In astrophotography you cannot avoid post processing your images, so stacking and editing your images serves three main purposes:
- Reduce noise and deal with light gradients and vignetting.
- Improve signal to noise ratio.
- Reveal the faint details in the image.
Image stacking is the technique used to improve the signal to noise ratio, and it is the only noise reduction method that will boost the image details rather than smear them out.
In this article, we will discuss some of the most popular software available for astrophotography image stacking.
Note: Don’t miss the detailed video at the end of this article, It was created to help show you how to quickly start using some of the stacking software mentioned in this article.

What Does Stacking Photos Mean?
The concept behind image stacking is simple, but to appreciate how it works, there are a couple of things we have to consider:
- A stack can be visualized as a pile of images all stacked one on top of the other;
- Each digital image is formed by a set of pixels, all having a certain value: dark pixels will have a lower value than the bright ones;
In the simplest form of image stacking, the pixels values for all images in the stack are averaged to produce a single image.
What is the purpose of stacking photos?
The result is a single image with improved signal to noise ratio, i.e., with better details and lower (random) digital noise and better details.
The scheme below illustrates the concept.
If the considered digital noise affects the pixel values randomly across the stack, then the result of averaging the stack is that the random component of the noise to the pixel value is significantly reduced.
ISO noise and Luminance noise and Chrominancenoise are examples of digital noises that are random.
The image below shows a real-life example from stacking 30 images from my Sony RX10 bridge camera taken at ISO 6400. As you can see, the original images showed a greater deal of noise (grain) than the stacked one.
The More Images You Stack, The Better
The more images you stack, the cleaner the resulting images are, as shown in the comparison below.
While Image stacking creates a cleaner image, it often softens the image: digital sharpening techniques are then used to recover sharp looking details.
Finally, bear in mind that the progression of image quality is not linear.
If stacking 4 images improves the image quality of 50% respect what you got by stacking only 2 images, to improve a further 50% the image quality from stacking 50 images, you may need to stack 300 images or more.
Image Stacking And Movement
If nothing moves between shots, like in the previous real life example, implementing image stacking is very simple: just group the images and average them to smooth out the noise.
With a moving subject, grouping and averaging the images will not only smooth out the noise, but also the subject itself.
This is the same principle for which long exposures of passing traffic and crowd result in a street image without cars nor people.
This effect is amplified with the number of images used, and the moving subject could simply disappear from the stacked image.
To resolve the issue, you have to align the images based on their content before stacking.
Due to image alignment, you may have to trim the edges of the stacked image to get rid of artifacts, but your target will not be lost.
Note that while in theory you can stack images of a static scene taken with the camera on a tripod, in reality, those images will probably differ at the pixel scale due to micro-movements. It is always beneficial to align the images before stacking.
How To Shoot For Exposure Stacking Your Images
Image stacking can be done with any camera and even camera phones and with images in both RAW and JPEG format.
Nonetheless, some things can be done to improve the final result:
- Lock the focus, so that the camera will not hunt for it between images. This will also help to keep the focus consistent through the shooting sequence.
- Keep the same settings, in particular shutter speed, aperture, and focal length: you don’t want to change the camera field of view during the sequence, nor the brightness of the images or the depth of field.
- If you are shooting on a tripod, disable image stabilization. If you want to shoot handheld, do so only for short sequences at very high shutter speed.
Image Stacking In Astrophotography

