Hi
I'm using fra400 on avx mount
533mc pro for imaging
220 mini for guiding via ZWO off axis guider
Asiair plus
My guiding is quite fine I'm between 0.30 and 0.60 RMS
I'm on fixed pole
Mount and scope perfectly balanced
Polar align perfectly done
Sometimes, one of the curves is going upside down and I'm guiding is going around 0.95 before going down to 0.4-0.5 RMS
I have easily 11 stars on multi star guiding
The gain for 220 mini is between 300 and 350, there is no saturation on the screen
The calibration is good
The guide exposure is around 1-2 seconds
The aggressivity guide is 70% on Ra and 50% on Dec.
When I have to reduce the aggressivity?
Why one of the curves is going upside down ?
Any ideas ?
Thank you in advance for your help and time
