  1. 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?

  2. Hi,

    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?


  3. 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: https://i.imgur.com/JHMp01i.png

  4. 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,
