My mount doesn't have PEC, but I would like to measure its PE.
What I am thinking is to point the mount at the meridian and dec=0 and shoot an unguided image for a few worm cycles. My expectation is that the PE will show up as oscillations in star images.
Does that sound reasonable?
From there, I would like to be more quantitative. By recording the above in Phd2, in Guiding Assistant Mode, I should be able to see the PE in the Phd2 graph. Right?
From there I can open the data in PhdLogViewer and see what is, essentially, an FFT of the PE. RIght?
Any tips or thought? Any other programs that would be good to use?
