Sunday night I thought I would attempt to train the drive for periodic error correction or PEC. It took longer than usual to get the drive aligned tonight. I suspect because I dumbly sync-ed Polaris after each drive Azimuth/Altitude(tilt) adjustment. It was unusually humid and transparency was mediocre. As one might expect clouds moved in ending the night.
It dawned on me that I should simply clear any PEC data that might be polluting the drive and causing it to correct for non-existent errors. Tonight I bring the scope upstairs and retrain the RA/DEC axes. This is different from PEC training. If I get a break on the sky I'll try imaging one easy DSO. There are few visible from my tree obstructed terrace between 9-12 midnight. This weather is really sucking right now.
