I'm new here so sorry if this information is elsewhere but I couldn't find it. I was wondering if there was any information available for the cooled version of the 174MM. Prices, details, dates, etc. Thanks in advance.

Teleskop Express and maybe some other shops already lists them, but the real market entry should start by the end of the month. On ZWO Facebook it had been written in comments that the introduction prices will be lower ;)

There is discussion about random banding issue with this camera, what is it? Can anyone comment on this?

Every CMOS sensor has fixed pattern noise (vertical bands) that is fixed and can be removed by a dark frame (amp glow also) and some random noise in the form of horizontal bands. To remove that you can use software, like latest Autostakkert2. Also stacking more frames decreases the problem.
