"The only time I've seen anything close to this is from someone like Robert Gendler, who uses a remotely controlled 20inch reflector telescope and stacks images taken from an SBOG camera."
Actually obtaining images like this with a camera and lens are fairly straight forward. See this link for an example usin g a DSLR and tripod: http://www.redbubble.com/people/ccdo...rd-dslr-camera
It's far better if your camera rides piggy-back on a tracking telescope or on its own tracking mount. Then very long exposures with pin-point stars are possible. Dark skies are a prerequisite and filters such as there can be of help: http://www.scopecity.net/astronomy_o...ebular+Filters
