I sent it in and they fixed what was causing my issues before. So far it seems to be working correctly. I posted about this on CN. The temp probe was failing, the sensor was getting fogged and iced up, so far that hasn't happened again, but I have only tested in Oakland,CA and Joshua Tree. Neither of these locations are very cold or very humid. The data from Joshua tree is exceptionally smooth and I like the camera. I would just also like to be able to use it on my Mac with EKOS again.
I actually gave in with the ZWO ASI071 pro, as with two cameras I encountered ice on the sensor at -10 degree Celsius. It strikes me reading that both of you have experienced this issue.
with the not-pro version I also had the mentioned amp-glow problem on the Pi with USB 2.0, that was "fixed" with the buffer introduced with the "pro" version.
My issue was 2+ years ago. so I figured it had been dealt with. However, I frequently read people posing example pictures of the frosted grid asking what they're doing wrong.
I got the 1600MM replacement - I recently sold it and replaced that with a 1600 MM pro.
