iOptron CEM70

I know posting PHD2 guiding graphs is really boring but tonight is first light for a new iOptron CEM70 mount from Sidereal. This is guiding is from a 10" Newtonian with an off axis guider riding on the mount. As good as the EQ6R-Pro is, I've never had guiding like this.

Good one - mine was doing about 1.5" - 2.5" total RMS over the last few nights, so you got a good one...

I typically get 0.7" to 0.5" out of mine on nights of good seeing.

So my CEM70 had a bit of an issue with it's RA axis, that was resolved by Diego - Now I'm seeing guiding from around 0.6 to 0.8 Seeing is just average tonight I think.
