Hi Paul

Thanks! I was experimenting with various settings in PHDGuiding and I had the guide star exposure set for 2 seconds, so I much have been following the seeing!

Imaging system: Mewlon 180 F12 at PF of 2160mm with ST7 at 0.86 acrsec/pixel.
Guide system: WO 66mm Petzval with (original) Orion Deep Space Star Shooter.

IIRC, I had PHD apply only 75% of the correction and I increased the Hysteresis (it “learns” from previous corrections) from 10 to 20.

Cheers

Dennis
