If you think of it try turning off the guide corrections in PHD and recording about 20 minutes of unguided tracking. That would give you over two worm cycles of raw PE to examine. The uncorrected PE would show any major mechanical bumps much better than the guiding runs do.

Hmmm, how to turn off guide corrections?

Here you go - click the brain icon to get to this - also, you might want to increase the search region in pixels to a large number so the star doesn't drift out while you record...

The problem is mostly solved. Those oscillations are still here, but the images are fine now.
To connect the ED80 I use a photo screw, not the telescope rings... As a result connection between the telescope and the mount in a single point and there are vibrations that are mostly in the RA direction because I'm testing my mount on 0 deg DEC.

I will still continue to work on those oscillations and bring out the conclusions.

During the testings, some images came out like M101.
