We analyzed 685 images shortlisted for the Astronomy Photographer of the Year competition in the past five years to find the Best Planetary, Lunar and Solar Cameras.
We found that the ZWO ASI174 MM is the most successful planetary camera and is also top for solar and lunar imaging:
2.3 MP CMOS Monochrome Astronomy Camera
- Capture high-resolution monochrome images of the Moon, Sun, planets, and some deep-sky objects
- Advanced CMOS sensor with 1936 x 1216 (2.35MP) resolution
- Fast USB 3.0 transfer at up to 164 frames per second at maximum resolution, with higher data transfer rates at lower resolution
It has all the attributes of a great planetary camera:
- Fast frame rate (164fps at full resolution)
- Modest resolution (2.3-megapixels)
- USB 3.0 connection
The modest resolution and USB 3.0 connection are important because with planetary imaging you will take lots of short-exposure images and you need your laptop/computer to handle the volume of data.
This also means that it is relatively cheap (compared to high-resolution, cooled cameras for deep sky imaging) and this also contributes to its popularity.
Read on to see our full results analysis, to understand more about the differences between planetary cameras, and how to choose what is right for you.

Best Planetary Cameras (Data Analysis)
The Astronomy Photographer of the Year contest is the world’s most prestigious astrophotography competition. Every year hundreds of images are shortlisted and details of what cameras were used to take the photo are shared which we can examine.
We went through the results from the last five years (2018-2022), examining 685 images in total.
Of these, there have been a total of 193 planetary images shortlisted to look at (including planetary, lunar, and solar).
From this data, we can see that ZWO is by far the most successful brand for planetary cameras with 47% of all shortlisted planetary images using their models:
ZWO, Teledyne FLIR, and QHY make dedicated CMOS/CCD astronomy cameras. These are different from regular DSLR or mirrorless cameras in that they are specifically for astrophotography use with a telescope and can’t be used for regular, handheld photography.
However, the second, third, and fourth brands respectively are Canon, Nikon, and Sony, showing that planetary imaging can be done with conventional DSLR or mirrorless cameras.
In addition, Apple is on the list because of images taken with iPhones or iPads, showing that you can get results even with the most basic photography gear if you are creative.
Let’s now look at the most successful individual camera models.
Best Planetary Camera Models
In the chart at the top of this article, you can see the list of the most successfully used camera models for planetary imaging in this astrophotography competition.
Our results show that the ZWO ASI174MM is the top planetary camera:
This is an uncooled, monochrome CMOS camera that is tailored for planetary imaging.
It can be used for solar, lunar, and planetary photography. It can also be used for some deep-sky imaging, although it is not ideal for that.
What you need in a dedicated planetary camera is a fast frame rate, plus a modest resolution and USB 3.0 connection so that the data transfer to your laptop/computer can handle the volume of frames being taken.
This is the key difference with deep sky cameras that take fewer, longer exposures at higher resolutions, and need cooling to reduce noise.
Our results show that this camera delivers for planetary imaging and is relatively affordable so should make a great option for those looking for a good planetary camera.
With monochrome cameras, you need to use filters to take multiple captures to compose a color image.
The key specifications are:
- Type: CMOS
- Color/Mono: Monochrome
- Cooled/Uncooled: Uncooled
- Resolution: 2.3MP
- Frame Rate: 164fps (full resolution)
- Pixel Size: 5.86 microns
- USB: USB 3.0
There are two other uncooled, monochrome ZWO CMOS models in the top four of our results. We examine here the key differences between these three models.
ZWO ASI174MM vs ZWO ASI290MM vs ZWO ASI178MM
It’s notable that the first, second, and fourth most successful planetary cameras in our results are ZWO models.
In fact, they are all uncooled, monochrome CMOS ZWO cameras with USB 3.0. So what’s the difference between these three models?
- The ZWO ASI178MM has a higher resolution (6.4MP) and slower full resolution frame rate (60 fps) and smaller pixel size (2.4 microns). This means it occupies something of a middle-ground – being slightly less optimized specifically for planetary imaging, but slightly better for deep sky. It is also generally a bit cheaper than the ZWO ASI174MM, making it a great budget all-rounder.
- The ZWO ASI290MM is also cheaper and has a 2.1MP resolution and a full-resolution frame rate of 170 fps, making it very similar to the ZWO ASI174MM. It does have a smaller pixel size of 2.9 microns, but this a great budget planetary camera option.
So, in summary, the:
- ZWO ASI174MM performs best in our results for planetary cameras, but
- ZWO ASI178MM is great for those that also want to dabble in deep-sky imaging as well as planetary, and want a budget option, and
- ZWO ASI290MM is a great budget alternative specifically for planetary.

