I just want to second George’s reply, as I too have a perfect balance on my G11T. Granted, it’s sporting a RASA 11 v1 at the moment, but I’ve seen (and have the screenshots!) total RMS as low as 0.12” without pec (still haven’t got that right) on good nights. Typical garbage guiding is around 0.3” up to 0.5” if guiding with thin clouds passing through.

I’ve actually seen PHD2 charts of over a minute without a single correction (0.5” exposures).?
Guide cam is a ASI178mm, 4x Bin (I refuse to lose stars).

I use PHD2’s PEC RA algo and started using Limit Switch for Dec after seeing a video by the legend himself, Brian V.

My trick is minimal maintenance. Must be the crushed exoskeletons smoothing out the tracking.