As said previously, image stacking is a standard technique implemented in any astrophotography editing workflow for,
- A star field from a fixed tripod.
- A deep sky object from a tracking mount.
- The Moon handheld.
- A starry landscape from a fixed tripod or tracking mount.
Every astronomy image will benefit from image stacking.
List Of Photo Stacking Software For Astrophotography
Here is a list of software used in astrophotography for image stacking.
Adobe Photoshop
Complete Image Editor | Commercial – Subscription Plan Photography Bundle $9.99 / Month | Mac OS X, Windows
Pro
- Versatile
- Available for Mac and Windows
- In bundle with Adobe Lightroom CC, Bridge, Camera Raw, and web space
- Many action packs and plugins available for astrophotography
Cons
- Subscription Plan only
- Can’t be used to calibrate light frames
- Stacking capabilities are somehow limited
If you are interested in photography, chances are you know Adobe Photoshop is the standard in the industry and does not need introductions.
With Adobe implementing a subscription plan for their applications, if you are using Lightroom CC for your everyday photography, your plan subscription will also include Photoshop CC and Bridge CC.
And for astrophotography, Photoshop is what you need. Lightroom cannot stack your images nor perform the histogram stretching, two crucial steps in the editing workflow for astrophotography.
In this article, we have already covered in detail how to stack astrophotography images with Photoshop.
Sequator
Deep Sky And Starry Landscape Stacker | Freeware | Windows
Pro
- Free
- Easy to use
- Fast
- Suitable for both Starry Landscapes and Deep Sky images
- Can create Star Trails
Cons
- Windows only
- Limited set of options
- Not suitable for Planetary astrophotography
Sequator is an easy-to-use and intuitive astrophotography software for stacking both starry landscape and deep-sky images. It can also be used to create star trails.
While not as advanced as other stackers, it nonetheless allows you to calibrate your light frames with dark and flat calibration frames. It also allows you to remove light pollution, reduce noise, and perform other simple tasks on the stacked image.
Starry Landscape Stacker
Starry Landscape Stacker | Commercial, $39.99 | Mac OS X
Pro
- Fast
- Easy to use
Cons
- Mac Os X only
- Does not read RAW files
If you are into starry landscapes and you are a Mac user, Starry Landscape Stacker is a must-have.
Easy to use, it allows you to stack and align the sky and the foreground independently by letting you easily mask the sky.
Unfortunately, the software lacks the support for RAW formats, thus forcing you to convert your RAW images in the more heavy TIFF format.
Aside from that, it works very fast and the final image is of good quality. You can also save the sky only, which is useful to further edit the shot in Photoshop or similar editors.
Starry Sky Stacker
Deep Sky Stacker | Commercial, $24.99 | Mac OS X
Pro
- Fast
- Easy to use
Cons
- Mac Os X only
- Does not read RAW files
- Basic
Starry Sky Stacker is Starry Landscape Stacker brother and it has been created to stack deep sky astrophotography images.
As Starry Landscape Stacker, Starry Sky Stacker is very easy to use and intuitive, although very basic.
If you are a casual star shooter and a Mac user, this could be a good choice for you.
Deep Sky Stacker
Deep Sky Stacker | Freeware | Windows
Pro
- Free
- Easy to use
- Fast
- Full light frames calibration
- Features Comet stack modes
- Can Drizzle
- Many advanced stack options and methods available
Cons
- Windows only
- Post-processing is quite limited
- Not suitable for Starry Landscapes nor for Planetary astrophotography
Deep Sky Stacker, better known as DSS, is arguably one of the most widely used software to calibrate and stack astrophotography images.
With DSS, you can fully calibrate your images with Darks, Flats, Dark Flats, and Bias calibration frames for the best results possible. Light frames are analyzed and scored by quality so that you can decide which percentage of best images you can stack (Best 75% by default).
A very interesting feature is that with DSS, you can easily combine images taken during different imaging sessions, to produce images of higher quality.
Autostakkert!
Planetary Stacker | Freeware | Windows
Pro
- Free
- Easy to use
- Suitable for Planetary, Lunar and Solar images
- Stack full planetary disk and lunar surface close-ups
Cons
- Interface a bit confused
- It does not offer wavelet sharpening
- Windows only
Autostakkert!, also known as AS!, is a very popular free software among the solar system astrophotographers. With AS! it is easy to stack both images showing the full Planetary (or Lunar or Solar) disc and images showing lunar surface close-ups.
The interface is a bit confusing, particularly in the beginning, but it is easy to navigate through the different steps for the stacking.
Unfortunately, AS! does not offer wavelet sharpening, which is a widely used technique in planetary and lunar astrophotography. For this, you can load your stacked image in Registax, another freeware software for Windows only that, sadly, is now “abandoned-ware.”
Lynkeos
Planetary Stacker | Freeware | Mac OS X
Pro
- Free
- Has deconvolution and wavelet sharpening
- It is probably the only freeware planetary stacker for Mac OS X
Cons
- Not very intuitive
- Somewhat slower than Autostakkert!
Lynkeos is perhaps the only freeware planetary stacker software for Mac OS X, sparing you from turning to Windows for using Autostakkert!.
The interface is quite intuitive to navigate, but not when it comes to performing the different tasks.
On the other hand, it offers a deconvolution method and wavelet sharpening, a must-have for a planetary stacker. Definitely worth having a look at it if you are a Mac user.
SiriL
Deep Sky Astrophotography Editor | Freeware | Mac OS X, Windows, Linux
Pro
- Free
- Cross-Platform
- Active development
Cons
- A bit convoluted and not as intuitive as other stackers
SiriL is a freeware, cross-platform, astrophotography package that will let you calibrate, stack, and develop deep sky astrophotography images.
While not as easy and intuitive as Sequator or DSS, it offers a lot of options and produces good results. There is an active community, and it is under constant development.
Astro Pixel Processor
Deep Sky Astrophotography Editor | Commercial $60/Yr Renter License Or $150 Owner License | Mac OS X, Windows, Linux
Pro
- Full-grown astrophotography package
- Fairly easy to use
- Mosaics are created with ease and are of great quality
- Active and constant development
- Cross-Platform
- 30-days Trial period
- Affordable yearly subscription
Cons
- Only for deep sky astrophotography
- No Comet stacking mode
With Astro Pixel Processor (APP), you step in the realm of full-grown astrophotography packages, with many advanced options and methods to calibrate, stack, and post-process your deep-sky images.
Compared to PixInsight (PI), the software benchmark for the category, APP is cheaper and way easier to use, which makes it one of the best PI alternatives.
If you decide to buy it, you can choose between the renter’s license for $60/yr, to always get the latest version of APP, or the owner’s license for $150, but you will have to purchase the license again for major update releases.
PixInsight
Astrophotography Editor | Commercial – €230+VAT | Mac OS X, Windows, Linux
Pro
- It has all you need for astrophotography
- 45 days trial period
- A lot of tutorials and information available
Cons
- Expensive and without subscription plan
- Extremely steep learning curve
- Long and convoluted process
- Needs a powerful computer
When it comes to astrophotography, PixInsight is the software of reference against which all others are measured. It offers everything you may possibly need to produce pro graded images, and it is objectively the best software in the field.
But user experience can be frustrating, as the learning curve is very steep, the editing is long and convoluted, and your computer must be quite recent and powerful to make it run smoothly.
The €230 + VAT price tag is also quite steep: sure it is worth every penny, but this makes PI be even more the software of choice for professional and keen amateur astrophotographers.
A Comprehensive Demo About Image Stacking
In this video, I show you how easy it is to wet our feet with image stacking.
This is particularly true if you use Starry Landscape Stacker, Sequator, Deep Sky Stacker and Autostakkert!, as I showed in the video below.
Conclusion
Image stacking is one of the crucial steps in the astrophotography editing workflow.
You’ll need the appropriate stacker for each type of astrophotography: starry landscapes, star trails, or deep-sky and planetary images.
In this article, we have covered the most popular astrophotography stackers available on the market, both freeware and commercial.

