Hi Jeremy,
This is probably my fault for giving you that impression, but the EQ6 is a very good mount but it does have limitations when it comes to guiding in DEC.
As you can see from the attached PHD graph that the EQ6 has difficulty reversing direction in DEC and more and more pulses are sent from PHD2 to get the EQ6 to overcome its backlash.
The workaround for this is to deliberately set the polar alignment so as the stars always drift in one direction (e.g North) and this way the DEC guide pulses are always in a Southerly direction and it has no reason to reverse direction.
Given all of that this graph is not bad with a total RMS of 0.77 arcsecs.
Cheers
Bill
