That is an amazing shot...so much depth and detail! Well done...
I can never forget the first time I glimpsed at M104 around this time last year from Bortle 2 skies near Hunter Valley. Just my 8 inch SCT, but could make out the centre laneway clearly.
Was totally blown away by the fact that the exact photon that was hitting my retina on that night left the galaxy over ~30 million years ago...
30 freaking Million years ago...
our human race hadn't even evolved back then...
