Lilo Nice set of data. I have the same concern that there is something wrong with the internal level sensor on my Seestar as well. I don't get anywhere near the frame acceptance rates other folks report for 30sec sub frames. I am struggling to understand why I am typically in the 60% or lower range and never higher. As a seasoned astro-imager I know that I am doing everything on my end that can be done for the best possible polar alignment including trying different wedges, mounts, locations, nights, targets, etc. But nothing seems to make a difference including imaging night after night, at a Bortle 2 site, and trying targets at different altitudes and azimuths over the sky. I know that Seeing, high clouds, wind, etc all add to the variability but these cannot explain the complete inability to get higher acceptance rates at least some of the time. I have re-trained the internal level sensor multiple times and with multiple surfaces I confirm to be level with a level sensor to see if there is any difference, but nothing helps.
Here is the best indication that I know of that the level sensor is off. Since the Seestar requires a wedge to mount in the opposite direction as would be for a regular telescope. the angle reading on the wedge should be the compliment of the local latitude (90 - local latitude). At my latitude of 37.7degrees I would set the wedge angle to 37.7 degrees for a normal telescope and then fine tune it during the polar alignment. With the Seestar , since the wedge is pointed backwards relative to north, I would have to set the wedge angle to 52.3 degrees (90 - 37.7) and then refine it during polar alignment while the Seestar app gives me guidance. When the Seesstar confirms I am within 0.2 degrees on the altitude the wedge angle reading should be close to 52.3 degrees. Well, every time the Seestar app tells me I am within 0.2 degrees on the altitude, the Williams Optics Wedge (and my SW wedge) tell me the angle is 43 degrees. I checked this will an inclinometer which reads 45 degrees, so 2 degrees off but not 7 degrees off. This tells me that the internal level sensor is either not being calibrated correctly or is wrong. I don't know how to trouble shoot this any further to pin it down.
