April 8, 2012: Star Trails against Light Pollution

I took a one-hour exposure image of the stars to show how light pollution in my area awash a large part of the sky reducing stars’ visibility.

In the photo, you can see that trails from Sirius (the brightest star in the night sky with magnitude -1.5) and Venus (brightest planet in the sky with magnitude -4) are still clearly visible. On the other hand, this is not the case for other bright stars like Betelgeuse (magnitude 0.4) and Rigel (magnitude 0.1). Hence, because of the effect of light pollution, it is very impossible to image and produce long star trails in my area.
