Breathtaking. This image is an excellent demonstration of the progress we've seen over the past ten years in digital SLR imaging. Nearly 15 years ago my university astronomy club acquired some CCD imaging equipment worth several thousand dollars, and we didn't quite achieve such beautiful images (admittedly we probably didn't push the limits of that equipment). This picture was taken with a $1200 camera (the Canon 60D) that you can buy off the shelf. I'll be interested to see shots taken with the 5D Mark-III, which claims to deliver unbelievable low-light performance. I haven't seen much activity with that model yet... Perhaps what amazes me most is that there is such a variety of low-cost cameras that allow any person to stand in their own yard and see for themselves the hidden universe that surrounds us -- and not just see it, record it!
