Below you see the DeVeny Camera Control view which is the primary way for controlling and commanding the DeVeny spectrograph. In addition to direct control of the CCD, some other functions related to the instrument can be performed from this view for convenience. For instance, the TCS Offset commands can also be issued by the TOs on the TCS control panel but it is probably more convenient for the astronomer to issue them directly. The main functions available in this view are:
...
There are three motorized stages for DeVeny; Slit Width, Collimator Focus and Grating Tilt. The readouts in each widget indicate the status, motor step and encoder values (where available) for the stages. The status info is cryptic but putting the cursor on it will show a tooltip explaining the codes.

It is important to move the stages one at a time. Due to power requirements for the stages, moving more than one stage at a time is not allowed. |

The built-in offset command There are 2 types of offset commands in the TCS is absolute and has ; User and Handset. The User offsets are absolute and the the Handset offsets are relative. There are three modes; TPLANE, SIMPLE, and PA. The relative offset command is a LOUI implementation by issuing an absorb command immediately after the offset command.
It is advisable not to use the relative offset as it is unsupported relative offsets except when one is using the hand paddle as they are not supported for cases such as guided offsets.
Sending the clear command is equivalent to sending 0,0 as the parameters an absolute offset and the absorb command causes the pointing center to change to the current location and clears the current offsets in the TCS.
The hand paddle allows one to send incremental relative offsets for each of the three modes. Pressing one of the hand paddle buttons will increment the current offset parameter and send it immediately to the TCS. The hand paddle only works with absolute issues relative offsets.
The tooltips on the labels show the appropriate units for each parameter. The hand paddle text also shows the relevant units for each mode.

Similar to the TCS Offset Command widget, this widget is also presented for the user's convenience. Generally speaking the TOs issue this command on the TCS GUI.

This widget allows the user to set up acquisition of images for a focus sequence. For more detail refer to the instrument manual.
