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? ps. You should have seen the curious look on my neighbours face by the time he saw me with sextant :-) Kind regards, Mika D.R.
