I have to say Tolga amazing image. When I clicked the image to view it full-sized, wow. At first glance its a bit overwhelming, I then began to slowly scan the image from left to right, starting at the top. That's when this image comes ALIVE!
Wow, as I moved my eyes across it I begin to see more and more detail. In the spiral galaxies defined arches appear, elliptical galaxies start to reveal their center. The longer I look the more details appear, dust lanes, faint color, and I even see faint structure in a few of the smudges ( the faint fuzzies ).
I'm not an imager at all, strictly just a visual observer. I never give advise or voice my opinion about what I think an imager should or could do. As I said I just observe visually and aside from sketching at the EP, I capture/image nothing in any way. I truly admire the hard work imagers produce and choose to share with us all here. The only comments I post about images that get shared are strictly complementary. Your image will be an acceptation to my rule. The only reason is because you state you don't have enough color data. I want to encourage you to do whatever you feel will bring out even more amazing detail than what you've already captured. If you feel you can put even more details into this image by all means, go for it. There is all ready so much detail in it, the longer I look the more I see.
Images like this fascinate me. To me it's an images that deserves a second, third and fourth look. Every time I go back and look again, something new appears. A new faint fuzzie appears or dust lanes, another spiraling arm appear forming a complete galaxy.
If you can bring even more alive and tease out more detail in this already fabulous image I cant wait to see that one.
Sorry to ramble on about your image but it's one of the few I found myself going back to, to see what else I can see in it.
Great job on this image here and keep up the amazing work.
