    Cool!... I did one of these with the 12" LX200 and one with the 90mm.. Now
    that I know I can do it with the 90mm, I am keen to do more.. Of course I
    have a meeting tonight and school, so tomorrow night is my next night..
    
    As I told Ted in a separate email, where I sent the file he requested, I had
    entered an observation and then discovered the ability to measure from a
    camera.. Then I found my default position was not as accurate as I have it
    from Occultations..
    Etc.. I have deleted and redone the Obs twice already..
    
    Is there a way to edit observations in ObsReduce??

    Congratulations on your first positional observations.
    
    Comparing against elements less than 12 h old, reveals the following
    residuals:

    A good first effort, especially 06044A.
    
    Your 06044A cross-track residual of 0.01 deg is excellent, similar to that
    routinely achieved by the best observers.
    
    Your 91055A obs has a large cross-track error. If you will e-mail me your
    ObsReduce details file (i.e. the *.det file), and if possible the video
    frame you reduced, I may be able to spot the problem.
