For other people far from here, and serious about this little game, I suggest downloading the excellent, free and easy to use Stellarium program from http://www.stellarium.org (works on Windows and Mac) and do this simulation for your own place. A map and a compass are also useful if you plan to investigate candidate places beforehand. Use the simulation to locate the position the moon will have, especially the heading, and prepare your shooting position(s) on the map, then on the field. Good candidate places are those known to produce gorgeous sunrise shots (as I did with my sunset), or you might discover new ones as a reward. > Do you think the Pentax M 100 or 200mm (on film) would be a good lens for > that, what did you use in your GESO? > It will be just great. In my GESO (from EXIF data, therefore not very accurate): - 0024 was 100mm, slightly cropped, mostly vertical borders - 0031 was 125mm, no crop - 0041 was 125mm, almost no crop - 0048 was 45mm All this with a *ist DS with the usual 1.5 crop factor. The limiting factor here is the ability to use longer focal lengths, while still managing to include some interesting context/building/whatever in the frame. For instance, in my GESO, from where I sat, the moon did not get much closer to the church than in picture 0041, so anything longer than 135mm was useless. From another point of view, and/or with another subject in the foreground, I might have found a usage to the 80-320mm (equiv 480mm) and gotten a big moonball! But I had carefully chosen this location beforehand, and did not want to drive and run at the last minute to look for a better viewing angle (and probably miss it). In the Feb/12 case, the moon will be much farther from the sun than last Saturday. So either you shoot it close to the horizon, very early in the night, with a still dark sky, or later before sunrise, with a more colorful sky, but higher in the sky (composition may be more difficult, or surprising, or original, or all of them). > greetings > Markus > Regards, I hope you can join.
