    Greg,
    
    May be its worth to try different settings. Since there will be
    twilight I would tend to open the aperture. I do however not know
    whether a different aperture may eventually also have an influence on
    the calibration which you obtained with F22. I think its just
    worthwhile to try it. After reading Frank's comment on "Digital
    camera: stars in daylight" one might eventually also try to use the
    tif-format instead of jpeg, provided your camera has this option.
