Roy- Talked to Kirk and told him what you had written. You were

exactly right- he had the backlash correction set to 5 from before the

declination upgrade and forgot to reset it when the mount came back.

He was able to switch the setting down to a 1/2 (money well spent with

the upgrade) for manual adjustments and the movement was perfectly

smooth in both N/S directions. He also tweaked his polar alignment

even tighter so that it's now 20 minutes with no apparent RA/DEC

drift. He plans to set backlash to zero when using the STV. He

couldn't believe he had forgotten to check something so obvious- and

very thankful that there will be no more nights of hand-guiding for

hours in 18 degree weather! Thanks for your help!
