Best Cameras for Astrophotography

We all like gazing up into the night sky, whether for inspiration, a sense of calm, or simply to be reminded of how big the enigmatic galaxy truly is. Nothing beats capturing the ideal image of a starry night sky, a flaming constellation, or a swath of flashing white lights and vibrant colours. However, if you want to become serious about astrophotography — that is, if you want photographs that show the actual beauty of space rather than simply some hazy lights – you will need a good camera. This means no iPhones, and disposable cameras are definitely out.

The good news is that in this day and age of technological technology, it has never been easier to capture a perfect snapshot of the celestial wonders visible at night. There are several cameras available today that can take amazing low-light images (or even in pitch blackness). In certain situations, they’re even reasonably priced — you won’t have to break the bank to have one. Any electronics store will have a plethora of options for technologically powerful cameras that were formerly reserved for astronomers and NASA experts. What formerly took up a full room in an observatory can now be held in the palm of your hand.

Before you rush to the nearest electronics store and buy the most costly or fanciest-looking camera you can find, there are a few things you should consider. Whether you are a seasoned professional looking for a new camera or a novice interested in astrophotography, you will want your subjects to be crisp and visible, whether it is the Milky Way, the fiery red orb in the sky known as Mars, or stellar constellations. You’ll need the best camera for the job, one that’s tuned to your precise (cosmic) requirements.

Best Cameras for Astrophotography 2021

1. Canon EOS Ra

Canon’s last specialised astrophotography camera, the Canon EOS 60D, was released in 2010 — a powerful but crop sensor camera built on decade-old DSLR technology. The Canon EOS Ra, on the other hand, is an Astro camera with a massive 30.MP full-frame picture sensor — a luxury in the realm of astrophotography. The infrared-cutting filter has been updated to allow four times the quantity of hydrogen 656nm alpha photons, allowing a higher transmission of deep red IR rays without the need for specialised lenses or accessories. It also has a 30x zoom on both the rear screen and the electronic viewfinder, as well as the ability to record crisp 4K video. Some of the more specialised third-party software is still catching up to Canon’s RAW files, and you’ll need to make sure your optics can support the larger sensor’s picture circle (though there are in-camera cropping choices), but this is a clear winner for shooting the stars.

2. Sony A7 III

$1,998.00
Amazon
Until the release of the Sony A7 mirrorless camera, the top astrophotography cameras were all DSLRs. The Sony A7 III, the camera’s most recent model, takes low-light performance to the next level by combining a full-frame sensor with extremely high ISO capabilities. Its 24.2MP full-frame Exmor R CMOS sensor and ISO 51,200 – extendable to 204,800 – are the key reasons why astrophotographers like it (these very high ISOs even make it possible to video the night sky through a telescope using the A7). The camera’s compact size (650g) and three-inch tilting touchscreen are particularly appealing — the latter is especially beneficial when shooting upwards at night. This camera is on our list, though, due to its ridiculous ISO. It is, nevertheless, a pricey alternative, especially when combined with the Zeiss Batis 18mm f/2.8 wide-angle lens. Choose the Sony A7 II or the original Sony A7 to save money.

3. Nikon D850

$2,996.95

Mirrorless cameras do not have a monopoly on the market. There are still some wonderful DSLRs for astrophotography on the market, and the D850 has to be one of the best. Its full-frame 45.7MP sensor continues to produce some of the greatest shots we’ve seen from a camera, and while the ISO isn’t the best we’ve seen, it’s still extremely well regulated. It can also shoot at an extended sensitivity range of up to 108,400 (Hi2), with an ISO ceiling of 25,600. The build quality is superb, as is the handling – those shooting in low light will like the illuminated body-mounted controls, which can be simply turned on, and the huge and bright optical viewfinder will make framing up easy. The AF performance is excellent, however, the cumbersome focusing speed when using the back screen detracts from it. The battery life is excellent, with over 1,000 shots per charge – something that even the best mirrorless cameras will struggle to match.

4. Fujifilm X-T4

$2,148.00
Amazon
The X-T4, Fujifilm’s flagship mirrorless camera, is a fantastic all-arounder and an excellent choice for astrophotographers. While the 6.5 stop in-body image stabilisation technology won’t be of much use if you’re shooting with a tripod, the innovative vari-angle touchscreen will make it a joy to frame images in both landscape and portrait mode. The X-classic T4’s body-mounted controls make it a joy to use (and a little easier to set up in the dark), and the image quality is excellent. The 26.1MP APS-C sensor performs admirably, and there is a wide range of fast prime lenses available to complement the X-T4.

