Camera Notes

CCDAutoPilot gets its filter and binning information from the Camera Control Program when it first connects with your actual camera connected.  It will save that information in the system profile so that you can use that profile for session planning.  However, the camera control program automation interfaces do not allow changing the filter names or binning back.  At this point in their development, the only alternative if you have different cameras with different filter sets or names is to manually enter them in the camera control program.  Hopefully that will change in the future.  When it does, CCDAutoPilot will be updated to handle it.

Camera Sensors

The Sub-exposure calculator needs to know sensor characteristics for your camera.  A starting list is provided in a file called sensor.ini, located in the CCDAutoPilot4 program folder, typically C:\Program Files\CCDWare\CCDAutoPilot4.  There is space for 32 entries.  While it will be updated from time to time, you can enter your own data if you wish.  The file should be edited in notepad or similar text editor, not Word.  Make a backup copy before editing, just in case something goes wrong.  The four entries are separated by a comma with no spaces and must be numeric data.  The last entry should be a blank line.  The four entries are:
  • Sensor name
  • Dark signal in e/pixel/sec
  • The temperature in Centigrade at which the dark signal is measured
  • The dark signal doubling temperature in Centigrade times 10.  In other words, if the dark signal doubling temperature is 6, this entry should be 60.

    Some sensors have been superceded by new versions by the sensor manufacturer.  The new version typically has the same or better performance characteristics as the one it replaces.  Some examples are:
    KAF11002 replaces KAF11000
    KAI4021 replaces KAI4020


    Specific Hardware Notes

    SBIG STL with Remote Guide Head and Off-axis guider


    When using an SBIG STL-series camera with the SBIG remote guide head and an off-axis guider such as the Astrodon MOAG-A, be sure to orient the remote guide head so that its connector is closest to the STL body, as shown at left.  Select "Off-axis Guided" for the guide method.

    FLI ProLine and Apogee Alta cameras
    Some large format sensors benefit from having a selectable readout mode to reduce residual bulk imaging (RBI).  See the Readout Mode topic for more information.

    Maxim v5.05/5.06.
    There is a bug introduced in Maxim v5.05 that resets the guider binning to 1 upon program restart.  If you simply change the binning to 2, the guider will be sub-framed to 1/4 of the active sensor, resulting in possible loss of guide star.  When starting or restarting these versions of Maxim, be sure to reset the guider binning to 2 and hit the reset button to get your full guide chip again.  Diffraction Limited is aware of this issue and it will be resolved in Maxim 5.07.
