Guiding Performance
Reasons for poor Dec guiding :
Failed Runs (5,8, 14)   - Failed Guide runs due to PHD2 Network Stream Reading issue (now fixed)
Black points (13)   - Cloud developing at end of Frame 1
Red Point (3)   - Wrong side of zero line (v. close to Meridian), need to Keep Principal  DecMode South for longer (Az 182)
Orange Points (11, 12)   - Non-effective Dec Guiding (South),  Fairly high Alt on East Side)
