I've been struggling to find the correct settings for my 290MM mini in PHD2. I've tried many different settings but haven't been too successful. I get the guide scope properly focused first with the provided zwo camera software. I can get an image but I have to drive the camera gain, in PHD2 advanced settings, down to almost 0, have the screen brightness almost full right, and have exposures at 1 sec or less. Is this similar to what others are getting with this camera? What are the ZWO recommended settings? I see most people recommend exposure settings of 2 - 4 secs so as not to get too many guide signals sent to the mount. Maybe the ASI290MM mini is too sensitive to have exposures that long even on the darkest night (doesn't seem right though).
