Suavi - they still were nice and flat, not going above 0.5" despite PHD2 warning me of potentially unreliable calibration. I checked and indeed it had only now moved 3 steps in Dec compared to previous 8 for calibration.
last night, I again watched the guide star in MaxIM 6 at 400% zoom with crosshairs on and did not see it move in 3 hours. Must have been a hot pixel
(and the SXP tracks so well it didn't notice
)
I paid $500 USD for MaxIM 6...I may as well take advantage of it
