This is what I get using an LX-90 on an X-wedge. I have a 290MM mini guide camera the F4 guide scope, ASIAir plus, and it's plugged in via a cable to the audiostar auxiliary port. No matter the settings for guide calibration 600ms to 4000ms or max RA and max DEC settings 250ms to 2500ms, and aggression rates 25% to 100% I get 2 RMS (good enough) guiding for 1 to 3 minites, then guiding that forms a triangle drifting southwest to directly east, to northwest, then it continues the triangle drift south of the guide star or drifts west then east of the guide star. I usually get 90 to 120 RMS total during the triangle drift or east and west drift over a 5 minute period. I've made sure the mount controller is set to sidereal rate and ruled out that being the issue. When i try to pull the logs under the report bug pull, the app gets stuck at compressing log data and freezes, it won't let me send the bug report. Not sure since my wifi is connected to the ASIAir with out internet thats causing it to not send the bug report. Is there a way to save the log report to the device? Here is my post about it on cloudy nights too. https://www.cloudynights.com/topic/820511-meade-lx-90-can-anyone-use-pulse-guiding-with-their-lx90/page-2
