“One of the most delightful experiences is to look into the sky through a Telescope!”
To add the cherry on the top, would not it be wonderful to capture such ravishing moments? Through the use of astrophotography, we can take pictures of the astounding celestial objects, observed through the lens of a telescope. If you are looking for telescopes, here are some Best telescopes under $300!
However, the obtained images are still in need of further processing to reduce unnecessary noise that diminishes the image quality. This is done by Stacking, which adds layers of similar images and averages them to form one resultant image. Stacking of Astrophotographs can be done with the help of Stacking software that are widely available. Some are available for free while others do come at a cost.
Considering which Stacking Software to go for? Worry no more, for in this comprehensive guide we have listed down the best astrophotography stacking software. Go through the article to know which one suits you the most!
Best Stacking Softwares for Astrophotography in 2022
The table below has a compiled list of some of the Astrophotography Stacking software that is considered the perfect ones out there. In the following sections, each one of them is explained in detail.
Sequator is one of the free astrophotography software that is present over the internet. It is used for stacking both – Deep Sky and Starry Landscapes. Not only it is commonly used as a Stacker, but can also be used to create star trails. It is an easy-to-learn and easy-to-use software, a very intuitive one. Moreover, Sequator is a fast system, therefore causing little to no hindrance while processing the images.
However, one major drawback is that it only works with Windows. Unfortunately, it is not an astrophotography stacking software for Mac but may be used on Linux via wine+. Furthermore, it is not as advanced as some of the other software mentioned in the article. Nonetheless, it possesses the ability to reduce noise, remove light pollution, and perform other simple tasks on stacked images. It can also calibrate light frames with dark and flat calibration frames. For a free astrophotography stacking software, it surely does provide enough!
2. Starry Landscape Stacker
Completely opposite to Sequator in the operating system support, Starry Landscape Stacker is an astrophotography stacking software for Mac OS X. It is not a free astrophotography software but a commercial software at $39.99. However, it is also somewhat similar to the Sequator for it is also a fast and easy-to-use stacking software for astrophotography.
Starry Landscape Stacker allows you to produce Landscape photographs captured at night time. It combines several images taken in rapid succession and shifts the sky to align the stars, in order to produce Landscape images. However, there is only one downside to it that it can not process your RAW format images. Hence, the images must first be converted to the more heavy TIFF format.
The disadvantage is can be overcome by the fact that Starry Landscape Stacker gives you a good quality image and the option to save the sky only for further editing in other software. In case you are genuinely interested in Starry Landscapes then this is the one for you!
No doubt, Adobe Photoshop always ends up in the list of the best astrophotography stacking software at present. It not only works as an astrophotography stacking software only but as a Complete Image Editor. It is compatible with Windows and Mac OS X. However, it is not free astrophotography software. It is a commercial one and is available at a subscription of $9.99/month.
Compared to many, Photoshop provides many more extra features when it comes to editing astrophotographs. It consists of many light-adjusting and noise reduction tools. Even though it has these extra features, you will have to download some extra Plugins first. Moreover, it also comes in a bundle with Adobe Lightroom CC, Camera Raw, Bridge, and Web Space. There is only the issue that Photoshop lacks the ability to calibrate light frames and in order to do so, some other software will be required.
4. Deep Sky Stacker
Deep Sky Stacker is considered the best stacking software for astrophotography. It is widely used to stack and calibrate images. The preprocessing steps are made easier with this software mainly due to the ability to stack all the images in one high-resolution file. The greatest part about DSS is the full calibration of images with Darks, Flats, Dark Flats, and Bias calibration frames to obtain the most suitable result possible.
It is to be noted that the DSS is believed to be the most amazing free astrophotography stacking software. Even though it lacks some noise reduction capabilities, it still has many more advanced stacking features. It is also a fast system making the user experience all the more enjoyable with its various features.
However, there are some limitations to the DSS. It is only Windows supported and therefore, not an astrophotography stacking software for Mac. Moreover, if you are looking specifically for Starry Landscapes or Planetary Astrophotography, DSS is not the right astrophotography stacking software.
