact them again but two days later I have received no response. I await their help.

      The best astrophotography camera for the money, 'nuff said

      This was my first cooled camera when switching from the DSLR. I have been very impressed with it and am so happy with the results I have gotten with it. This is truly THE best mono cooled camera you can get in this price range.

      Why QSI683?

      Asi1600 give you same FOV same pixel size 3.6 nm and cost 3X chipper ...

      Behold! Cooled cmos and all its Glory!

      This is the best overall cooled cmos camera you can get for the money. I have no regrets in my purchase of this camera. Can you believe some modified dslrs charge more and don't even cool and also have less quantum efficiency? Don't let the micro 4/3 sensor disuade you. It's such an amazing camera which I plan to always keep. Tell em Kurt sent ya
