What’s ASIStudio?
ASIStudio is an astronomy software package developed by ZWO, which currently including ASICap, ASIImg and ASILive.
- ASICap——specialized in planetary imaging, with an earlier release date, has experienced multiple iterations and gains a lot of popularity.
- ASIImg —— specialized in DSO imaging for desktop platform, is a great attempt to create a software by our years’ experience on development.
- ASILive—— specialized in live stacking. The first beta version was released at Nov 2019, is a strong competitor in live stacking software, also get many good reputations.
With this software, the future of ASIStudio is quite clear: ASIStudio will be a unified software package including all the imaging and post-processing work. Combined with popular ASI camera, a full-featured ecosystem for astrophotography will be built.
You don’t need to learn other complexity software, ASIStudio will be enough for you.
ASICap
ASICap is the first software in this collection, can be used for planetary, solar and lunar imaging. The UI is quite straightforward, you could easily adjust parameters, such as resolution, exposure time and gain. The software won’t let you miss a single clear night to take images.
ASIImg
ASIImg is the latest software in this collection. Currently could be used for DSO imaging with/without scheduled task. We plan to add sky chart, assist polar align, focusing and plate-solving in future versions in this year. Ultimately, it’s gonna meet all the demands for DSO imaging.
The development progress of ASIImg is steady, thanks to the experience for developing ASIAIR.
ASILive
ASILive is focused on live stacking. You could see the image stacked in real time with stretch and denoise automatically. A no-brainer experience for imaging.
Surprisingly, due to the convenient and easy to use of the software, ASILive has drawed attention from the fans of EAA.
Live stacking, 2 frames stacked
Live stacking, 109 frames stacked
What can ASIStudio bring us:
As a newborn software platform, ASIStudio is far from its ultimate goal. There are already many mature software, such as FireCapture, SharpCap, Maxim DL and NINA. You will be impressed if you are specializing some of these software.
But ASIStudio has its own advantages:
1.Completely complimentary
Like earlier software developed by ZWO, ASIStudio is also complimentary. You can download the software from any appropriate platform. Although ASIStudio only supports ASI camera, but we think most astronomy amateurs have at least one ASI camera. So, it is not a disadvantage.
2.Better support for ASI cameras
ASIStudio will be more robust because we focused on support our own cameras.
3.Easier learning curve
There are all kinds of astronomy imaging software, but most have a quite steep learning curve. ASIStudio is more user friendly because it has a simple, intuitive UI and more convenient operations.
4.More specialized software
Instead of integrating planetary/Solar/Lunar imaging, DSO imaging and Live stacking in one software, ASIStudio separates them into 3 individuals which can run independently: ASICap, ASIImg and ASILive. Some new features are under development, such as FITS viewer, will also been added as a gadget. This means you don’t need to download the entire software package for just a single feature (For example, purchase and download Maxim DL to view a FITS file). More flexibility for customers to imaging and post-processing.
5.Cross platform support
ASIStudio currently supports Windows 32-bit/64-bit, macOS, Linux (64-bit only). A great news for Linux and macOS customers.
The future of ASIStudio
ASIStudio is a long-term software project for desktop platform. We will keep shaping the software and add more features over time. We also keep a close eye on other great astronomy software, we may integrate it into our package after received their authorizations.
ASIStudio will become a full-featured, one-stop astrophotography software package, including the software developed by ourselves, gadgets and authorized third party software. ASIStudio will become the best solution for astronomy amateurs. We will make the astrophotography easier than never before.
When we start developing ASIStudio, someone told to us, we will never catch up the pace with software like SharpCap. Even some of our competitors stop developing similar software, as they think it is a totally waste of time. We know we have a vast gap from mature software, but it’s just a beginning.
As proven said: “Rome wasn’t built in a day”. A software project cannot become perfect from in a short time. We will never catch up the pace with others if we afraid of facing the failure. ZWO is working hard on astrophotography for 8 years, we will never give up.
We value your opinion!

