Pre-Observing Procedures
This procedure is only for when the telescope has been used regularily and was not left in lightning shutdown. If things are obviously a miss (I.E. the power to everything is off) it would be good to perform the Startup Procedure.
Before actually performing any steps to get the telescope ready for observing you must check a few things and note any anomalies in the trouble report. These include:
Outside
Is the dome open at all?
During cold weather, is there ice or snow drifts on the back of the shutter or around the lower shutters limit switches?
During cold weather, is there snow above the entry way that would interfere with the domes rotation?
Is the dome positioned at a strange angle? (I.E. not South or directly over the entryway door).
Inside
Look at optical tape for signs of insect residue and condensation.
Look at drive and idler bearings for signs of the insect residue.
If humidity is high, examine primary mirror to see if it is fogged over.
Verify E-stops for telescope are not engaged.
Verify E-stops for dome (controller and shutter) are not engaged.
-
Check connections to TIM unit (check for snug connection for power and rotator).
If the answer to any of these questions is *YES* then there may be a problem and it should be noted in the trouble report.
