Over the past 6 months or so I've been submitting jobs to the [Bradford Robotic Telescope]. Its quite nice as you get to choose your exposure settings and then just sit back and wait. Depending on what you request (you have to think about when the object is in the sky etc) you get the images back within a few weeks. The image quality is never going to be completely stunning since you can only request up to 2 minutes but for the amateur who doesn't have the kit to take astrophotographs this is fantastic. A 2 minute exposure with this telescope actually allows you to go fairly deep. Once the image is taken you get a pre-processed jpeg and a the raw FITS files which you can then manipulate in your favourite package. Anyway, here are a few images...
M4 - globular cluster in the constellation of Scorpius (60s, r-band image).
M57 - the Ring Nebula (120s, RGB image)
