    Hi guys. What is the difference between v1, v2 and v3 internally?

    Hi, I’m just about to get the 1600MM Coled (V3), is there any issues i should look out for? Is it worth only using the USB3.0 to connect the camera to my computer and not use the cameras integrated usb2.0 hub at all?

      Hi Duncan
      I think you misunderstand USB HUB on camera. USB HUB is connecting to other accessories, the signal will through USB3.0 port transmit to computer. The hub can’t connect to computer.

    Hi Sam
    I have the V3, is it worth the upgrade to the Pro version if I work only with USB3? What is the main difference between the two? only the buffer?
    If I connect my guider to the Hub of the camera, would it create more amp glow?

    Thank you



    • Sean Wang

      Yes, 1600 V3 and Pro only have one difference- DDR buffer. If you need use a HUB, make sure you use a USB3.0 HUB.

    I’ve been using the version 2 and it’s a great camera. Has the version PRO a heating system for the front glass that covers the sensor? In my area temperatures rise below zero usually and I’ve had ice issues with the 1600 Version2. Thanks i advance,

    I have had the ASI1600MM-Cool for a few months now, and for the most part it is an amazing value for the price point. I do have one issue that drives me crazy about the camera though. It appears to suffer from microlens diffraction patterns on moderately bright to bright stars. It is thought this could be caused by a lack of AR coating on the sensor protective glass itself (not the optical window). Is this a known issue with the camera? Has this issue been fixed and I got an older v3 camera? Assuming the pro version uses the same panasonic sensor, I would imagine the issue would be exactly the same then. A good example of the issue can be seen here: http://i.imgur.com/JHMp01i.png

    I am considering ASI1600MC Pro or ASI294MC Pro for video observing (NRTV or EAA). I also plan to use the same camera for bright field imaging with a microscope. Can you advise which camera would be more suitable for my applications?

    So my ASI1600 Cool which I recently bought and have not even tried is the un-professional version with amp glow issues? Great! Any chance of an upgrade service?
