Cool - you should be able to expose that lens for around a minute before getting excessive star trailing for a MW image. Hadn't thought of doing MW pictures with a fisheye but it's an interesting idea.

Of course the amount of exposure time that causes fishtailing varies with the focal length of the lens. With the 7.5mm fisheye, I would think it'd be about a minute. I was shooting 20 sec with a 12mm Rokinon and I could see slight fishtailing. I think I'll keep it at a max of 15 sec.

I guess I should say that probably the mount of fishtailing is the same regardless of the focal length but it seems more visible with a longer focal length lens.
