Astrophotography, an art and science that seeks to portray the ethereal beauty of the cosmos, presents unique challenges to photographers. Far removed from traditional photography, astrophotography demands us to capture light from celestial objects that are at staggering distances from us and are often very dim. To produce a captivating image of a starry sky, the spiral arms of a distant galaxy, or the mysterious bands of a nebula requires patience, technique, and the right equipment.
The challenges of astrophotography are numerous. To begin with, subjects are usually poorly lit, demanding cameras with the ability to capture light exceptionally well. In addition, the Earth’s rotation means that stars will appear to move across the sky during long exposures, which can result in streaky star trails. These and other considerations mean that the best cameras for astrophotography need to have a unique blend of capabilities.
Is a DSLR good for astrophotography?
DSLR cameras have been the workhorses of professional photography for many years, and they can indeed be great for astrophotography. A DSLR with a full-frame sensor can collect a lot of light, crucial for capturing those distant celestial bodies. Also, DSLRs typically have good noise reduction capabilities and excellent dynamic range, both of which are vital in capturing the subtle play of light and shadow in the night sky.
Can you do astrophotography with any camera?
Technically, you can attempt astrophotography with any camera, but the results may not meet expectations. The small sensors in point-and-shoot cameras or smartphones limit their light-gathering capabilities, which can result in grainy, underexposed images. Even among DSLRs and mirrorless cameras, not all are created equal. As we’ve mentioned, the ideal camera for astrophotography should have a large sensor, high ISO capabilities, excellent noise reduction, and a strong dynamic range.
In the following sections, we will explore six cameras that check all these boxes and are well-suited to meet the demands of astrophotography.
