The major long waves on my guide chart above were 100% caused by a mechanical problem that I caused. The guide motors are interchangeable, so stupid me I assumed the worms were as well. Wrong!. Tech support caught is and all that is gone now. Still a rough looking graph , but seeing has been so hazy that by 10 pm the only lights visible in the sky are Jupiter and Sirius. Best SNR I can manage right now is 4-5, so I don't think I'll have useful guiding or imaging until I have decent seeing. When a hole in the haze passes by it seems to guide under 2"rms, but only briefly before seeing closes out again. Obviously no fine tuning possible. With my mount, 1x is the only choice that gives a useful result. I think the start with .5x and work your way around to your best result strategy is wise for other mounts, however. I'm finding if I adjust the exposure length to the longest which will hold the star, then let it settle. I then make cautious adjustments from there, waiting a few minutes and then evaluating the graph, that this approach works pretty well. I believe only one correction per exposure can be made. If the speed is too low, the trace may run away and back because of under correction, if too fast it may be choppy from excess corrections. I'm just learning.
