Dome HOME failure

Friday, December 13, 2019 6:17 AM

Problem(s) Encountered:

I used the software switch to send the dome home at the end of the night and rather than going home, it kept rotating to the right.  I finally stopped it, put it on the contact manually, closed, and reset the dome azimuth to 320.  It had somehow gotten far off (like 10s of degrees).  Didn't lose any observing time, but lost maybe 10 minutes of sleep!


There is a magnetic HOME switch that was no longer making sufficient contact as the dome passed by the HOME position.  Repositioned switch, tightened everything down, and all is well again.
