Astrophotography with Clouds

Well, this is one astrophotograph I managed to take between the clouds with my 50mm lens. The image has some barrel distortion because of the aperture of f/1.2 I used.
The exposure was about 8 seconds (multiple stacks) but I cannot remember the ISO at all; I think it was ISO2500.

Here is a cropped image of the stars field.
