Astrophotography Camera FAQ

You might have some questions about astrophotography cameras, like what features are most important to have and what type of camera is best for taking pictures of the sky. Here’s what you need to know.

How many megapixels do you need for astrophotography?

HOW MANY MEGAPIXELS DO YOU NEED FOR ASTROPHOTOGRAPHY?

When it comes to megapixels, it’s good to bear in mind that if you have a camera with larger pixels this will make it more sensitive to light, and that’s obviously a good thing. It will also have better signal-to-noise, as Sky and Telescope reports.

However, before you rush out and purchase a camera that has the highest megapixels, there is a case to be made for lower megapixels.

When you’re taking pictures of deep-sky objects, having a camera with a short focal length, a small aperture, and smaller pixels can work well. This is because the fast focal ratio will transmit more light to the smaller pixels, the website goes on to explain.

When taking pictures of the stars, an average amount of pixels you’ll need is between 2.5 and 2.8 pixels. Having more than that won’t increase the details you can see in the images but it will transmit more light and decrease the signal-to-noise ratio, as Diffraction reports.

What’s an average amount of megapixels you should look for in a camera?

WHAT’S AN AVERAGE AMOUNT OF MEGAPIXELS YOU SHOULD LOOK FOR IN A CAMERA?

When it comes to megapixels, you might wonder how many are really necessary. You need to consider what you intend to do with your images. For example, if you want to print them you’ll need more megapixels to ensure that they don’t look grainy.

On average, you’ll get a clear and sharp photo print by having 300 pixels per inch. That means that printing an 8×10 photo will need 8x300x10x300, which will give you 7.2 megapixels, as Clark Vision explains.

A camera needs, on average, between 10 and 20 megapixels as this is more than sufficient for your photography needs.

It’s worth bearing in mind that another reason why you don’t always need a camera with the largest amount of megapixels is because of how technology is changing and improving.

Advanced DSLR and mirrorless cameras have large sensors and this means that a camera that’s eight megapixels will be able to create a higher-quality image as compared to a different type of camera with the same amount.

Look for other camera features as they’re more important than the amount of megapixels in a camera. 

What should I look for in an astrophotography camera?

WHAT SHOULD I LOOK FOR IN AN ASTROPHOTOGRAPHY CAMERA?

A camera is not only about its megapixels! Here’s a rundown of the most important things to look for when purchasing a camera for astrophotography.

  • Aperture Size. You want a decent aperture size because this means that it will collect more light so that it can enter the camera lens. Look for a camera that has an aperture of at least f/2.8.
  • Shutter Speed. The longer the camera’s shutter can stay open, the better as this will encourage more light and capture the slow movements of celestial objects in the sky. 
  • Full-Frame Sensor. If possible, it’s a smart idea to purchase a camera that has a full-frame sensor as this is ideal for astrophotography. The reason for this is because it will collect more light due the sensor’s large size. An example of a full-frame camera is the Sony Alpha a7 IIK E-mount interchangeable lens mirrorless camera that we featured in our list of reviews.
  • Sensor Type. You want a CCD or CMOS sensor to capture deep-sky objects much better since they’re really far away from you. A CCD sensor, like the one found in the Kodak PIXPRO Astro Zoom camera that we reviewed, will excel when it comes to taking long-exposure pictures. As a bonus, CCD sensors are usually much more sensitive to light than what you’ll find in a DSLR camera.
  • Live View Mode. This feature should be available on your camera as it allows you to preview your images before you take your shots, which can save you a lot of time.
  • Small And Compact. You want to ensure that the camera you use is easy to handle and carry around, especially if you want to transport it to various stargazing locations out of the city. There are many small and compact astrophotography cameras that we featured in our guide, such as the Kodak PIXPRO Astro Zoom camera that has dimensions of 3.32 x 4.44 x 3.21 inches and is really convenient to pack and transport. 
  • Image Stabilization. You don’t want your images to look unfocused, so investing in a camera that offers image stabilization features is always a good choice to allow you to create sharper, cleaner pictures.

Is full frame better for astrophotography?

People often debate whether it’s better to use full-frame or crop camera sensors for astrophotography.

While there’s no clear-cut answer because both have their advantages, many people insist that full frame can be very beneficial for your astrophotography hobby. Here’s why.