After downloading ASIstudio I was very pleased and surprised by the ease and functionality of the software. As a user of several of the popular imaging and stacking systems this one validates my skills as a deep sky imager and takes much of the work out of getting really good images. As I have read that you plan to integrate a star chart and other features that only work with AS I cameras is not a disadvantage. In fact it is a plus and thus far ZWO is a proven leader in this field of work/hobby. Keep up the great work.
Moson
Thank you for supporting us,we are glad you like our ASIStudio.
Travis
Just started using ASI Studio Wow I like it easy and simple to use this is how it should be done!!! Love the vision I’m on board my next purchases are all ZWO products EAF and ASIair pro wish I could buy now waiting on next bunch to get shipped I guess hard to get the pro sold out every where…
Moson
Thank you for your love and support for our products.We will speed up production and provide sufficient supply for each customer.You can order it as soon as possiblle, and usually we arrange the orders by the time we receive them.
Travis
Ok I ordered today super excited to get my ASI pro ASAP till then I will keep learning ASIStudio is their any tutorial videos I can watch while I’m waiting to learn more on operating the system?
Moson
I’m sorry we don’t have tutorial videos for ASIStudio.If you have any feedback and suggestions, please tell us via Facebook Messenger or E-mails.

Email is preferable what’s the email I should contact
Moson
You can ask any questins here, if you need some technical support, you can send an e-mail to support@zwoptical.com.
Sergey
Hi! Will it work in conjunction with ASIAIR pro for EAA purposes? (I.e., remote control and live stacking)
Moson
ASIStudio is a computer software, which is different with ASIAIR pro. You can use ASIAIR in your mobilephone or tablet. And the ASIStudio can do live stacking for EAA.
Eyal
I’ve installed the SW but when opening ASIImg i get error not enough disk memory.
i don’t have such error with ASICAp and ASILive
Moson
We have fixed this problem and will release a new version soon.
Ricardo
Hello,
I am totally new to this astro game. Today I will take receipt of 2 asi cameras.
I have downloaded the asi studio software and have been looking through it.
I have great difficulty reading the red on the black. I know why its red, but wonder can it be changed within the program to a different contrast. At present my eyes cannot read it.
Thanks
Rikki
Moson
You could click the skin button on the left of the setting button on the main interface. And then choose another color.
Martin
Hi,
the new ASILive works very well and I’m very happy with it but the live stacked result is sometimes too greenish in my light polluted environment. How can I adjust the color in this tool?
Thanks Martin
Moson
Sorry the ASILive adjust the color automatically, could you take a screenshot for us to see how it comes greenish?
You could send the screenshot to us by link or send to support@zwoptical.com.
Martin
You can see it in our last Livestream from our Observatory:
https://www.facebook.com/Sternwarte.Radebeul/videos/264082138085378/
e.g. 1:40; 2:02, 2:23; 2:30,
Moson
It’s normal. You don’t have to worry about this, you could adjust the color in the post-processing software.
Chris
I’m enjoying ASI Studio a lot. Very elegant design.
Is it possible to autoguide in the Deep Sky and Stacking modes? I only see the guiding icon in the ASIcap mode.
P.S. I have my 183MC and my 290mini. Now, when is that ASIair Pro going to arrive (ordered April 1)…?
Moson
Sorry it can’t autoguide in the Deep Sky and Stacking modes at present. We still need third party guiding software. But our devs are considering to put this feature in ASIStudio.
Could you tell me where did you buy the AIR PRO? And the order number? We will arrange the delivers as soon as possible.
Chris
Hi-
Thanks for responding!
I purchased my ASIAIR PRO from High Point Scientific (yes, April 1). My order # was 1000159643. Any assistance you could offer would be great.
Thank you!
Moson
The High Point Scientific has a few inventory, you could contact HPC directly for details.
kippauls
I like to format of ASIStudio. I see there is live stacking. So will there be image stacking post processing for planetary images in the future like autostakkert and Registax? They haven’t been updated in a long time.
Moson
Thanks for supporting! But it’s hardly to stack planetary images currently. I will convey your feedback to our devs and they will consider this.
Erwin Seyssens
When I use de deep sky mode (img) it says the cooler is off. In Asicap (planetary) mode, I can switch on the cooler ON and set the temperature. In DSO mode there is a setting for temperature, but the cooler is OFF? Any method to have the cooler ON in deep sky mode?
Thanks!
Love ASI cameras!
Moson
Could you please tell us how you operate your camera and ASIStudio?
And please send a screenshot of your setting to us.
Robert R
One feature I noticed in SharpCap is the ability for the histogram to include only a portion of the image. Is this option considered for Studio or ASIAir? Even histograms of several areas might be useful. It’s the first I’ve heard of this feature, but it seems to me that it could be very useful. I’m interested in others thoughts.
Moson
There is a ROI feature on ASIStudio, it means you could choose an area of the image and see the histogram of this area.
Dan
Where is this ROI feature. I only find resolution change drop list.
ZWO.Moson
You can use the right mouse button to pull out a selection box on the screen to enter the ROI feature.
Stefano
Just wondering…. there’s no manual for ASICAP or ASISTUDIO either? I have just bought an ASI mini camera and the quick guide says I should find a manual for the imaging software somewhere…
Thank you
Moson
Sorry we currently don’t have manual. And we will produce the manual in the future.
