Hi Jorge, hope you got your zeds! It's a nice image, if I had one criticism (bearing in mind I'm hardly an expert myself!), it would be that the noise reduction in the processing might be a bit heavy - to me, the arms have a slightly smudgy appearance in your hi-res view, and I wonder if you've lost detail? But then my shot of the same galaxy had a comment of too much noise, so maybe it's just me!
