They were taken with a Tokina AT-X 270AF 28-70mm f/2.8, pictured below. The photo was shot at f/8 or f/11 I can't remember. The lens is probably 20 years old or so, and I picked it up for $90 used on Craigslist.
I did do a little work in post to adjust color/contrast/saturation and cropped them of course. However, the stars are all natural.
