Well this is interesting. In the PHD2 Calibration info, you can see where PHD2 says that for RA it is expecting 12928.7 a-s/sec (or about 860x Sidereal) and 27073.9 a-s/sec for DEC (about 1800x Sidereal) but the actual measured rate is 3.335 a-s/sec and 7.851 a-s/sec (or about 22% and 52% of Sidereal) for RA and DEC. In the Web UI for StarGO2 I have The guide rate set at 0.2 (20%) of Sidereal. So I'm not sure what that setting does, or how PHD2 is getting these numbers, or how I can change them. Anyone have any ideas?
