  • So you want to -- photograph the ISS in front of the Sun or Moon

    [UPDATE 2013/12/20] Predicting the position of the Sun & Moon isn't all that difficult with a bevy of apps & websites to help you. Predicting satellite positions, incl ISS, is more specialized. Several tools of the SOFTWARE TOOLCHEST come in handy and I will have to add some new ones for this task. Once you know WHEN & WHERE it will happen, the next task is to figure out HOW. Especially when you aim to shoot a transit in front of the Sun, extra precaution is needed.