Moson
Sorry we currently don’t have manual. And we will produce the manual in the future.
Ed
I have been hearing that for years from ASI. As far back as the ASI120mc years ago. Seems like in seven years you would have gotten to it by now. Also it would be nice to be able to dither from PHD2.
Julian Shull
Today I downloaded ASIStudio from you website and tried to install it on my MACBook, but received an error message saying it would not install for security reasons as it came from an unknown website and directed me to the Apple App Store, which, of course, does not have this. Do you plan on distributing it through the App Store or at least give Apple your credentials so they know you’re not a hacker!
Moson
Yes, we are planning on distributing it through the App Store.
RogerM
left click (or option-click on keyboard) and select “Open” (top of the pop up menu.)
Moson
Sorry I can’t understand, could you please tell us more?
Dennis M
Use the Control- right click key combination to Open anyway – or go to Preferences and allow the Mac to open the software. This is not related to ASI software per se but is the default security setting.
ZWO.Moson
Thank you very much!
Steve
You can open finder, then go to wherever the file you downloaded is stored (usually downloads) and right click then file and choose open, this will then warn you but allow you to run it anyway 🙂
Roberto
Where can I find AsiStudio manuals or docs ?
Thankyou.
Moson
Sorry we currently don’t have ASIStudio manuals or docs. But we will release it as soon as possible.
Aaron
why do you release products without a manual? I can’t even find a manual for the ASIAIR Pro, just the old version. These need to come out with the product for a good user experience.
Moson
We are so sorry for this, the manul of the ASIAIR Pro will be released in the near future.
kippauls
What is ADC tuning for in ASICap?
Moson
The Atmospheric Dispersion Corrector(ADC) is used to reduce the effect of atmospheric dispersion on lunar and planetary images. There is the link for your reference:https://astronomy-imaging-camera.com/product/zwo-adc.
JimmyTwoScoops
Excellent approach to development. Nice to have a piece of software that does not try to be everything to everyone. Please keep up the good work – Great for ZWO sales
Moson
Thanks for supporting us.
John
Just opened ASI studio for the first time on my PC and connected a cooled ZWO camera. I’m wondering how you can determine the current temperature of the sensor so that you know the camera is ready for imaging?
Katherine Tsai
You can see the temp on the top bar of ASIStudio software.
Andrea
I tried ASIlive, but I’ve got Az mount and it looks like to me the images where not aligned correcting field rotation. Does ASIlive corrects for field rotation? if not are you planning to add the feature? Thanks!
Katherine Tsai
Field rotation does not matter when you stacking, the stacking is aligned with stars.
NSKim
Hi everyone,
I have ZWO ASI224MC.
I finished the pre-test check during the day and was capturing the full
moon in the evening when I ran into a problem and got an image.
It’s hard to proceed with the image capture.
A few days ago, I set a ground target for my laptop with the previous
version of ASI Stuido V1.0.1
WIN10, 64bit . The image capture went well and saved as expected.
And the same laptop with ASI224MC to shoot the full door next evening.
I ran ASICap after I ran it, but my laptop only has a black screen and no
moon surface.
I checked the connection configuration with the laptop and ASI224MC
and even double-checked it, but the laptop is still a black screen.
I checked the connectivity between the laptop and ASI224MC, and even
if I touch this and that, the laptop is still on the black screen.
When the camera is separated from the ceiling mirror and facing around,
the screen of the laptop reacts white.
Is it out of focus? I just couldn’t figure out why.
Please let me know the cause and solution.
And yesterday, ASICap screen looks like attached picture, and it doesn’t
go back to full screen.
Touch and run the ASIImg icon next to it to display the full screen immediately.
What is the reason for this? solution method Please let me know.
What changed a few days ago was that the pop-up was upgraded to the
latest version of V1.1.2 (64bit) when ASI Studio ran pop-up.
Thanks,
N.S.Kim
Katherine Tsai
Hi N.S.Kim,
I think we have communicated via emails.;)
nicolas
i just bought a new laptop with 4k screen, and there is no scaling in asistudio, it means icons and texts are almost unreadable. it can be a good idea to have a scaling option to adapt the software to high resolution screen . thanks for this great software
Katherine Tsai
You can find this feature in the setting. Enable high DPI scaling.
Shridhar
Hi Katherine, i have ASIStudio v1.2.1 installed on a mac. I don’t see the high DPI scaling option in settings under any of ASICap, ASIImg or ASILive. Also, other than using the focuser on the telescope, does ASICap provide s/w based focusing options?
ZWO.Moson
You can choose different resolutions under the camera option. Or use the scroll wheel on the mouse to zoom in and out of the image.
You can use our EAF.
David Kolb
The “Save As” feature in the ASIFitsView application is very clunky. It does not allow me to save in folders other than the current folder where the images are saved. Also, the default file name should update as I move between images in the folder and not default to the first image that I opened. The file type drop down should list jpg and png separately and add .png or .jpg automatically so that I don’t have to manually type the extension.
Katherine Tsai
1. Images can be saved to any files on your computers.
2. The filename will be updated.
3. We will add more formats in the future and they will be listed.
4. Could you tell us which version of ASiStudio are you using and what system are you using? You can send us an email to support@zwoptical.com for tech help.

