• If you leave the control room: Deactivate the TRACK mode in the Halpha Full Disc widget (poswatch) and set the mode to PC in the Manual remote control.

• If you notice the telescope is uncontrollably moving (away the PC guider window), the safest thing is to turn off the motor power supply.

• Value for the Ca line core: 3968.550 mÅ

• If you want to add new host in the CSSH widget: click “Hosts”, then “Add host”, then enter root@nameofmachine.

• Check that the exposure time for the cameras is less than 10-12 ms.

• When camera computers are rebooted you should send a command for them to start:

  invoke-rc.d dot-ccd restart

• Check the focus program: Change the exposure time for the focus camera by using +/- (in the keyboard) while placed on the focus camera display, until the RMS value in the middle box is close to 1.00. Moreover, make sure the telescope is in focus by moving steps +/- until the RMS values for the two rendered images are equal.
