To All,
Glad to help where I can
Get used to the Dec and Ra spikes whilst guiding, some nights in Sydney I’m almost flat lining at 0.45 arc sec total and other nights ( high humidity/ bad seeing ) it’s see sawing at 0.85 + arc sec total. You can’t guide your way out of bad atmospheric conditions. The night sky is a moving target when it comes to atmospheric stability ( unless you live in a desert )
Consistent poor guiding is generally caused by mount mechanical problems or bad atmospheric seeing or a combination of both
Medium to Big periodic spikes generally can be caused by periodic error in mount worm gear , wind gusts , cable drag or snag and atmospheric conditions
I recommend you join the PHD2 forum for future support and help
If and when you have serious issues you can post your guide logs and Bruce and Brian can evaluate your issues with a timely reply and recommendation.
Cheers
Martin