I used ASICap for the first time last night with my ASI178MC imaging Jupiter. It went OK but my AVI was greyscale (B&W). This was in the text file:
[ZWO ASI178MC]

Auto Exp Max Gain = 255
Auto Exp Target Brightness = 100
Bin = 1
Brightness = 10
Capture Area Size = 1920 * 1080

Colour Format = RAW8
Debayer Preview = OFF
Exposure = 158000us
Flip = None
Gain = 1
Hardware Bin = OFF
High Speed Mode = OFF
Mono Bin = OFF
Output Format = *.AVI
Raw Format = ON

StartY = 500
Temperature = 34.7 C
Timestamp Frames = OFF
Turbo USB = 60

Can you tell me what I did wrong?
Katherine Tsai
Please do not check RAW format, then you will get color video.

I am VERY interesting in using the ASI Studio and I am totally loving my ASI2600MC-Pro and 290Mini. How does ASI Studio (installed on a Win 10 laptop) connect to the ASIAIR-Pro? Can it be connected via USB or does it have to be wireless? Is there any estimated time frame for an instruction manual? A lot of the program is very intuitive but an instruction manual is always a good thing. Thanks the support and for creating so many wonderful products.
ZWO.Moson
Thanks for supporting us. But sorry to tell you the ASIStudio is a computer software which is different with the mobile phone app ASIAIR. So they can’t be connected. And we are working on the instruction manual, please wait for a while, thanks.
JAy
Hi,
How can you tell how much time has passed and how much remaining in a running session?
The other question, will ASI live run at the same time with ASIImage, or it replaces ASILive?
Thank you,
ZWO.Moson
You could see the time on the autorun. The ASI live can’t run at the same time with ASIImage.
Dan
Something’s wrong with your last ASIstudio version (1.2.1). I tried to download it, but the file has only 7.5 MB (instead of 30 MB like previous version). When I try to install it, an error appears: file incomplete downloaded. So, please correct the issue.
ZWO.Moson
You can try uninstall the ASIStudio software completely, and then download it again.
Dan
Please fix the download for ASI studio v. 1.2.1 x64. The file is incomplete, it has only 7.5 MB.
ZWO.Moson
Thank you for your feedback, and we will correct the issue.
Ruben
¿Tienen planes de hacer ASIstudio o algún otro programa que se pueda utilizar para EAA en plataformas Android?
ZWO.Moson
You can use ASILive software in ASIStudio. This software is similar with EAA.