5. Starry Sky Stacker
For Deep sky stacking on a Mac, Starry Sky Stacker is a good choice. It is a very basic and intuitive system to work with. The easy-to-use features and the fast processing of the system make it an ideal choice. It is a variant of the Starry Landscape Stacker for the purpose of deep-sky imaging.
The basic nature coupled with the absence of the ability to process RAW format images does not make it popular for high image editing. If you have one of the Best Mounts for Astrophotography your experience will be quite better.
6. Autostakkert!
If you are wondering about the best astrophotography stacking software especially for planetary motion, Autosatkkert! is the go-to option. It is an easy-to-use, free software, supported only by Windows. It is mostly used for Planetary, Lunar, Solar images, and for stacking full planetary disk and lunar surface close-ups.
The software is a little confusing to navigate through for a beginner, but it is relatively easy to go with the stacking steps. Although it lacks some of the features for planetary astrophotogra[hy, it is quite suitable for stacking planetary images.
7. Astro Pixel Processor
If you are in search of the best astrophotography stacking software without considering the cost of it, APP is the one!
At a subscription of $60/year on rent and $150 for an Owner’s License, it is one of the best Deep Sky Astrophotography Editors present nowadays. However, there is an added benefit of a free 30-day trial period for you to get yourself acquainted with it. Not only does it possess plenty of advanced features, but it also has compatibility with the three most commonly used operating systems – Windows, Mac OS X, and Linux. Moreover, it is rather easy to use.
Some of the advancements are in calibration, stacking, and post-processing of deep-sky images. It is, however, held back with the fact that it is only suitable for deep sky astrophotography.
Lynkeos is the astrophotography stacking software for Mac. It is mainly for planetary stacking and is free of cost! Most importantly it is the only free planetary stacking software for Mac. Image stacking software for astrophotography for Mac users are in lesser amounts and those that are there are usually costly.
The software is quite an intuitive one but it becomes a little less easy while performing different functions. However, it has deconvolution and wavelet sharpening technology, which are necessary for Planetary Stacking.
9. PixInsight
PixInsight can be considered to be the best astronomy software. It is an all-rounder Astrophotography editor and a commercial one available for $273.88. Although it is expensive software, it provides you with a lot to make it worth the price. It is inarguably the greatest stacking software for Astrophotography!
To start off, it provides a 45 days trial period to let you make yourself comfortable with it. It comes with various tutorials and information. With all those great things, it has a steep learning curve. Moreover, the user experience is a tricky one. Not only this, it requires to be run on a recent and powerful system.
10. SiriL
SiriL can be considered to be the best free astrophotography stacking software. Not only it has many features but it is also cross-platform. It can run on three operating systems – Windows, Mac OS X, and Linux. It is not as easy or intuitive as some of the other free software already mentioned, but it is worth the try for it has extra added features.
It helps you to develop deep sky images, calibrate, and stack astrophotography images. This image stacking software for astrophotography has the ability to produce good quality images due to the presence of many options. It also has the ability for image post-processing.
Exposure Stacking Software
Exposure Stacking Astrophotography is the term used to mean the same thing as Star Stacking. Star Stacking is simply a method of overlaying multiple night-sky exposures and then averaging them up to get an image with reduced noise.

Conclusion
In this article, we have compiled the list of the best image stacking software for astrophotography. The list is quite diverse in nature for it provides you with a range of amazing astronomy software, to specific Planetary stacking, or Deep-Sky image stacking astrophotography software. Out of all those mentioned, no doubt PixInsight is the best stacking software for Astrophotography!
Stacking software for astrophotography exists many at present but not all of them fulfill the requirements completely. Most importantly, Astrophotography software for Mac is less, especially free ones, but those are worth the money and effort and mentioned in detail. Astrophotography stacking software Mac is mostly nature-specific like Starry Landscape Stacker or Starry Sky Stacker.
Photo stacking astrophotography is an art in itself, and to know about more of the stacking programs for astrophotography, here is another article for your convenience.
To capture astrophotography images, you will need a Telescope, of course! To learn how to make your own telescope, do read How To Make a Telescope With Two Convex Lenses. Moreover, you can also check out our reviews on different telescopes!

