Product Details

  • The ZWO ASI1600MM Pro is a Micro Four Thirds camera packed with features that help you produce world-class astrophotography images.


    • Exceptional noise reduction technology and video capabilities.
    • The 1600 Pro is ideal for photographing: Nebulae, galaxies, planets, solar images, lunar images, and more.
    • Can run without external power in normal mode- without cooling or filter wheel in use.
    • USB 3.0 Port allows your camera to run at 14.7 fps at base through its 5 GB bandwidth.
    • USB 2.0 Hub provides attachment to various accessories for better cable management.



    The ZWO ASI1600 has a built-in 12-bit ADC but can provide over 12 stops of dynamic range! Which means it can capture a wider tonal range a KAF-8300 sensor. The Camera inherently has a much lower read noise, at a 0 gain setting and will further decrease the higher the gain.

    It also includes an upgraded PCB board with 256MB DDR3 memory buffer. Slow data transmission can cause amp-glow around your image, so the DDR memory buffer takes care of that for you.


    Most ZWO cooled cameras have a short back focus, making them very adaptable to almost any telescope system. The ZWO ASI 1600 has a back focus of 6.5 mm! Check the ZWO Pro Back Focus Chart for the best configurations.


    The ZWO ASI1600 is capable of pushing at a maximum of 40 to 45 degrees below the ambient temperature. The camera itself operates optimally within the temperature range of minus 5 degrees Celsius to minus 45 degrees Celsius and is best stored within the temperature range of minus 20 degrees Celsius to minus 60 degrees Celsius.

    This powerful cooling system complements the naturally low read noise of the camera to further refine the quality of images produced- aiding ZWO to continue to provide CCD quality at CMOS prices. And that's just one example of how each individual part of this top-notch astronomy camera comes together to produce a genuinely exemplary whole!


    The ZWO EFW7 can hold up to seven 1.25-inch mounted or 36 mm unmounted filters. The 36 mm filters are held in place with included set screws and washers.
    The EFW7 body is CNC machined from aircraft-grade aluminum and is black anodized. It is sturdy and reliable, yet weighs just 14 ounces and is 20 mm thick! Inside, an NPM stepper motor is used to rotate the carousel in any direction. The EFW7 is powered via USB and includes a cable that can be plugged into the USB 2.0 hub of ZWO cooled cameras.


    Switch between each filter to gather colorful variations of light resulting in different vivid images! Every ZWO 1600 Kit comes with a set of LRB filters and a complete set of 7-nanometer narrowband filters (Ha, Sii and Oiii). Finely polished down to an optical accuracy of one-fourth wave, the filters provide zero apparent optical distortion from the filters.

    Way better than high point

    High point sucks. You guys have way better customer service and reminded me I forgot to buy the power cord.

    Perfect service

    This was my first astrocamera purchase, on my first telescope. My research had me concerned about back focus and spacer selection. The guys at OPT had everything I needed selected and sitting on the counter waiting for me when I arrived. Then one of the service guys came out and walked me through the “how to” for installation. It was spot on, and I was imaging that same evening!

    Excellent Camera Outfit

    The instructions are excellent compared to others that I have experienced. The camera appears to work well. I’m still learning to use the CMOS versus my CCD camera.

    ASI 1600 Purchase

    I would have rated this purchase a 5, but I received the product with one cracked filter. I called customer service immediately and explained the problem. The customer service person asked that I send a picture of the filter via email. hey followed up e next day and said a new filter was already sent out. I received the new filter within 3 business days. I couldn't ask for better service.

    They work hard to make you happy.

    I bought a ZWO ASI1600 kit from them with the EFW, camera and filters. The EFW didn’t work for some reason; no computer would recognize it when you plugged it in to any USB hub. After a chat with OPT and a couple emails with their tech guy (and a ZWO tech guy as well), OPT has me return the EFW to them to take a look at (as their expense) and after seeing it was bad, they fired a new one back to me. Yeah, the whole exchange took a couple weeks but I can’t complain about their effort to fix it and the fact they replaced the bad one with no hassle. My only reason for a 4 instead of a 5 is that I had to contact them a couple times to get updates on the process when I felt like they should have kept me in the loop more; but that’s a minor personal complaint. I will continue to buy from OPT as I have done for many years now.
