Guiding Performance
Reasons for poor Dec guiding :
Black/Purple points (none)  
Red point (9) - Non-effective Dec Guiding (South), large Dec spike with guide corrections move guide star to wrong side of zero line.
Red point (10) - Non-effective Dec Guiding (South)
Orange targets () - Two points with poorly effective Dec Guiding (South), some dec spikes / overcorrection.
