How does it affect my scope’s viewing and imaging?[/b] [color=red]Field rotation can be visualized by thinking about what happens when a constellation or the moon rises, transits and sets.[/color] From northern latitudes, Orion will rise on his side with his left shoulder (the one north of Rigel) highest. As he crosses the sky he will reach and transit the meridian, when both shoulders will be the same height. When he sets, the right shoulder (Betelgeuse) will appear highest. It’s like he’s climbed the dome of the sky, reaching the top and then goes down the other side. The angle of his body changes during the course of the night, first tilting to the east, then tilting to the west. Similarly, the moon will rise with the Sea of Crises (Mare Crisium) edge leading upwards, the Ocean of Storms (Oceanus Procellarum) following and lower. Both of these dark areas will appear about the same altitude when it transits, then the Ocean of Storms will be higher than the Sea of Crises as the moon sets. Again the tilt changes as the moon moves across the sky. Both examples show field rotation with your head and body acting like an altazimuth mount. [/quote]

How about in your part of the world? Just google your city and say 'sunset' and the time should come up.
