Rokinon 500mm F6.3 Mirror for Astrophotography?

I just bought a Pentax K-X and am in the process of getting some nice (cheaper) lenses.

One of my interests is astronomy and I'd like to use this camera for some large field shots of the night sky.

I was wondering if the mirror lenses would work well for this application? They are very similar to the smaller catadioptric telescopes available, so I think they should work great.

I have a heavy duty Manfrotto tripod for shorter exposures and I'm buying a nicer equatorial mount for one of my scopes that I can piggy back the camera onto for longer exposures.

Anyone used a mirror for star shots yet?

Don't have this lens, but I know this has been discussed before. Check out this thread for a link to the review page for this lens and to the Mirror Lens Club.