Best Color Planetary Cameras
The above models are all monochrome cameras. The advantage of these is that they can capture more detail in their images, but the downside is that to produce a full color photo you need to take multiple images using different filters and then combine them in post-processing.
This has the potential for better imaging results but is more work and complexity, as well as cost due to the additional filters and filter wheel that need to be used.
Color planetary cameras, on the other hand, can capture a full color image in one shot without the need to use external filters. They are therefore much easier to work with.
The top color planetary cameras in our results are all uncooled, color CMOS models from ZWO:
- ZWO ASI120MC – this is the cheapest and makes a great budget solar camera
- ZWO ASI178MC – this is the highest resolution option
- ZWO ASI224MC – this has a similar resolution to the ASI120MC but has a fast frame rate

Best Solar Imaging Cameras
When we look at the data for just solar imaging, we see that the Flir Grasshopper GS3-U3-23S6M-C camera is first, followed by the ZWO ASI174MM and ZWO ASI178MM (both covered above):
The FLIR Grasshopper GS3-U3-23S6M-C is an uncooled monochrome CMOS camera that has the Sony IMX174 sensor like the ZWO ASI174MM, and its key specifications are virtually identical:
- Type: CMOS
- Color/Mono: Monochrome
- Cooled/Uncooled: Uncooled
- Resolution: 2.3MP
- Frame Rate: 163fps (full resolution)
- Pixel Size: 5.86 microns
- USB: USB 3.0
It is substantially more expensive though, but our results show it delivers for solar imaging.
Best Lunar Imaging Camera
When we look at the best lunar imaging cameras, we see the ZWO ASI174MM first, followed by the ZWO ASI178MM, and the color ZWO ASI178MC:
FAQs
What are planetary cameras?
Planetary cameras are dedicated astronomy cameras for taking photos of the planets, sun, and moon of our solar system with a telescope.
Which camera is best for planets?
The ZWO ASI174MM is the best planetary camera, as indicated by our research.
How do I choose a camera for planetary imaging?
There are a few ways:
- You could use what you already have even if it is not the ideal planetary camera. For example, you can use a DSLR or mirrorless camera if you have one.
- You can use our findings to see what cameras are being successfully used by the best astrophotographers today
- You can use tools like this field of view calculator to input your telescope and prospective camera to see what images you could expect
Another thing to factor in is the other gear that you will be using. In particular, your telescope’s focal ratio and whether you will use a barlow lens.
There is a recommended formula for this:
- Barlow magnification x telescope focal ratio / 6 = approximate ideal camera pixel size
Therefore:
- A 3X barlow lens with a Celestron C11 F/10 OTA = 30. Divided by 6 = 5. Therefore a camera with around 5 microns pixel size is right. The ZWO ASI174MM would then be a good fit.
Since the most successful planetary telescopes are Celestron SCTs (see below) and these have F/10 focal ratios you can also work out what camera pixel size and barlow combination is right for you. For example:
- F/10 OTA with 2X Barlow = 3.3 microns
- F/10 OTA with 3X Barlow = 5 microns
- F/10 OTA with 4X Barlow = 6.7 microns
- F/10 OTA with 5X Barlow = 8.3 microns
These calculations should be taken as just a rough guide, as other things like the seeing conditions in your area are also a factor.
Other key characteristics to look for in a planetary camera are a high frame rate and fast USB 3.0 data transfer. Color vs monochrome is a choice: color is easiest, but monochrome has higher potential.
What telescopes are used for planetary imaging?
Our results show that planetary imaging is most commonly done with telescopes from:
- Celestron (45%)
- Sky-Watcher (19%)
The most successful models are Celestron’s Schmidt-Cassegrains.
For more insight, see the:
What telescope mounts are used for planetary imaging?
Our results show that planetary imaging is most commonly done with telescope mounts from Celestron (25%) and Sky-Watcher (29%) again.
The most successful model is the Sky-Watcher EQ6-R Pro.
For more on this, see our article on the Best Astrophotography Mounts.
What’s the best Celestron planetary camera?
The Celestron NexImage 10 is the best Celestron planetary camera.
It is the only model in Celestron’s NexImage range that has USB 3.0 for fast data transfer.
Planetary cameras vs DSLRs – what are the pros and cons?
Both DSLRs and dedicated astronomy cameras can be used for planetary imaging.
The advantage of DSLR (or mirrorless) cameras is their versatility which makes them suitable for all kinds of photography.
The advantage of a dedicated planetary camera is that it has been created specifically for that purpose and will be capable of a much higher standard of imaging.
What is the best camera for astrophotography?
The Canon EOS 6D is the best overall camera for astrophotography according to our research.
If you want to read more about this, see our article on the Best Cameras for Astrophotography.
What’s the best CCD planetary camera?
CCD cameras tend to be higher resolution and more suited to deep-sky imaging, with CMOS cameras being better suited to planetary imaging (as backed up by our research for this article).
To learn more about CCD cameras see our article, Best CCD and CMOS Cameras for Astrophotography.
Conclusion
Overall, based on our findings, we recommend the best planetary cameras to be:
- ZWO ASI174MM – overall winner for planetary, lunar, and solar.
- ZWO ASI290MM – a great budget alternative
- ZWO ASI178MM – a great option for those that also want to dabble in deep-sky imaging
These are all monochrome models. If you would prefer to go for a color camera, then we recommend:
- ZWO ASI120MC – best budget color planetary camera
- ZWO ASI178MC – highest resolution color planetary camera
- ZWO ASI224MC – fast frame rate color planetary camera
All this should be considered alongside what telescope you will be using to get the best results.
