I closed the mirror covers at 23:45 due to the outside dust rising ovewr
5000cts and the inside approaching 3000cts.  I closed the building shortly
afterwards as the dust slowly climbed higher outside.
We re-opened at 03:45.  Dust started climbing again about 30 mins later
but the inside dust counts were still manageble. My observer finished at
05:33.
No telescope problems tonight.