For a successful processing session, I recommend stacking a minimum of 10-12 exposures. In this example, each individual exposure was shot at ISO 3200, and were 30 seconds each. This is a typical exposure length and ISO for any night photography image.
Starry Landscape Stacker does a pretty good job by itself. If you only plan to stack a dozen or so deep-sky images, then I don't see a need for the upgrade. Starry Landscape Stacker also supports Light, Dark, Flat and Bias frames, so it can handle more than you think.
The concept of stacking in astrophotography is simple, by combining multiple images together, the signal-to-noise ratio can improve. With so much time and effort going into the acquisition stages of astrophotography, it would be a shame not to achieve the best possible results when stacking your images.
In astrophotography, stacking, also known as integration, is all about increasing the signal-to-noise ratio (SNR) of your images; in other words, increasing the signal that you do want and reducing the noise you don't.
Star stacking requires capturing multiple shots at the same shutter speed so that they can be aligned and averaged later. The more shots you have, the less noisy the star stacked result will be, but only up to a point before sensor pattern noise starts being visible, or you completely exhaust the signal to noise ratio.
A free trial version of Starry Sky Stacker is available. It is identical to Starry Sky Stacker except it watermarks the output image and it has a "Buy" button in the tool bar. Feel free to download it and use it as you wish.
The final step to do with Siril is to stack the images. Go to the "stacking" tab, indicate if you want to stack all images, only selected images or the best images regarding the value of FWHM previously computed. Siril proposes several algorithms for stacking computation.
To install StarStaX, extract the .zip archive and double-click on “StarStaX.exe” in the folder StarStaX-0.71. There is no installer. You can manually copy the StarStaX folder to any folder you like and create a link to StarStaX.exe, e.g. on the desktop or in the program menu.
We offer free trial software licenses that you can use to evaluate a fully-functional, full featured trial version of PixInsight on any supported platform. We stand behind our software. We provide support and updates at no additional cost (included with all commercial licenses).
Focus stacking software is ideal for combining different images in order to create a sharp photo. They are also called photo stacking software because the effect is achieved by superimposing the images. The best focus stacking software on our list comes from Adobe, a great tool for advanced users.
It usually takes some time for Photoshop to create a single Smart Object from all of the exposures. Next, go to the menu Layer → Smart Objects → Stack Mode → Mean. Doing so makes Photoshop automatically blend the images in the stack into a smooth, long-exposure.
Stacking your images in Photoshop has several benefits. First, stacking gives you the ability to produce ultra-high resolution megapixel monsters such as this 100 megapixel image that photographer Michael Ver Sprill produced: The technique involves allowing the camera to move slightly in between shots.
So the signal-to-noise ratio is 100/10 = 10. If we collect 10,000 photons, the noise is 100 (100 is the square root of 10,000), and the signal-to-noise ratio is now 10,000/100 = 100. This higher signal-to-noise ratio will produce a much better image even though, technically, it has more noise.
Typical setup for untracked astrophotography; instrument requirements are minimal. All you need is a DSLR, a tripod and a remote release timer. You may want to add a lens hood and a right-angle viewfinder. Capture noise-free images of star clusters, nebulae and the Milky Way without any tracking device.
The Full Width Half Maximum (FWHM) is a measure of the quality of an astronomical image based on how much the telescope and atmosphere have smeared a point source in an image over several pixels in the CCD.
The DeepSkyStacker help sections states that using a minimum of 20 frames is ideal, and using 50 – 100 will create nearly noise-free master dark frames. If you have the time and to take 20+ dark frames, it's a good idea. Just aim to use at least 15 as a minimum.
DeepSkyStacker is a useful piece of freeware that allows you to register (align) and stack multiple images into a single frame, revealing detail that is difficult to capture otherwise. For astrophotography, this means you can make use of short exposure images for captures of deep-sky objects.
Select the layers in the group and choose Edit > Auto-Blend Layers. In the dialog that appears, select Stack Images and (optionally) turn off Content Aware Fill Transparent Areas. Click OK. Photoshop then creates a layer mask for each layer that allows the sharpest areas to remain visible.
