how do you safely remove the polar alignment scope from a eq6-r mount?

Don't they unscrew from the RA housing?

I didn't see anything in the user manual about polar-scope removal. You should e-mail SkyWatcher tech support, and ask them for specific, detailed instructions.

 

You should also delete your other, redundant thread, so that any answers you get, will only be posted in this one. grin.gif

Look around the perimeter of the rear of the RA housing, there may be a small hole hiding a set screw.  If there is one, you'll need a small metric Allen wrench to loosen it.  Then you should be able to unscrew your polar scope.

 

If there isn't a set screw, your polar scope may be cross threaded or seized.  If that's the case, only force will work.

According to the Orion manual for the same scope it unscrews much like the HEQ5 does.  Try grabbing the scope eyepiece just past the focus wheel and rotate it counter clockwise.  it should come off.  like @macdonjh said if it wont unscrew then it may be bound and force may be required.

 

Here is a picture of the back of the polar scope.  the screws here are for alignment only, not to remove it.

This is what it looks like once removed.  Note the screw threads on the inner section.  This is where it screws to the mount:

Now that we have photos, it doesn't look like there are any set screws securing the polar alignment scope to the mount.  Just to be sure, I'd double check the area I outlined in red on the mount.

It simply unscrews.  It may be tight so you might have to carefully grip it with something, but I have not needed to do that with an EQ6-R to date.
