Whirpool Galaxy

I would like to share with you some of the photos of Whirpool Galaxy. I had to process the raw FITS image, but it did not have enough pixels. So I made my best.

What do you think, can you see the arms of the galaxy? The first three images are my own and the last one is the picture how the galaxy looks like.