Hello friends : This software look fantastic here is my questions
Will ASIStudio be able to pilot

2: My Skywatcher EQ6-R Pro ?
Does it do it now ?
Is it doing it on Mac OS ?
Thank you !
Support@ZWO
Hello
Is it doing it on Mac OS ?
Yes
It is unable to connect&control the AVX or EQ6R directly currently in the ASIstudio
we will convey this requirement to our R&D
Peter Williamson
Hi. Just loaded ASI Studio for my ZWO1600MM Pro.
Using ASIImg for Deep Sky Imaging, can you tell me the actual Gain settings for Low/Middle/High?
Can these Gain settings be changed?
There is no control of Offset. Is this set automatically depending upon Gain setting chosen?
Can it be set manually?
Very impressed so far.
Regards, Peter
Support@ZWO
You do not need to set the gain and offset manually. We recommend keep the default gain and offset,especially for the new users.

I have used an ASI120 camera for planetary imaging. I used ICap 2.4 to capture the images. More recently, I have attempted to use an ASI294 cooled colour camera to take deep sky images. I have downloaded ASIStudio. Although I can use ASICap to take test images of bright objects, I cannot get ASIImg to run. When I click on the ASIImg icon, it just brightens momentarily but then nothing more happens. When I also click on ASILive, I get the same result: the icon brightens for a moment, but nothing else happens.
Any advice on how to get past this step would be greatly appreciated.
Support@ZWO
Have you tried another computer with the same result?

Hello,
I am new to astrophotography and the ASIStudio suite and very easy to learn. Well done to the developer for their work. And it is possible to inculcate a feature that allows you to clear the sky of all clouds at night 😉
Good luck to the ZWO team

Are your programmers continuing their development of this ambitious software suite? The early announcement sounded very promising, but there seems to be few advancements since then.
Thank you for what you’ve done so far!

Hello,
I own several ASI products, all controlled via ASIAIR. Would the studio software somehow link up with the ASIAIR or will this only work with the tablet? I would like to use studio, but wirelessly from the comfort of inside the house. That is why I got the ASIAIR… but running the controlling software on a desktop seems more convenient. Thanks!
sara.liu
The ASIStudio can be run via desktop, it can not be controlled via ASIAIR.
Reinhard
Hi ASI folks,
I am using a ASI183MM Pro camera and wanted to shoot Darks today through ASIIMG on my Mac laptop. However I cannot set the gain to the exact vale (111) at which I shot my Lights. The only setting options for the camera gain ASIIMG gives me are „Low“, „Medium“ and „High“. Am I missing something? Or have you just not yet implemented precise gain settings in ASIIMG? In that case it would be very useful to add this feature.
For my imaging sessions I am using an ASIAIR Pro, which allows for precise setting of the gain value.
Best regards,
Reinhard
sara.liu
ASIImg currently can only set three levels of “low”, “medium” and “high”, because for DSO, it is enough. But for the further needs, we will optimize the software, after the gain will add a custom feature that allows the users to set the specific value. In the current situation, we recommend you to use ASICap to shoot, the ASICap can set any gain.
Frank D
WOW, this article really needs to be redone.. that pic shows only 3 icons? the newest version as of this week for ME, is Much better with more options , like 5 now .. Planetary Imaging, Deep Sky Imaging, Live Stacking, Fits Voewer and Deek Sky Stacking .. are all the options available a year later.. I Hope they rewrite this article and leave a link to it from this one…
