    Sun's instrumental altitude with artificial horizon

    Hi dear Navigators,
    pardon me for again taking up your time!
    After studying hours my vernier mechanism I did set up an tray with black gear 
    oil, and made several tryouts with Jupiter and succeeded to get intercepts 
    like 4 - 10 minutes from my DR. I failed with Saturnus, maybe the image was 
    just too tiny.
    I was wondering if I was just lucky with Jupiter, after all this is an rather 
    old 1928 C.Plath. So I would like to verify the accuracy with bigger and 
    faster objects too.
    Now, about Sun and Moon... what is a preferable way to set images (oil/sky 
    image)through view and just what corrections should I use in order to finally 
    calculate the departure?
    You should have seen the curious look on my neighbours face by the time he saw me with sextant :-)
    Kind regards, Mika
