Hi Matt

Never seen an EQ6 PAS, but if the mount’s assembly and operating instructions are similar to the Vixen mounts, then the PAS should already be "accurately aligned" at the factory.

So, are you saying you need to align the reticule rather than the actual PAS body in the RA axis?

I once (unintentionally) took my reticule out when re-greasing the mount, thus screwing up the reticule position, hence alignment. All I had to do was re-align the reticule by sighting on a fixed terrestrial object (a pole 2 km away) such that the pole was centred with the OTA on the left. Then, I rotated the RA axis 180 degrees to place the OTA on the right to check that the (terrestrial) pole was slap bang in the middle of the PAS.

It wasn’t, so I had to adjust three very small grub screws that moved the reticule (not the PAS) until after a couple of iterations, the wooden pole always returned to the same spot in the reticule. These are tiny grub screws with an Allen key head, and only required a small tweak to cause the reticule to move a reasonable distance.

If the EQ6 is like the GPDX, be careful as there is a real danger of stripping threads or mashing the socket where the Allen key fits/locates the grub screw.

Cheers

Dennis
