Are crop sensor cameras good for astrophotography?

For astrophotography using a telescope or a long zoom lens on a tracker, an APS-C sensor is often preferable. The narrower field of view also means you’ll experience less vignetting than you would using a larger sensor. Many APS-C cameras are smaller and lighter than their full frame counterparts.

Does crop sensor affect f stop?

No, f/stop does not vary with sensor size. Nor does focal length vary with sensor size. The lens remains totally unaffected by the sensor. HOWEVER, the field of view that the cropped sensor can see and capture is seriously affected in the smaller sensor.

Do pros use crop sensors?

Current APS-C and Micro Four Thirds crop sensor cameras like the Fujifilm X-T3, the Nikon D500, the Olympus EM-1 Mk II, and the Panasonic G9 have been adopted by professional photographers around the globe, and for good reason.

How does sensor size affect astrophotography?

As mentioned many time in our astrophotography related articles, starry landscapes, star trails, planetary and deep space photography are all part of the genre. And the sensor size can impact on those kinds of photography in different ways. Field of view is obviously as important in astrophotography as in any other kinds of photography.

Is a cropped sensor better than a full frame camera?

On the other hand, for planetary and deep sky photography, a cropped sensor can help to close in on your target better than with a full frame camera. A rather inexpensive 200 mm on an MFT camera will give the same FoV of a more expensive, bulky and heavy 400 mm on a full frame camera.

How does the DOF change with a crop camera?

The only variable here is the sensor size. When using the same focal length and aperture, in order to fill the frame in the same way a full frame camera does, the photographer using the crop camera has to move farther from the subject. This increases the DoF.

Why do astrophotographers use full frame cameras?

Sensor heat is the biggest contributor to digital noise when using high ISO (gain) settings or doing long exposures – the 2 things that we do most in astrophotography. This is the reason why full frame cameras will have better noise tolerance and better low light performance than a crop sensor camera with an equivalent pixel count sensor.
