      * port: 7600
      * driver: Apogee CCD
      * Dual CCD: Main

    - select the ''Apogee CCD'' tab
    - verify the following settings:
      * in the port section ''network'' is selected
      * in the network section:
          * subnet: 10.0.255.255
          * **Note the 4K guider is currently being repaired . We are using the VATTspec guider for all guiding. In practice this means the ip:port will be 10.0.3.12:2571**
          * <del>offset guider (used with imagers) ip:port : 10.0.3.14:2571; slit plate guider (used with VATTspec): 10.0.3.12:2571</del>

    - click the ''connect'' button in the ''Connection'' field
      * (after a few seconds, a bunch of new fields and tabs should appear)  
      * (The message "[ERROR] Model is not supported by the INDI Apogee driver" may mean that the camera is not powered up.)
    - near the bottom of the window, turn on the cooler
    - IF YOU ARE GOING TO BE AUTOGUIDING:
      * click on the "INDI-VATT-GUIDE" TAB
      * click "Connect"
      * (a UT clock should appear and begin incrementing.)
    - exit the ''INDI options'' window
    - click OK in the ''INDI Configuration'' window
    - click ''Connect'' in the ''Connect Equipment'' window, in the camera section
          * (the button should now say ''Disconnect'')
    - IF YOU ARE GOING TO BE AUTOGUIDING:
          * in ''INDI Configuration'' window verify the following settings:
              * Hostname: localhost
              * port: 7600
              * driver: VATT-GUIDE-INDI
              * Port: [empty]
          * exit the INDI Configuration window

    - In the ''Main tool bar'' (it may be positioned anywhere in the window), 
      * click the ''Advanced setup'' (brain icon) button (second from the right); a new window should appear.
    - Set binning to the allowed maximum of 8x8: 
      * Select the ''Camera'' tab,
      * in the group ''Camera-specific properties'', set binning to 8 (pull down selector).
      * [Note. Ostensibly, binning can be set via ''INDI options'' as NxM where N and M may take any value you wish.  This feature does not work. Binning can really be set only via "brain"  button.]
    - IF YOU WILL NOT BE AUTOGUIDING: Disable mount guide output:
      * Select the ''Guiding'' tab,
      * in the group ''Shared parameters'' disable //mount guide output// (uncheck the box); ''Guide   output DISABLED'' should appear in the lower left of the main window. This should prevent PHD2   accidentally interfering, e.g., with the PEPSI guider.
    - Set up automatic frame capture:
      * Select the ''Global'' tab,
      * check ''Enable diagnostic image logging'', then
      * in the group ''Save Guider Images'' check ''Until this count is reached'', and
      * set the value (100 is the maximum).
      * the files are stored on the ''vattcontrol'' server
      * The Dark Library is located in the directory ''/home/vattobs/.phd2/''.
      * The directory ''/home/vattobs/PHD2/PHD2_CameraFrames...'' is automatically created for the session.
      * If you need to capture more than 100 images, make a renamed copy of the session directory; new   //fits// files should start populating the original sesson directory.
  * Start Imaging
    - in the bottom left of the PHD2 window there is a button with 2 arrows forming a circle. Click that button.
    - the button should gray out, the stop sign button should turn red, and images should start appearing
  * Start Guiding
    - change the exposure time setting and contrast slider to find an appropriate guide star.
    - Click on the guide star
    - click on the circular icon i the tool bar that looks like a target
