From a light polluted city

Posted in Astrophotography with tags , , , , , , , , on 2009/07/19 by computerphysicslab

This image was taken in the center of a light polluted city with almost 1 million inhabitants. Using a dark frame of the polluted sky I could catch the Milky Way. Obviously it was impossible to observe it with naked eye.

The image is the result of adding 20 subframes of 15 seconds of exposure each one at ISO 1600. After applying a barrel distortion filter to compensate lens distortion the images become integrable. Using Nebulosity 2 software I could compensate the sideral motion of the sky.

The quality of the image is very low. The point here is not quality but the successful of avoiding light pollution in a widefield Milky Way shot. The area corresponds to the border of Lyra constellation towards Aquila constellation.
