Hi John
Nice graph and excellent M8! At long focal lengths (1500mm and above) I made significant inroads into guide corrections when I adjusted my guide correction rate down, from the default of 0.9x Sidereal to 0.5x Sidereal.
So, when an RA correction is required there is less tendency to over shoot then reverse the overshoot and so on, leading to a yo-yo situation.
Cheers
Dennis
PS – what mount do you have?
