Hi Chris,
As far as I can tell I am; but being 100% sure with my eyesight
on that target can be a problem.
You are correct with the sync function. Unfortunately SkyVoyager does not have a multi-star sync option ( at least for the Tak driver).
Another IIS user has also been very helpful in providing step by step advice and a number of suggestions and we think we may have nailed it down to:
1. Some critical point not in alignement ie, maybe not properly aligned on SCP in polar scope or some other hardware out.
2. Potential problem with slewing in software or mount.
Which also seems to agree with your recommendation as well.
Thanks for the advice and comments
I will be paying close attention to these in the next few nights to try and see where the problem is.
