Thanks Ken and Barry,
I appreciate the work you guys are doing on this. If it's ok with you Ken, I'm going to copy this post and send it to Ivan at 10 Micron. He has been very helpful and it may give them some additional information, along with the SGP log. The fact of the slew registering "false" during the telescope centering routine should help narrow the list of suspects. The snippet you have show is the time when the mount freezes in tracking. It appears to be occuring during to conversion from J2000 to JNOW coordinates. Your eye balls must be crossed looking at all of this stuff. I have changed Per's ascom driver to Jnow, but that has not helped.
Probably a dumb question, but here goes: is it possible to avoid the coordinate conversion and see what happens?
Thanks again for the help Ken and Barry.................Jerald
