I tracked for about 15 minutes then adjusted the cr cal time, recald and got it to track for about 20 min.s with no problems. I used 0.5 sec for the cd (dec) cal time as it runs fast(on my scope) and 3 sec for the cr (RA) cal time which runs slow and I think I used 5 sec on the exposure time. I have the latest dec motor and upgraded the ROM chip last summer and since the speed seems relative smooth, consistent (when the OTA is balanced) and well matched in the higher slew speed settings I didnt do the upgrade with Blessings kit. The upgrade kit could do the equivalent of resetting the cd cal time by slowing down the gears. Another potential problem may be getting all this to work at f10 vs. f6.3 for shots where you want a narrower FOV. Stars will drift across the CCD faster and it may not be easy to set up, calibrate and getting tracking with enough response to stay guiding without losing the guide star. I will be trying multiple combinations with varying star brightn!

ess and see how it goes. Let me know how you do. Good luck.
