Is that right? >> >> Steph We have not unusual problems with homing. For the primary I homing without anything problems. For the secondary I repeated twice 'Home axes A, B and C' i.e. at first time the errors was more than 200&400 microsteps . Some additional thinks: a night before the temperature was -8 C. At the last nigth tenperature was approximately 4C +/- 0.5 C. I any case tonight I will repeat the home&relax mirrors. ----- About pointing models: corresponded last ours observations I found nest solutions for the MARVELS observations: After 'gotoField' on new plate it need add 'tcc offset arc 0.0, 0.002, 0.0). In the most cases that is enough for the find guider stars. The value 'delta Dec' may be between 0.002 and 0.004. I have not explanations, that is only result of the observations at last night.
