Have I misunderstood what you have said perhaps?

I was assuming you went with the intention of photographing the comet .If so laptop +dsusb would be no great effort if you want perfect focus for that one great image. I find that for stars in the camera viewfinder of atypical DSLR like a canon 350D , a right angle focus magnifier 2.5x helps but is no guarantee of focus as the texture of the screen limits your focussing accuracy. in some older film SLR's you could replace the focussing screenfor one finer.The stilleto focusser mentioned in a previous post would need a fine texture screen to do it justice!
