Astrophotography entails late-night camps, clear open skies, and unexpected frames.

Shooting (for) the stars may not be the easiest thing to do. But with the right astrophotography camera, you’ll find it infinitely more rewarding.

Here’s our list of the 10 best cameras for astrophotography. Let’s pick a winner!

How to Choose the Best Astrophotography Camera

When it comes to astrophotography, you will be surprised at the wide range of options you can choose from. There are DSLRs, mirrorless cameras, and even compact cameras. Apart from the usual choices, there are cameras dedicated to astrophotography.

The most important thing is the low-light performance. ISO invariance and a high ISO option are useful features to have. A wide dynamic range is also beneficial since you don’t have much light to work with.

Also, you must be able to shoot in RAW. You will need to post-process your images, and nothing beats the RAW format in this aspect.

It helps to be comfortable using a remote shutter release as well. This minimises camera shake as much as possible.

Long exposure noise reduction is also crucial. Your camera sensor can heat up and produce hot pixels if you leave your shutter open for a long time.

You should pay attention to battery life as well. Long exposures and cold weather can drain them at lightning speed. If your battery is not durable enough, take more with you. Don’t forget to charge your battery right before your trip.

Astro filters are both sensor and lens-based. It’s practical to do some research on which system you prefer. It will influence your choice of camera.

DSLR and Mirrorless Cameras for Astrophotography

Why Choose a DSLR

A huge benefit of a DSLR is that you can modify it to suit your needs. For example, it’s possible to put internal filters in it. Clip-in filters and lens mounted ones are mostly used on DSLRs.

Usually, DSLR systems have better adaptability for astro lenses. This means that you can add more variety to a DSLR body by varying more telescopes. And you can more easily find the perfect fit for your style.

Why Choose a Mirrorless Camera

There are mirrorless systems that come with a full-frame sensor, amazing resolution, and a wide ISO-range. What can make them better than some DSLRs is that they are designed to produce less noise in low-light conditions. This is especially true for the Canon EOS Ra, a dedicated astrophotography mirrorless.

ISO invariance is also something you will find in mirrorless cameras more frequently.

Dedicated Astrophotography Cameras

There are two more systems for astrophotography. First, let’s look at the limitations.

Astro cameras are meant specifically for astrophotography. You cannot use them for any other purpose.

They also need dedicated computer software to operate.

They usually need multiple filters, which significantly raise the costs.

If you already know that astrophotography is your passion and can afford one for this niche, read on.

Why Choose CMOS Sensor Cameras

There are CMOS (complementary metal-oxide-semiconductor) astrophotography cameras with a mono sensor. They record images in greyscale. This means that if you want to shoot in colour, a minimum of 3 filters (R, G, B) are necessary.

These sensors, being more sensitive than the others, are better suited for astrophotography.

Why Choose CCD Sensor Cameras

Cameras with a CCD (charge-coupled device) sensor are more expensive than the CMOS options.

They usually need an accompanying telescopes for cameras. These cameras offer long exposure photography and have a cooler to prevent them from overheating. Their sensor also reduces the noise which often ruins beautiful astro images.
