= How to start up observatory (no embedded images) =

 * Check weather ([[http://www.mpe.mpg.de/~burwitz/cog.html|outside conditions]]) /!\ '''use common sense''' /!\ 

 * Log on to control PC via VNC '''skydome.mpe.mpg.de''' port '''5200'''  
 
 * 1st check if '''mount handpad''' program and '''focuser''' program are running
 and connected to mount and focuser respectively. 

  * This should usally be the case.

  * If not start the programs and try to connect.

 * If they are not started, and cannot connect, then start up windows internet explorer. 

 * Then Log on to '''ePower #1''' and check if focuser and mount are powered on '''ePower #1'''. 

 * Power up the '''focuser''' if necessary and check that the '''focuser''' control program is running and connected.

 * Power up '''mount''' if necessery:  

  * switch on power supply on '''ePower #1''' if not yet powered up. Normally it should be on.

  * then toggle mount switch both on '''ePower #1''' if not yet powered up. 

  * checked if '''Mount handpad''' control program connects properly.   

 * Power up imager/s on '''ePower #1''' if not yet powered up. Normally it should be off on starting up.


 * open dome

= How to start up GOWI =

 * cool imager to target temperature (-30C typically - cooler power < 80% at target temperature)
 * start dark and bias frame sequence
 * set focuser to expected setting for the night (if known)
 * [[HowTo/Skyflat|take skyflats]] until start of actual observations

----

= How to start up GOWI using chimera =

 * Turn camera on (using power control)
 * Launch chimera:
{{{
# fixes broken sbig library (required.. otherwise you will get camera not found or something like that!)
export LD_PRELOAD=/home/welterde/libwrap.so
# launch chimera (connects to camera and telescope mount)
chimera
}}}
 * Cool down camera (using different terminal
{{{
# -T <target temp>   -w waits for it to complete
chimera-cam -T -25 -w
}}}
 * Unpark telescope using remote hand controller (not possible via chimera yet)
 * Attach rtd view
{{{
export RTD_CAMERA=0
skycat -rtd 1 &
# then click Real-Time -> Attach camera
}}}
 * (optional) Load scheduler program and launch it
{{{
# creates new database (use --append if you want to append instead of overwrite)
chimera-sched -f programfile.sched --new
# start scheduler
chimera-sched --start
# stopping scheduler (just doing control-c on the previous command will not stop scheduler!)
chimera-sched --stop
}}}
