Yeh, I wasn't sure what words to use, or how to easily explain it.
Take the DEC axis. When I got the mount, if I turned the dovetail holder so the arrow lined up with the Zero on the Dec Scale ring, the scope was "lined up" with the axis and truely pointed straight ahead. So when I lined up on the SCP, all was good. Now that I have pulled the mount apart, I need to make sure that the scope is pointing to zero dec when the Scale ring is showing zero. Otherwise, when I am trying to align to the SCP, the DEC axis may be pointing a little to the left or right of the SCP (when viewed from the eyepiece of my refractor).
The same with the RA axis. When I first set up, the counterweight bar should hang straight down, (ignoring the fact that it points forward as a result of being 28 deg south) directly under and centred on the in-build polar alignment scope. When viewed from the front, the bar points straight down to the ground. Other than standing back a distance and adjusting by eye, how do you make sure that the RA axis isn't ever so slightly rotated a bit.
I figure that a slight misalignment in both, or either axis (axes), will make guiding a bit more difficult. Or am I worrying about nothing?
Thanks
