Pointing Limits |
Zenith distance less than 75-degrees to avoid tipping mirror. |
Wind Limits |
No explicit limits, but when leaves and twigs start blowing in perhaps
you're pressing too hard. Usually, before this happens, the tube will shake too much for reliable
observations anyway. |
Humidity |
Close the dome at 95% or earlier if necessary to exclude any
and all moisture from the dome. In particular be alert for sudden and unexpected fog formation and
do not leave the vicinity of the open dome without being very alert for any sudden
change in the weather. If you can see moisture in your flashlight beam, or if surfaces get wet:
close! |
Ash |
Consult 3-meter operator (8-0652). |
