I have not been completely happy with my goto star alignments with the CEM40. As usual I cannot prove it yet due to the September clouds rolling in but.....there are markings on the saddle which I haven't really paid to much attention with. With the mount c/w shaft pointed ahead of you, the saddle has two hex screws on the left hand side to push/pull the long portion of the saddle grip. I noticed that the bottom was at least one unit off from the upper one.
Being that the mount was shipped with the Vixen configuration, I had no reason to really check the alignment of the saddle, thinking it was done at the factory.
I think this is what's creating a "false" cone error and why the selected alignment star was consistently off. The manual really doesn't give any reason as to what would cause the alignment to be off. I don't know how the other CEM's have the saddle configured, but if it is the same as the CEM40's, I think this is where you should look to check that both ends are in alignment.
As you can see, they are both in alignment now.
Comments welcome, and I will report back on this as soon as I get clear skies again.
Hope this helps and if you find yours is out as well, please let me know.
