Lenses for Astrophotography

     Astrophotography Lens Test

A test of wide-angle lenses for astrophotography on FX format. The shots were taken from suburban conditions, the camera was mounted on a static tripod without guiding. The left image is always the full frame, the middle one is the center, and the right one is the upper left corner of the image.

M13 was clearly visible with indirect vision with the unaided eye. Read More
