Re: DEC Crosstalk

Clayton Yendrey

Thanks for the excellent explanation of what happens.  That would explain, I believe, the appearance of large RA spikes literally out of nowhere.  It would seem that the bearing mount/assembly, besides lacking preload, could also be insufficiently rigid as a contributing factor?

This problem is more prevalent/larger magnitude when the mount pointing at high declinations.  It was around 3 hrs before meridian flip on the target (M51).  No spikes readily apparent when guiding at Dec 0/10 minutes west of meridian but began occurring immediately after slewing to target (M51).