10.12 is available again, and the above tip on 10.12-10.14 covers how to get it.
Some people who no longer need it, may be able to transfer their license to someone who does. Snow Leopard is available for pre-March 15, 2010 Macs that are compatible with it. Apple minimum hardware requirements are the same for 10.8, 10.9, 10.10. and 10.11. 10.13 high Sierra is available: High Sierra upgrading tip
Apple's original Mavericks system requirements are archived here:
Before updating to 10.7 or later from 10.6.8 or earlier, please read this tip as a lot of software that is compatible with 10.6.8 and earlier is not with 10.7 and later, making the 'free' update to 10.9 and 10.10 not so free:
Some prebundled 10.9 Macs can be upgraded to 10.12 then to Catalina.
Yosemite was released October 16, 2014 and has the same minimum system requirements and Mavericks. Only download or install Yosemite compatible software said to be Yosemite compatible as of reports after that date.
Note: 10.9.2 fixes a critical security flawin earlier versions of 10.9. Airplay appears to be problematic with 10.9.2. The reason behind
it is not known. If you have a pre-10.9 machine, ask on the forum how to safely downgrade to a previous version of 10.8.5 or earlier which is safer than 10.9 or 10.9.1 if Airplay is critical. It is not yet known if 10.9.3 or 10.9.4 fixes the Airplay issue. This issue will be updated on: https://discussions.apple.com/docs/DOC-6831
A new solution for Airplay is on the link, as of April 6, 2014, regarding Bluetooth conflict.

