Camera Lenses

Camera lenses excel at wide-angle shots, such as Milky Way Photography and nightscapes. The key to capturing a great photo with a camera lens like this is the star tracker, which compensates for the rotation of the Earth and a moving sky.

Some of my favorite lenses for astrophotography include the Sigma 24mm F/1.4 Art series lens and the Rokinon 135mm F/2 mid-range telephoto.

The biggest difference between using a camera lens and a telescope for astrophotography is that camera lenses have a much more complicated design, incorporating many extra things that are not useful for long-exposure astrophotography (such as auto-focus).

A telescope (such as an apochromatic refractor) was designed to capture images of space without any chromatic aberration. The simplified design maximizes the field to create a flat image with stars that look great from edge to edge.

Not all lenses perform well at night, but with the right approach, even a cheap camera lens can produce incredible results.

If you already own a DSLR camera and lens, many suitable astrophotography projects exist. At a focal length of 150mm and above, the larger deep-sky objects begin to reveal themselves in a long exposure image.
