my first clear night test of our new Sigma fish eye lens. Seen
here is from top to bottom a full sky length 180 degree coverage,
with the right and left sides cropped by the smaller APS-C sized
sensor in the XTi. On the top of this short 10 minute exposure
is the northern horizon, the bottom is the southern horizon with
the distant glow of Phoenix low in the south west. On the right
side is the roof of my house. This was shot from my balcony on
the back of my home which is about 3 miles from down town Payson.
the center of this image from upper left to lower right is the
band of the Milky Way, with the brightest area in Sagittarius
near the bottom southern horizon.
I strongly urge
you to take a look at the largest image and see what type of
image quality this lens provides wide open. I was impressed with
its sharpness over such a huge field of view.
