drift error fixed on RA

Above, the star trail is a straight line. The angle of deviation is close to 0, LX200 14" and STL11K

To do that you should turn the base of your mount to east. For me it was the case, may be for you it will be the inverse depending of your setup (CCD camera position...)
Repeat the step 5 and check the result, if the angle is larger than your first exposure, that mean you turned your mount in the wrong direction.
After several iterations you should have a picture like the one above. That mean your RA alignment if enough for the moment.