  • Full frame gives you wider fields of view so you can see more, and when you can see more of the Milky Way galaxy or other large celestial body this will improve how well you can capture it.
  • Full frame sensors produce high-quality images. Although full-frame and APS-C cameras have almost the same resolution, because full-frame sensors are much larger this increases the size of individual pixels and this ensures better quality images when you use higher ISO, as TechRadar reports.
  • Full frame cameras work well when taking pictures in low-light situations. This is because they tend to have bigger pixels that will collect more photons, resulting in an image that’s got less noise and is cleaner as well as sharper.
  • Full-frame cameras have more dynamic range. Again, this is as a result of the fact that they have bigger pixels. Dynamic range is important because it refers to the ratio that exists between the minimum and maximum measurable light intensities, as Cambridge in Color reports. Since they can boost the dynamic range, this makes full-frame cameras perform well when it comes to displaying the full brightness of the photo you’re taking when there are very dark shadows in it.

There are some potential downsides of full-frame cameras to know about. These include how these cameras tend to be large and bulky, as well as more expensive than crop-sensor cameras.

There’s also the issue of how full-frame cameras have larger sensors that require the camera’s memory card to store more data so it takes longer to save pictures onto this card and that can cause you to be able to take fewer frames every second in “burst mode.”

However, for astrophotography you’ll want to use long-exposure photography, so this “issue” of full-frame cameras could actually work in your favor!

Should I buy a DSLR or mirrorless?

This is another important question you’ll need to answer when choosing a camera. DSLR and mirrorless cameras are both popular for astrophotography.

They both have interchangeable lenses and you can choose from a variety of models, whether you’re a beginner or professional. They both also have large sensors so that they can collect a lot of light and provide detailed images.

That said, it’s important to be aware of both of their pros and cons so that you can find the one that’s best for you.

DSLR camera

Pros

  • DSLR cameras have optical viewfinders so that you can plan the perfect shot. 
  • They have fast autofocus features.
  • They have a larger variety of accessories and lenses that are compatible with them, which makes them versatile and can also increase their lifespan.

Cons

  • DSLRs can be a bit heavy and bulky, which doesn’t always make them feel practical.
  • They can be expensive, which can be an obstacle when purchasing them especially if you’re a beginner or on a budget.
  • They tend to have slower continuous shooting ability.

Mirrorless camera

Pros

  • These cameras usually have electronic viewfinders so you can view your scene and feel more secure about getting a fantastic picture.  
  • They’re lighter and more compact than DSLR cameras, so they’re easier to carry around. 
  • They don’t cost as much as DSLR cameras.

Cons

  • Some mirrorless cameras don’t have quick-access buttons or dials.
  • They have fewer options than DSLR cameras when it comes to accessories and lenses that you can use on them.
  • They tend to have a shorter battery life than what you’ll find in DSLR cameras.

Does the brand matter what about lenses?

DOES THE BRAND MATTER WHAT ABOUT LENSES?

When it comes to camera brands, you might wonder if you should stick to certain brands over others. The three leaders of mirrorless and DSLR cameras are Nikon, Sony, and Canon.

The important thing you need to bear in mind when choosing a camera for astrophotography is that some brands now have cameras that are specifically built for taking pictures of celestial bodies. These include the EOS Ra astrophotography mirrorless camera from Canon that we featured in our reviews.

It’s good to remember that the brand of camera you choose will usually also influence the accessories you’ll be able to use with it. For example, you might find that the camera you’ve chosen will only be compatible with accessories that are made by the same brand.

When it comes to lenses, the brand you choose to use usually doesn’t matter. There are lots of brands that make quality lenses. These include Canon, Nikon, and Sigma, which is great for third-party lenses that are compatible with various camera brands.

Lenses are also interchangeable so the camera you own will usually be able to use a bunch of different lenses that are of different brands and types, such as macro and wide-angle lenses, for example.

However, it’s worth bearing in mind that you might not always be able to fit every lens you want to buy onto your camera.

You therefore need to think ahead when purchasing a camera and ask yourself what lenses you’d like to use on your camera so that you’ll be able to use the ones that are compatible with it.

Although brands don’t matter, it’s clear to see that you need to consider the brand of lens and camera you want to ensure they’re compatible. This enables you to own a camera that will be versatile for your various astrophotography needs and bring you joy for a long time. 

Conclusion

Taking stunning pictures of the night sky becomes much more possible if you’re equipped with the right kind of camera. In this article, we’ve featured five of the best cameras for astrophotography to purchase if you’re serious about capturing breath-taking images of what you see.

We’ve also provided you with more information you need when it comes to choosing the best camera for your craft. It’s worth choosing a quality camera that you love and that you can grow with in future, such as by being able to fit a variety of accessories onto it.
