How to Choose the Best Camera for Astrophotography
There are key elements that you must consider when choosing a camera for astrophotography. The first one is exposure. You can think of exposure as the amount of time you allow photons to impact your camera’s sensor.
The longer you expose your camera’s sensors, the brighter the image will appear. Consequently, prolonged exposure will allow you to pick up very fine details in a low-light environment.
The second element to consider is ISO (International Standards Organization). ISO is basically the measurement of a camera’s sensitivity to light. Lower ISO means less light sensitivity and vice versa. Luckily, this setting can be adjusted in any good digital camera. Superior quality astrophotography images are captured on higher ISO.
Another important element to consider is the ability to interchange lenses. DSLR cameras will give you the option of using different lenses depending on what you want to shoot. Your requirement will dictate whether you will shoot with a wide angle lens or not. A DSLR camera or an interchangeable lens camera allows you to use different lenses.
Although using a telescope creates a natural advantage over regular photography, good astrophotography images can be captured with a camera that has the above specifications.

6. Pentax K-3II Pentax DSLR
The Pentax K-3II DSLR is a good astrophotography camera at a nice price. The camera has 24.4 megapixels allowing it to compete with other more expensive cameras. For about 800 dollars, you can pick up a great all-around DSLR that will also let you take awesome photos of the night sky. The camera also has unique features including the Astrotracer, which utilizes the built-in GPS to sync the sensor to the movement of celestial bodies.
The sensor without an anti-aliasing filter makes it a good choice because the anti-aliasing filter is usually troublesome for astrophotographers. With no anti-aliasing filter, Astrotracer, and at its low price, the K-3 II is still an amazing option for an intermediate photographer interested in taking great shots and taking the plunge into astrophotography.
Pentax K-3II Pentax DSLR main specifications and features
- 35 MP APS-C CMOS Sensor
- 2 inch 1.03m-Dot LCD Monitor
- 86k-Pixel RGB Exposure Metering
- Anti-Aliasing Filter Simulator
- Built-In compass, GPS, and AstroTracer
- Full HD 1080p Video Recording at 30 fps
- ISO 100-51200, 8.3 fps Shooting
- PRIME III Image Processor
- SAFOX11 27-Point AF, 25 Cross Sensors
- Shake Reduction & Pixel Shift Resolution
Pentax K-3II Pentax DSLR detailed review
Also on our best camera for astrophotography podium is the Pentax K-3II. The camera has a 24.35 Megapixels APS-C CMOS sensor that enables high-resolution imaging. The K-3II has notable low light sensitivity from ISO 100-51200.
In addition, the camera has a unique anti-aliasing filter that allows you to toggle an anti-aliasing filter effect. When the filter is off, the camera acquires maximum resolution and sharpness capturing an image of the highest attainable quality.
Furthermore, the camera’s pixel shift resolution and diffraction correction allow you to achieve a more refined color palette, reduce noise and increase the resolving power. The function also helps to increase sharpness by offering an effective improvement to the effects of diffraction.
Also, the SAFOX11 autofocus system allows to quickly and accurately acquire focus on a subject in a low lighting condition. It uses 27 specific phase-detection points. The light source sensor also benefits the autofocus function, helping to refine the focusing accuracy despite the challenging lighting conditions.
Accurate and consistent exposure is also enhanced by the 86k-Pixel RGB Sensor Exposure Metering. Moreover, the in-camera sensor shift type shake reduction minimizes the appearance of camera shake when using a mounted lens. The image stabilization is located within the camera body past the legacy lenses and the Pentax lenses making it ideal for working in low light conditions or when using longer lenses.
Additionally, the camera is enabled with GPS, astrotracer and an electronic compass that allows geotagging during shooting. The astrotracer function helps in making long exposures of the night sky.
The GPS, on the other hand, helps in coordination. The camera’s orientation allows the image sensor to shift during exposure hence compensating for the earth’s rotation. Therefore, star trails will not appear in the captured images. This results in clearer and sharper imagery.
Camera body of the K-3II
The Pentax K-3II’s camera body is well designed to serve the purpose. It comprises of the following:
- Magnesium alloy over the stainless steel hence making the camera weather resistant, coldfrproof and free from dust and moisture.
