I wonder if this will work?
With my old C8+ on a wedge, I adjust the mount properly to center it visually to Polaris. If I then pick a Southern Star (say Sirius in Feb), can I use the following to Polar Align to NCP.
Center the star Sirius with reticle eyepiece aligning crosshairs with Azimuth and Altitude directions. Let it track for some minutes then re-adjust the errors by adjusting out 1/2 the errors in the Altitude and Azimuth with the mounts base positioning adjustments.Actually move the base azimuth and elevation.
Then re-center Sirius with normal viewing adjustments and let it track for a while, then re-adjust the mount in alt-az again by 1/2 of the errors with the base mount.
In my mind, I think, with several iterations, it should then be bang on - assuming the motor is at the sidereal rotational rate.
Will this not work?
In mechanics, and electronics, this adjusting out 1/2 the error on multiple iterations is a valid method of accurate tracking.
Again, I think this would be easier than selecting a southern star, adjusting one direction, then picking an eastern star then adjusting the other direction, repeating, etc. My method would not require changing stars.
