You really got some talent.. This is a masterpiece! You've focused everything into the middle perfectly.. The edges of this picture won't just simply need anything. I wish that I learn to do nebulas and stars like those.
It's quite easy honestly I was rather afraid people would say I got lazy on those last pics and I didn't cover rest of the image. But the point is exactly what you said, to focus in the middle, and not draw attention with the sides Thanks!
