Yes, there are a number of readily available adapters that will fit just about any brand of camera to a telescope. Amazon has some if you search for Canon Telescope Adapter. The key to remember is that any adapters you will use will render auto-focus, and aperture control unusable, so you will need to tinker with ISO, shutter speed and focus manually. Don't let the camera select shutter speed or ISO. Keep the ISO low and you will likely need to use very long exposures.