What to look for in a Camera for Astrophotography

2021 is a fantastic year for amateur photographers of all types, including those who want to capture the boundless beauty of the great beyond. Starting out is not as difficult as you may believe. With the correct camera and lens, you could be photographing the Horsehead Nebula by 6 p.m. tonight!

When choosing an astrophotography camera, there are a few factors to consider. You want your photos to be crisp and colourful, so you’ll need a camera that works well in low-light circumstances. In essence, you want to capture a photo with a lot of brilliant, sparkling colours and dramatic hues that don’t blur. The following are the important items to look for:

ISO

ISO is a phrase that few people who are new to photography will be familiar with. Consider ISO to be the sensitivity of your camera’s sensor. This is the mechanism responsible for capturing very weak and distant photons. Have you ever taken a cellphone photo of a city at night from a rooftop and been horrified by the blurry lights and foggy quality? This is due to the fact that your phone has an extremely low ISO.

You will get images with brilliant distant lights if you buy a camera with a high ISO rating. A high ISO setting will pick up stars far out in the night sky just as good as, if not better than, your naked eye. This is essential for photographing black skies and capturing clear shots of the stars.

Type of Sensor

Sensors are almost as complicated as ISOs. In general, most full-frame DSLR cameras will have a powerful enough sensor to capture images of the stars and moon. Consider a nighttime beach with an incredibly brilliant photo of the moon hanging on the horizon — this is feasible with most sensors if the suitable shutter speed and ISO setting is used.

However, if you intend to take your astrophotography seriously and capture images of distant galaxies and flashing star clusters, you will require a bit more from your sensor. This is for those who desire to experiment with “deep-sky” astrophotography. The term “deep-sky” refers to more than just the boring ol’ moon and the few stars we can see from our porches. It entails going so far as to photograph the more intense light show way back in outer space. A CCD or CMOS sensor will be required for this.

Both a CMOS and a CCD are great for long-exposure photos. They are more professional and technologically advanced than other types of sensors. It is vital to realise that these remarkable sensors will cost you much more than a conventional low-light camera. Nonetheless, they will make a significant impact in the quality of your photos.

The Image Sensor’s Dimensions

The size of your camera’s sensor is as significant as the type of sensor. The quality of the sensor, like everything else, will vary greatly from camera to camera. Nonetheless, it is not overly complicated. There are two primary sensor sizes available: full-frame sensors and crop sensors, generally known as APS-C sensors.

A full-frame sensor is recommended for our objective of purchasing the greatest astrophotography camera. The reason for this is that a full-frame sensor allows your camera to collect more light, which is essential when photographing the night sky (because of the absence of light). In addition, the full-frame sensor has higher ISO capabilities. The depth field provided by a full-frame sensor is not ideal, but it has no bearing on your cosmic photographs.

Crop sensors are typically 2.5 times smaller than full-frame sensors. While these sensors are excellent for zooming in and providing a wide field of view, they do not capture as much light. These are not at all suitable for astrophotography.

The Shutter Speed

This is a significant one. The shutter speed of your camera determines how much light enters and how much light is processed by the sensors. You may have observed other photographers in action and noticed how the shutter closes while not in use, then opens to snap an image. This is done to preserve the camera’s sensitive mechanisms, such as the sensors. The shutter is responsible for the famous ‘click’ sound heard in each photograph.

While sports and other forms of motion photography necessitate a lightning-fast shutter, astrophotography is the polar opposite. The galaxy isn’t moving anywhere fast (as opposed to a race car or a football player). As a result, you want the shutter to stay open for as long as possible. This allows your camera, sensor, and processors enough time to capture the light shining at you from millions of light-years away.

The Dynamic Range

Color, tones, and colours are all referred to as dynamic ranges. When we talk about the dynamic range capabilities of your camera, we’re referring to how much brilliant colour and sharp tones can be caught.

With a large dynamic range, you can catch all the minute details of shadows, wispy cosmic tendrils, and delicate colour highlights that your eyes can barely notice. As you may expect, this is critical when practising astrophotography. You want all of the bright oranges, cool blues, and neon greens of space to stand out in your images. A limited dynamic range will result in grainy, amateurish photographs with indistinguishable colour splotches and a lot of smearing.

The Number of Megapixels

This is most likely the place you are most familiar with. We’ve all heard about megapixels; they’re the key selling point for every new smartphone. But what exactly are they, and what do megapixels imply in the world of astrophotography?

The higher the number of megapixels your camera records, the more detail will be shown in the final image. Because of its large megapixel count, 4K and 8K photos offer such remarkable detail. If your camera does not have enough megapixels, it will not be able to produce images that are huge and full of complex features and vibrant colours.

It is critical that your camera capture enough megapixels to take a stunning shot of the distant stars and planets, as well as all the light they generate. This will provide you with the high resolution you require to get the most out of your astrophotography.
