  - expose
```

  - doExposure
```
private boolean doExposure()
                    throws IOException
```
    Does an open-shutter exposure. This method calls the RPC-method StreamClient#DO_EXPOSURE_2, grabs the returned fits object and transforms it to the more general MFits java object. If a data buffer-fits is set, all of its HDU's are deleted and the new Image is added to the fits file. If no async buffer was set, a new fits file is generated with the current data. // the END card is always missing, but we want to add origin
    
    Throws:
    
    IOException
  - doDark
```
