A year ago I had many nights with PS being off for very well known targets or failed entirely. PS2 and Astrometry. Didn’t matter which. Some solves failed while the object was in the center of the screen. Sometimes PS would place the object in the center, yet another object situated nearby couldn’t PS, failed.
What worked for me is doing a manual PS of 8sec/2xbin image, near the pole. Not exactly on it, I’m typically 88deg or so. I don’t have permanent setup, so I polar align and such, then park the scope to 90deg (then unpark), and then offset a bit before taking the image. I right click and choose solve, blind solve, the image taken from this position, it gives the thumbs up as 100 confident, and after that every slew/center on is good the rest of the night.
This is what works for me going on a year later now. I’m sure others will say not to use the pole area and its wrong as was the case in my other posts on this back when I had the problem. I just know this works for me. Solved the problems I was having with PS. Nothing else did.
Can’t hurt to try it. If you find an alternative solution by all means come back and let everyone know. Might be useful for someone else down the line.
