    Hi Dave,
    
    The processing is not that much as someone would think. I don't use 
    deconvolution software or some secret unknown techniques.
    As you can see in my last Nanosail image-set posted to the list, the raw 
    image already has to be good. I try to use stacking
    of multiple exposures when seeing is favorable and when it leads to gain.
    Getting them straight off the camera and posting them is not possible as I 
    use a video device and the videofile (which is
    about 450MB first must be downloaded off the cam and then the frames are 
    subtracted for analysis.

    Ralf,
    
    I enjoy your posts, but would also like to see the raw images (if nothing 
    else to see how amazing image processing is!).

    As for publishing all of those images, can't you just zip them up straight 
    off the camera and publish that? I think that would satisfy the new rules.
    
    Keep up the good work!
