Pentax DA 14mm F2.8 ED, Tokina 16-28 F2.8. Both are around $800 (pentax a tad less). Voigtlander 12mm F5.6 gets a lot of good reviews but a bit slow for astro unless you use a Polarie.

More expensive but the best is Nikon 14-24mm plus an adapter (I have a Novoflex adapter and it is very good).

Possibly the best is Zeiss 15mm F2.8. But these are both full frame lenses and quite expensive and heavy.

Greg.
