We analyzed all 685 images shortlisted for the Astronomy Photographer of the Year competition in the past five years.
Our goal is to find out what equipment is being used by the best astrophotographers in the world today. They are producing amazing images and you want you to be able to too.
We have looked at what cameras, telescopes, mounts, and star trackers have been most used from 2018 to 2022.
See below for a summary of the key findings and read on for a more detailed analysis.

Read on for more detail on each of these findings
The Sony A7 III is the Most Popular Astrophotography Camera in 2022
The most used individual DSLR/mirrorless models in 2022 are Sony models, with the Sony A7 III in the top spot.
25% of all shortlisted images using a DSLR or mirrorless camera in 2022 used either the Sony A7 III or Sony A7R III.
You can see the top models this year:
From 2018 to 2021, the Canon EOS 6D was the most used model and is the most successful camera when looking at all five years of data:
Yet the Canon EOS 6D has dropped off completely in 2022, reflecting it being an older model.
For more insight on cameras using this data, see our article on the Best Cameras for Astrophotography.
Mirrorless Cameras Overtake DSLRs for the First Time
In 2022, for the first time, mirrorless cameras became more used than DSLRs in the competition.
This year 52% of images used mirrorless cameras, versus 48% for DSLRs.
This may only be a narrow majority but every year previous DSLRs were more used. In 2018 it was 83% DSLR vs 17% mirrorless.
You can see a clear trend in this year-by-year chart below:
This reflects the growing shift in photography of mirrorless cameras becoming more popular than DSLRs. Mirrorless cameras have become more affordable in recent years and are smaller and lighter.
DSLR and mirrorless cameras are mostly used for landscape astrophotography. For example, this photo of the Milky Way core in the sky above the earth taken with a Nikon Z6 II:
For more information on this, see the Best Mirrorless Cameras for Astrophotography.
Sony Camera Use Increases Every Year
Sony cameras have become significantly more used over the past five years. This likely reflects the dominance in the mirrorless market of Sony models.
Sony camera models make up 38% of all images taken with DSLR or mirrorless cameras in 2022. This is up from 17% in 2018.
As you can see, there is a noticeable jump in 2022:
If we look at the manufacturers of mirrorless cameras used, we see Sony’s dominance again:
If we look at the mirrorless models used in 2022, Sony still has the vast majority but Nikon is taking a greater share:
Canon Cameras Used Less And Less Each Year
The use of Canon cameras has decreased over the years in the competition.
In 2018, 53% of the DSLR/mirrorless images used Canon cameras, in 2022 this is 17%:
The previous dominance of Canon was largely due to the popularity of the Canon EOS 6D and Canon EOS 5D Mark IV.
As these cameras have aged it seems as though astrophotographers have moved to newer Sony or Nikon mirrorless cameras, rather than more recent Canon models.
Nikon has had the top spot for most used cameras for the last three years running.
Nikon DSLRs like the D750, D850, and D810 were very popular with astrophotographers. Now the mirrorless Nikon Z6 / Z6 II and Z7 / Z7 II models are too.
ZWO Dominates Planetary Imaging
By far the most successful manufacturer of planetary cameras is ZWO, as you can see in this chart:
ZWO specializes in dedicated astronomy cameras. Five of the top seven most used models for planetary imaging are from ZWO:
The ZWO ASI174MM is the most used model for planetary imaging. This is a 2.3 MP resolution, uncooled, monochrome, dedicated astronomy camera.
For a deeper dive, see our article on the Best Planetary, Lunar & Solar Cameras.
ZWO Cameras Lead for Deep Space Imaging
ZWO cameras are also the most used for deep sky imaging:
The most used individual camera models for deep sky objects (DSOs) are the ZWO ASI1600MM Pro and the FLI ProLine 16083:
The ZWO ASI1600MM Pro is a cooled, 16MP resolution monochrome, CMOS dedicated astronomy camera.
The discontinued FLI Proline 16083 was a cooled CCD dedicated astronomy camera. There are now other models from FLI available in the Proline range.
If you want more information on any of this, see our article on the Best CCD and CMOS Cameras for Astrophotography.
Celestron is the Most Successful Telescope Brand
Turning now to telescopes. Celestron models are the most used, with Takahashi in second, Sky-Watcher in third, and PlaneWave in fourth:
As for telescope types, apochromatic refractors and Schmidt-Cassegrains are the two most used:
See further below for how this breaks down for planetary vs deep sky imaging.
The Takahashi FSQ-106 is the most used telescope model in five years of the competition:
It is a quadruplet apochromatic refractor telescope.
See the Best Telescopes for Astrophotography for more insight on this topic.
Celestron Telescopes Dominate Planetary Astrophotography
Breaking this down now to planetary imaging, we see that Celestron telescopes are the most used, followed by Sky-Watcher models.
40% of all shortlisted planetary images use Celestron Schmidt-Cassegrains (SCTs).
This is then reflected in the top telescope types for planetary imaging, with Schmidt-Cassegrains (made by Celestron) at number one:
The high-aperture Celestron C11 and C14 Schmidt-Cassegrains are the most used models for planetary imaging:
The C11 is an 11-inch aperture SCT, the C14 is 14-inch, and the C8 is 8-inch.
You can buy them as standalone OTAs or as part of packages with a mount included.
There is also a 9.25-inch version in this range (the C9.25) and there are also EdgeHD versions that are coma corrected.
For more on this, see the Best Telescopes for Planetary Imaging.
Takahashi & Planewave Dominate Deep Sky Telescopes
If we look at telescopes for deep sky imaging we see Takahashi and Planewave leading:
Apochromatic refractors are the most used telescope type for deep sky, followed by imaging newtonians:
Apochromatic refractors and imaging newtonians are both telescope types that can be acquired relatively cheaply and so are accessible to more people (although many premium models are very expensive).
You can buy these telescope types relatively cheaply. This makes them more accessible to more people. Although many premium models are very expensive.
Corrected Dall-Kirkham telescopes from Planewave are observatory-grade, ultra-premium telescopes.
The top models are then:
- The Takahashi FSQ-106 apochromatic refractor,
- The Planewave CDK17, and
- The Sky-Watcher Quattro 200/800 imaging newtonian
See the Best Telescopes for Deep Space Astrophotography for more insight into this area.
Sky-Watcher Leads for Telescope Mounts
For telescope mounts, Sky-Watcher is the most successful manufacturer by some distance:
The Sky-Watcher EQ6 Pro is the most used model, followed by the Software Bisque Paramount ME:
If we look at the last two years of data only though, we see that the Sky-Watcher EQ8 Pro has taken the top spot:
Models like the Hobym Traveller and iOptron CEM60/70 have also become more popular in recent years.
We can also break it down between what mounts for deep sky versus planetary imaging.
For deep sky, the Software Bisque Paramount ME is out front. This has a 240lb payload capacity and is for use as part of advanced setups.
The smaller Sky-Watcher mounts like the EQ6 Pro and NEQ6 Pro are also right up there. They are likely used with smaller apochromatic refractor telescopes:
For planetary imaging, Celestron mounts and larger Sky-Watcher mounts like the EQ8 Pro are more likely to be used.
They have higher payload capacities to deal with larger telescopes like the Schmidt-Cassegrains:
For more on this, see our article on the Best Telescope Mounts for Astrophotography.
The Sky-Watcher Star Adventurer is the Most Successful Star Tracker
For star trackers, the Sky-Watcher Star Adventurer is the most popular model:
Note though the two leading iOptron models taken together are used nearly as much.
See the Best Star Trackers for Astrophotography for more on this.
