This version adds:
   - A few minor pre-release cleanups
    - Add camera data for H18
    - support for cameras with shutters, including darks and zero length exposures
    - support for Superstar/H694/H694C
       - updates installer to treat Superstar as a guide camera
    - installer automatically removes previous version if possible
    - interlaced camera (lodestar mostly) banding improvements:
      - symetric binning now reads out as progressive, which
        avoids banding problems entirely
      - an option to make the camera looked like it does not support binning
        while setting a fixed binning mode. This can be used to force a 
        program which does not support binning to bin (PHD is a fine 
        example) so you take advantage of the progressive 
        readout of binned images
      - several options to make banding better for unbinned images
          - take a second exposure for the second frame.  This elminates 
            banding but doubles exposure time.
          - apply a gaussian blur. This is useful for applications
            that try to follow stars
          - equalize odd and even frame brightness.  Because of
            chip issues, this doesn't work as well as you might think it
    - an option to square lodestar pixels so plate solvers can solve
      the images.  This is done the "easy way" - it expands the pixels
      horizontally but does not increase the apparent size of the sensor,
      so it throws away a few pixels from the right edge. Doing it the 
      "right way" is much harder, and for a guide camera didn't

      seem to be worth it.

  • The M26C will  not work. I exchanged some email with Terry Platt, and have learned that the M26C is quite different from all the previous camera and will require additional coding.  Since it it complex and I don't have an M26C to test with, support will have to wait..
