Has anybody had success shooting sun stars?
The instructions sound simple and straightforward. One book I have explains why you need a wide angle lens, the shorter the focal length the better, to achieve the light diffraction produced by stopping down to f/22 or so. This book showed one example shot at f/22 with a 15mm lens. The star is "nicely defined" and the underexposed sky still has good detail.
I ain't getting anywhere close. All shots are at f/22 with an 11mm lens. I am not starting to see what I'm going to call a "defined star" until I get to 3 or 4 stops underexposed and at that point most of the sky and surrounding detail is lost.
Is there more to it than short focal length and very high f-stop?