Lightroom Classic can automatically stack photos in a folder or a collection based on their capture time. You specify a duration between capture times to create a new stack.
To group the exposure-bracketed images and the HDR image in to a stack (after the images are merged), select the Create Stack option. The merged HDR image will be displayed at the top of the stack. Click Merge to create the HDR image (. dng).
Use File -Scripts -Load Files Into Stack. When doing this tick both "Attempt to Automatically Align Source images" and "Create Smart object after Loading Layers"
Select the Smart object.
Go to Layer - Smart Objects - Stack Mode - Median.
Select the Edit menu and then hover over Stack. There are two options available. We'll look at the option to stack automatically at another time. To manually stack the photos using the ones you've already selected click Stack Selected Photos.
What is SharpCap? SharpCap is an easy-to-use and powerful astronomy camera capture tool. It can be used with dedicated astronomy cameras, webcams and USB frame grabbers.
PICOLAY is a tool for generating improved images from picture series on Windows(TM) computers. The program has been written by Heribert Cypionka and can be used freely for non-commercial purposes. The program is offered 'as is' without any warranty.
Click on the Sequences tab, then choose the sequence of the preprocessed flats (normally, it is already loaded at this stage). Click on the Stacking tab. Set the parameters as above. Click on Start stacking .
Star trails reflect Earth's rotation, or spin, around its axis. The Earth makes a complete rotation relative to the backdrop stars in a period of about 23 hours and 56 minutes.
Star stacking requires capturing multiple shots at the same shutter speed so that they can be aligned and averaged later. The more shots you have, the less noisy the star stacked result will be, but only up to a point before sensor pattern noise starts being visible, or you completely exhaust the signal to noise ratio.
Stacking your images in Photoshop has several benefits. First, stacking gives you the ability to produce ultra-high resolution megapixel monsters such as this 100 megapixel image that photographer Michael Ver Sprill produced: The technique involves allowing the camera to move slightly in between shots.
One of the best benefits about stacking multiple exposures is the dramatic increase in the image quality, noise removal, by increasing your signal:noise ratio. When you stack, you reduce the differences in the digital representation of the light that hits and excites the camera sensor.
Select all of the Sky layers again, right-click on any layer, and choose “Convert to Smart Object”. Once that's processed, then all that's left is the final step of blending them all together. Again, with the layer selected, head up to “Layer > Smart Objects > Stack Mode > Median”.
Select the layers in the group and choose Edit > Auto-Blend Layers. In the dialog that appears, select Stack Images and (optionally) turn off Content Aware Fill Transparent Areas. Click OK. Photoshop then creates a layer mask for each layer that allows the sharpest areas to remain visible.
It usually takes some time for Photoshop to create a single Smart Object from all of the exposures. Next, go to the menu Layer → Smart Objects → Stack Mode → Mean. Doing so makes Photoshop automatically blend the images in the stack into a smooth, long-exposure.
The best way to get high-resolution images is by using the right camera for the job. But when that's not an option — or you're looking to improve older digital photos — Adobe Photoshop and Adobe Photoshop Lightroom can help. Experiment with Super Resolution and resampling to see how far you can push your image quality.
Focus stacking allows the depth of field of images taken at the sharpest aperture to be effectively increased. The images at right illustrate the increase in DOF that can be achieved by combining multiple exposures.
Stacking is definitely worth it on lunar images shot with a DSLR. Regardless how good your camera, equipment or technique is, you can't match the results of a stacked image in a single frame.
PIPP is a Windows application designed for pre-processing planetary images before stacking them with image stacking software such as Registax. PIPP's main purpose is to crop each image frame and select only the best quality frames to reduce the memory and processing requirements of the stacking software.
Focus on the object closest to the lens and take an image. Adjust the focus to be further away (how much depends on the distance between the foreground and background) and take another shot. Repeat step number 4 until you've got enough images to make the entire image sharp.
You can even stack JPEG images to improve the signal-to-noise ratio, although this is not recommended either. As with light frames, you get better results if you have a series of calibration frames that can also be stacked to improve their signal-to-noise ratio.
