The setting circles on a mount the size of the CG-4/EQ-3 are practically useless. Setting circles are not a reliable method to find faint DSOs, especially with an f/10 Schmidt Cassegrain.

If you still need them aligned, setting circles are meant to be rotated to align them. But it really requires practice and I have never even tried to use setting circles before. Even on my mount, which costs what you payed for your whole telescope, the setting circles do not have the accuracy to pinpoint objects with ease. It's faster just to star hop.