Mavericks has the same hardware requirements from Apple as Mountain Lion, Mac OS X 10.8, which I outline here
See this tip to find your Mac model's age:
Like always, you must backup your data before installation as I describe here
And since there are more programs, which are listed on http://www.apple.com/osx/specs/
there is a chance some software that works in Mountain Lion may not work in Mavericks.
https://itunes.apple.com/us/app/os-x-mavericks/was the direct download link from the U.S. You will want to contact if you have interface or compatibility issues that need to be addressed by Yosemite before downloading Yosemite first to see if an exception can be made to get Mavericks instead:

Caution: the Apple Launchpad App if edited in prior operating systems by third party applications may lose its icons.
Some third party USB 3 cards are not compatible with the installer for Mavericks, and may make external drives disappear,

and some external drives might disappear as well, if their firmware is not updated and connected while the installer does
its installation. Dismount, and disconnect all external drives prior to installation.
Western Digital hard drives that use software from Western Digital may lose data when upgrading to Mavericks. This tip has been
written to discuss the issue.
Third party devices that require sync services such as Markspace's based software will likely not sync until said software has been updated for 10.9.
The Launchpad in the Dock will show you the download file size progress for downloading the App from the App Store if you hover your mouse pointer over it.
Note, this progress is only for the download. The progress for the actual installation is not always apparently precise. It may tell you it is 1 minute from completing one portion of the install, but in reality be over an hour. Once downloaded, it took me two hours to install the operating system on an iMac 11,1 that already had 10.8.5 loaded.
10.9 when it is done loading the file from the App Store, will put a 5.31GB file called 'Install OS X Mavericks.app' (without quotes) in your hard drive -> Applications folder.
5.31 GB works out to be approximately 45 billion bits, which at 7 Mbps would take 6400 seconds or 106 minutes, or 1 hour 46 minutes.
If you are running a program in the foreground when the download takes place, it will put the installer screen behind your other windows. Quit all open applications before running the actual installer.
It became available October 22nd, 2013. Macs that are newly released by Apple on the same date or later may not be able to run Mountain Lion or earlier, but should still be able to run earlier versions of Linux and Windows in virtualization the same as Mountain Lion.
Most issues can be resolved if you clone backed up your previous operating system before installinf Mavericks, unless there was some underlying issue not diagnosed before the upgrade.
Canon has made some new printer drivers: http://support.apple.com/kb/dl899

iTunes 10.6.3 was tested by me on Mavericks, and the purchased music would not play, nor authenticate. It is the last version of iTunes I'm aware has coverflow.
Like there is for 10.7 and 10.8, http://roaringapps.com/apps?platform=osx
offers a third party table for software compatibility. Ignore the El Capitan compatibility, as that has not been released yet.
However, once again RoaringApps has taken it upon itself to show compatibility of a not finalized operating system upgrade. In this case of Yosemite.
As Apple could change features before final release, take such compatibility reports for Yosemite with a grain of salt, and ensure that once it is released that the reports are dated after Yosemite's final release.
iTunes/Mac OS/iOS compatibility discusses solutions for people still running 10.9.5 who wish to downgrade to iOS 10 and link their iOS device to their Mac. With iOS 12 already released it pushes the minimum Mac OS X system requirements to 10.11.6 for many.

10.14 Mojave is available to all Macs that shipped new with 10.9 except the MacBook that had no Air or Pro moniker.
That model had to have shipped with 10.10 Yosemite to be able to upgrade to 10.14. And upgrading it to 10.12 first was necessary to get it to Mojave.
