— Not the most impressive dynamic range
Although the Canon EOS 6D Mark II is half a decade old, this mid-range DSLR remains an excellent budget-friendly choice for astrophotographers. It’s one of the lightest full-frame DSLRs on the market, has an impressive ISO range that makes it good for shooting late at night, and since it's a EF-mount lens, the glass that it utilizes is significantly more budget friendly than some of the other options in this buying guide. The vari-angle touch screen also makes it easy to compose images without having to use the optical viewfinder, and although it lacks 4K video capabilities, it does offer interesting features like a 4K time-lapse mode.
Things to Consider Before Buying the Best Cameras for Astrophotography
Many of the most hyped up specs found on modern day cameras are irrelevant when it comes to astrophotography — meaning the most expensive and newest model might not always be the best suited for shooting late at night. For example, when you’re shooting astrophotography, your camera is going to be mounted on a tripod, so specs like in-body stabilization, or extremely fast autofocus won’t hold much weight. Here’s what you should be paying attention to before you purchase a camera for astrophotography.
Megapixels and Sensor Size
Generally speaking, a camera with a larger sensor will perform better at higher ISOs than a camera with a smaller sensor. Having a camera that can produce an image with limited noise at a high ISO is important for astrophotography. When you shoot late at night, you will likely push your camera to a high ISO, so that it can capture subtle nighttime detail. Cameras with large sensors deliver more pixels and better detail. Larger sensors also mean that the camera is more efficient at collecting light to produce high-quality images.
Mirrorless vs. DSLR vs. Dedicated Astrophotography Camera
When it comes to astrophotography, the debate over whether mirrorless or DSLR is better is sort of a moot point. Generally speaking, a mirrorless camera will have a lightweight body, but will be pricier than an older model DSLR. A DSLR will generally have more lens options — and with astrophotography the lens that is attached to your camera is typically more important than whatever body you are shooting with. Many of the advanced settings found in mirrorless cameras aren’t really relevant to astrophotography either. A third option that is overlooked by many photographers, is a dedicated astrophotography camera. These cameras attach to a telescope and give photographers the tools to capture objects in deep space that can’t be viewed with the naked eye.
Q: How many megapixels does a camera need for astrophotography?
A camera that can shoot more megapixels will ultimately give you a more detailed image, which is something that’s pretty important in astrophotography. While a 45.7- megapixel camera will render more detail in your shots of the sky, these files will also take up more hard-drive space to store. Most modern mirrorless cameras with a 26-megapixel sensor will give you plenty of details for astrophotography, but more megapixels certainly won’t hurt. If you’re looking for the most pixels, just expect to pay more up front for your camera, and have ample hard drive space to store those large files.
Q: What kind of camera is best for astrophotography?
An astro-specific camera that can be mounted to a telescope is probably the “best” at astrophotography, as it will get you the clearest shots of the night sky. Unfortunately these cameras are only designed for this purpose and won’t be nearly as versatile as some of the DSLRs and mirrorless cameras that can be used for astrophotography. They also require that you own a telescope to mount them on. If you’re planning to shoot the stars with a DSLR or mirrorless camera, look for something that has high ISO capabilities and is good at controlling image noise.
Q: Can any camera do astrophotography?
Most modern DSLRs and mirrorless cameras are a good fit for astrophotography because of their large sensor sizes, high ISO capabilities and control of image noise.
Q: Is mirrorless better for astrophotography?
Mirrorless and DSLRs are both fine choices for astrophotography, but realistically there are a lot more mirrorless options currently on the market. A modern day mirrorless camera will do a great job in low light conditions, and is more compact than a DSLR, making it easy to travel with. However, older DSLR models will often have large sensors and can be found for better deals on the refurbished market.
Q: Which is better for astrophotography, Canon or Nikon?
Canon and Nikon both produce great cameras that can be used for astrophotography. Which is better is really a matter of preference. For many photographers it comes down to what lenses they already have in their collection.
Q: How do I start astrophotography?
Getting started with astrophotography is easy — head to a place with limited light pollution, grab a tripod to stabilize your shots, and start shooting. For a related tool, here is our guide to the best binoculars for astrophotography.
Q: What gear do you need for astrophotography?
In addition to a camera that can handle shooting at high ISOs with minimal noise, you will want a wide, fast aperture lens and a tripod — so that you can stabilize your long exposures as you capture the beauty of the night sky.
Final Thoughts on the Best Cameras for Astrophotography
The specs and settings that make a camera good for astrophotography are very different from what makes a camera good at other forms of photography — meaning you don’t necessarily need to splurge and get the newest or most expensive camera on the market to get gear that will be great at capturing the night skies. When shopping for a camera for astrophotography, the most important specs to consider are its sensor size, megapixel capabilities and its ISO range. The crucial thing to look for is a camera that will perform well and create low-noise images when it is operating at high ISOs. For a great budget pick, consider the Canon EOS 6D Mark II, which is a capable and classic option that still promises strong results. If you’re looking for a great option to use with your telescope, the ZWO Optical asi183mc Pro will go farther than the competition. The Nikon D850 on the other hand, is our overall favorite for most people for its power and versatility.
