For a 6 minute exposure, it looks really good to me.
I think with just a small amount of practice, you will be able to get aligned much faster than 2 hours, no matter which technique you use.
I orginally started off trying to use a web cam to get aligned. Then I bought a illuminated reticle eyepiece. For me it's so much faster, intuitive and easier all round.
Of course your mileage may vary, but my main point is to stick at it. It gets easier and easier each time. Before you know it, it's second nature.
