The spikes I mention can be seen in this excerpt of a PHD2 log:
As you can see the error is most of the time in a band of +-1", but there are occasional spikes. Even without the occasional spikes, I do not like too much the performance, too much oscillations with just 9 lbs of equipment (Sharpstar 76EDPH with all the typical add-ons).? With the 343mm focal length of the 76EDPH? the resulting images are perfect, but? I would like to be able to image with longer instruments (with 1200mm fl as the maximum perhaps).?
I think that oscillations could be related to stiction and may benefit from a fine adjustment of the worm gear.
Best regards,
Daniel
