How Many Megapixels are Needed for Astrophotography?

As we know, digital cameras (including the ones for astrophotography) will capture images on an array of light-sensitive dots on the camera’s sensor, called pixels.

There are two main factors to consider when discussing these pixels: the size of an individual pixel, and how many pixels the sensor possesses.

Due to advertisements and marketing jargon, we tend to not look for the term ‘megapixels’ when reviewing consumer cameras. Megapixels refer to the number of pixels of the camera’s sensor, to be exact, 1 megapixel (MP) means that the sensor has 1 million pixels.

The thing is, the megapixel rating doesn’t solely dictate the quality of the camera. A low-quality 20-MP camera, for example, can be much worse than a professional-quality 5-MP camera. As discussed above, the size of the pixel also matters, and in an astrophotography camera, the size of the pixel matters much more than the number of pixels on the camera. Why?

The larger the pixel, the larger the field of the sky you can capture, and the more polished the level of detail you can get. Another important factor to consider is that high-end astrophotography typically combines multiple exposures of different sections of the sky to make a mosaic image.

With this process, even if we don’t have a large number of pixels, we can get a really high-resolution image. This is made possible by a stable and accurate mount that is typically used in astrophotography, so capturing multiple side-by-side images shouldn’t be an issue.

So, megapixels shouldn’t be the primary factor when choosing between different astrophotography cameras, but you should instead look at the size of the pixel.

Also, having a stable mount/support for the camera is very important in astrophotography. This is why in astrophotography, full-frame and larger-sensor cameras like APS-C are preferred.

DSLR vs Mirrorless: Which is Better for Astrophotography?

There isn’t a simple one-size-fits-all answer to this question, as there are various advantages and disadvantages to both DSLR and mirrorless systems.

It’s no secret that in recent years, mirrorless cameras are becoming increasingly popular, and technology-wise, they are getting better and better.

However, to understand the differences between the two, let us first refer to the chart below:

Better battery lifeBattery lifePoor battery life
More choicesLens choicesFewer lens choices at the moment
Older technologyTechnologyNewer, continuously advancing
Typically more durable and robustDurabilityLess durable, smaller second-hand market
LargerDimensionsMore compact
Traditional viewfinderViewfinderElectronic viewfinder

So, the answer will ultimately depend on your preferences and astrophotography needs.

For example, if you want a durable body prefer a traditional (optical) viewfinder, then DSLR might be a better bet. Instead, if you want a longer battery and something lighter, then go for mirrorless.

Nowadays, you can quite easily find both mirrorless and DSLR cameras in various price ranges, so you’ll most likely find one according to your budget.

A special concern in astrophotography is that if you often go to night-long observations, then the DSLR’s longer battery life can be a huge advantage. You can easily use a DSLR for the whole night with just one or two spare batteries while you might need more spares (meaning, more money) with mirrorless cameras.

However, the high-ISO in newer mirrorless cameras can also be a great advantage for astrophotography, so purchasing those extra batteries or a charging unit might be worth it in the long-run.

So, figure out your needs and preferences before deciding on whether you’d want a DSLR or a mirrorless.

How to Take Good Astrophotography Pictures at Night?

First and foremost, even if you have the best, most expensive camera designed for astrophotography, you won’t be able to make the most of the camera if you don’t use the right settings for night photography.

While the settings may vary depending on your camera model, here are the five most important ones:

  1. Manual: avoid using automatic shoots at all costs, as it will typically confuse the camera. Make sure to switch to your camera’s manual settings.
  2. Tripod: make sure to use a strong tripod especially in windy conditions, or find other ways to stabilize the camera as much as possible. You’ll use slow shutter speeds, so if your camera isn’t stable, it will result in shaky photos.
  3. High ISO: you can start at around 800 ISO, and depending on the light conditions, crank it up if it’s still not enough. Remember, however, that the higher ISO you use. The more noise you’ll see in the final image. This is where having a high-quality camera can allow you to get clear photos even at a very high ISO.
  4. Slow shutter speeds: you might need a very long shutter speed of more than 10 seconds depending on the object you are trying to capture and the amount of available light.
  5. Wide aperture: obviously this will depend on the lens you are using, but typically wider is better. We’d recommend lenses that can open as wide as f/1.2 – f/1.8, with f/2.8 being the bare minimum recommendation.

Also, here are some useful tips to improve your astrophotography:

Be patient 

Astrophotography and night photography, in general, requires patience. Don’t rush things and give yourself enough time to get the right settings and take a lot of test shots to capture that perfect photo.

As we can see above, astrophotography settings would typically be more ad-hoc rather than a one-size-fits-all thing.

Aperture priority 

While we’ve discussed that you should try manual settings in astrophotography, you can try using auto aperture priority to help you, which can be useful when you are just starting out and getting the grasp of things.

Choose a wider aperture and let your camera adjust things automatically.

Get a remote 

As we have discussed, stability is very important in astrophotography, and even with a very stable tripod, your hands can cause a camera shake when you press the shutter button.

You can get a shutter remote or a release cable to keep your camera stable at all times.

Exposure bracketing 

If your camera has a built-in exposure bracketing, you can try using it to help in getting the right amount of exposure. If not, try playing with your camera’s exposure compensation settings.

Bulb mode

If your camera has this feature, bulb mode allows us to keep the shutter open as long as you hold the shutter button. Typically by default, the shutter will close after 30 seconds or so.

This is useful, for example, if you want to capture star trails.


Selecting just one astrophotography camera out of the ten in this list is indeed a very daunting task. There are so many different products available in the market, and each product offers its unique take on producing high-quality, sharp images at high ISOs and making the camera as stable as possible, among other important features.

We hope we’ve provided enough information for you to make an informed decision.
