So, I'm guessing you're planning on using a DSLR. DSLR are well suited for DSOs where you need long exposures, but they don't do so well for planetary astrophotography. I believe this is what you're looking for: http://www.amazon.com/gp/product/B005HPHK92/ but if you ask me, I'd say you'd be better off spending you money on a webcam. That's what people usually use for planetary stuff.
I bought this one: http://www.amazon.com/gp/product/B005HPHK92/ and it works just fine. The one you linked just looks like a higher quality version of this.
