(* means a trouble report has been issued or appended to)
Observing Specialists: Bergeron
Remapped the NA2 guide camera due to guider work this afternoon. Opened at
17:40. Had some cirrus early, but cleared and was photometric with calm
winds, steady temps and mostly good seeing. DIS functioned nominally. The
autocollmate proceedure was turned off for the entire evening, meaning
temperature based focus updates would only occur when the telescope was slewed
or a focus change was made. This was done as a temporary work-around for the
observed secondary-induced image shifts during the autocollimate adjustments.
I didn't notice any large image shifts in the guider offset plots...will
look at the tcc log data when time permits.
                            OBSERVER COMMENTS
No problems.
