I really like my 17mm & 20mm wide-angles.
I'm in a similar situation, my widest is a Minolta (AF) 28mm f2.8. If you take a look at Photodo.com, you'll find basically a library of information based on either lens mount, or makers. Looking at info of dpreview.com some months ago, apparently Sigma's new wide angle zoom is a killer (no info yet on Photodo), perhaps much better than Sony's new wide angle zoom. I assume that these will work on your camera. And depending on how much of an issue cost is, Tamron's new equivalent is apparently still quite good (again, no info on Photodo, yet).

These 3 photos and this one in particular, give a good impression of the open outback scale, but not the terrific vastness that characterises the dry, dusty interior. I head for the place called the Mundi Mundi Lookout, a short distance outside Silverton (where scenes in the Mad Max movies were staged). I only do astrophotography a few days before and a few days after a New Moon so I can find the Southern Cross and South Celestial Pole more easily (for you Northern Hemisphere guys, it's Polaris, and I wonder how difficult it would be to locate any particular star with a fisheye...?). Without a light out there (Broken Hill is about 25km away), it is a truly remarkable moment to look up and see with startling clarity, the beauty of the night sky. Having a beer or two and some crunchy munchies handy (the crunching sound keeps inquisitive wildlife away from the camera) helps pass the hour or two the camera is permitted "stargazing". Oh, and a rug, tooit's cold late at night (11-midnight)! You do need to get far, far away from the big city lights and I imagine it's pretty sleepless in Seattle...
Not sure why you're using 400iso film for astro; that makes it much more sensitive to ambient light incursions (the city e.g.).
Provia 100F at EI125 or Velvia 100F as is have done me fine for eons.

Yeah, I haven't seen to many wide primes for the A mount, mostly the MD's and so forth. While I have an SRT, it needs some repair work done on it to be usable, that's why I've just been looking at those zooms, since they're the only thing I've been finding available. Thanks for all the advice.

The five minute maximum exposure time was the result of testing earlier to see what effect the light pollution would have. Please note that this figure applies only to my area. Other locations may be quite different.
I am still jealous of what I see when looking at the photographs of the earth taken at night. The lack of light shining up into the sky from the middle of Australia is impressive. The guys in the International Dark Sky Association (IDSA) must be proud of you. About the only other similar area is Central Africa and Northern Africa and the oceans. When you look at the photographs of the earth showing the Northeast United States, Europe, California, and most other populous areas, you begin to wonder what the IDSA guys might be talking about. It is only when you get out into the night at one of the areas where light pollution is many miles away, and you see that broad band of stars we call the Milky Way, that you finally begin to understand what the IDSA guys are trying to reclaim.

When they ask you; "How many Mega Pixels you got in your camera?"
just tell them; "I use activated silver bromide crystals tor my image storage media."
