Eric, what can I say! What a superb edit. The idea had crossed my mind but I never thought that a suitable train might exist. Well done. Thank you for the kind words. My shoes are gradually drying after their soggy night. Must take wellies next time. JK, I will dig out one of the frames and post later, I don't much count the frames, I tend to run a sequence for at least 30 minutes regardless of the frame rate, that seems to provide a nice length of trail. Currently with the D3 the interval between the start of each exposure is 40 seconds, I think the Riblehead exposures were 20sec @ f3.2, so the sensor had a little time to cool between exposures, I might experiment with lower ISO and a longer exposure? The software can fill the small gaps between the exposures. I have seen star trail photographs which must have been taken all night and the image is just rings of light which os OK if that's what you want but it's very difficult to make out the constellations or identify particular stars, except Polaris of course!!! I have been eying the Milky Way, last night it was quite distinct but I think I will have to find the darkest skies possible to get anything worthwhile. Thinking in terms of making a panorama across the sky with something between 100 and 200mm, although maybe the 300 f2.8 might be able to be pressed into service? Trouble is the sky is constantly moving in a circle and tracking it could be an issue without a big polar mount. Maybe I could make something... Need to get the lathe working and thinking cap on! LOL
