The closest you can come to a live view is if you use a DSLR and use some software to view the captured image on your laptop-you will still have to wait several minutes for the image to be captured and then downloaded.
Remember these raw images will have noise, hot pixels, vignetting and will not look anywhere near as pretty as a finished image where a number of such long exposure frames are stacked together and then processed in photoshop or similar to bring out subtle detail
Electronic eyepices are Ok only for very bright objects. Not really worth the money IMHO
