from Casitas de Gila, April 23-24, 2012
Canon EF 15 mm f2.8 Fisheye @ f2.8, Canon-Hutech 400D body, ISO
One x 4 min = 4 min, two darks, no flats. Cropped, full resolution.
AP Mach1 Mount (the lens is really big and heavy; not :-))
This is my first shot with this Canon lens. It lives up to its reputation as a great lens for astrophotography. Sharp wide open and little vignetting.
