    Have you tried lowering tripod legs to get better PA ?

    Yes, I tried and it got better, but that's the results you're looking at... The polaris wasn't fully centered and I will try to get it more accurate next time but could it be another issue or is the polar alignment the key issue here?

  2. For quite a while I've had an issue where the images I take have trails that show up when going higher then about 20 seconds exposure time. I do a rough polar alignment where you can still see the polaris in the scope as I live in the north of Sweden and the EQ3-2 mount doesn't allow for accurate adjustment above 64 degrees.

    I'm 100% sure that the locatation, time zone and time is correct, I've also parked the scope to the position with the scope facing polaris and the weights downwards. I did a 3 star alignment and after a 1 min exposure with my Olympus 420 the result was as the first image I attached. For 20 second exposures I get the second image attached but once in a while without having touched the scope (yes I am 100% sure of this, I stood perfectly still a good distance away from the scope and triggered the shutter with a remote control) I get results such as the third image.

    My guess is that the cogwheels are slipping somehow but I'm gonna ask here to be sure.
