For a long period of time, astrophotographers have to face the dilemma between spending a long time flattening the steep learning curve of astrophotography and just giving up to let go. The software too complicated to start with, the tedious imaging settings and post processing and so many other problems are what astrophotographers deal with each time when they are involved in a new astrophotography project.

Yet all the processes can get simplified by ASIAIR. You may know ASIAIR as a good image tool before – it can do polar alignment, plate solve, focusing, autoguiding, GOTO, autorun and other features with ease. However, ASIAIR can actually do much more than above now. With the new version 2.0, you can stack your planetary and deep-sky targets and quickly process them on your phone – bye bye laptop!

Here we’d like to introduce you how to use the stack function of ASIAIR.

As always, connect your phone to the ASIAIR WiFi and then launch the ASIAIR APP. If you take a closer look, you’ll notice that the v2.0 interface has changed a lot. The UI design and layout have been easier for users to understand and much more friendly for night work.

ASIAIR 2.0 Interface

Go [File Manager], you may see [DSO Stacking] and [Planetary Stacking] on this page. Let’s talk about the DSO Stacking first. This feature is different from the live stack that we used to know. Live stack is for you to stack the DSO data while capturing, while the DSO Stacking here is for you to stack and simply process the data after you complete the data acquisition.

File Manager – ASIAIR

Choose the files you’re going to stack. The stacking process will be automatically done once you click [Done].

Choose the DSO target to stack

You will see how many frames were stacked successfully and how many are failed from the pop-up window.

The stacked fits files can be viewed, shared as a JPG to the ASIAIR community, and also edited if you want to further improve the image quality.

The adjustable options include histogram, brightness, contrast, saturation and Bin mode.

You can also crop the image or mirror, rotate it as you wish.

The whole stacking and processing progress is very quick and easy. Of course, if you want to do some more advanced post-processing work for your image, you may still choose Photoshop or PixInsight, but ASIAIR offers a much easier choice for all astronomy amateurs, especially the new beginners. You can produce a good enough astrophoto in minutes, instead of sitting before the computer for hours with a deep frown on your face.

Below is the NGC6992 before and after stack.

Apart from DSO stacking, ASIAIR can also do planetary stacking. You can stack and sharpen the Sun, our Moon and the planets in the solar system. To help you get a better solar or lunar image with clear details, ASIAIR allows you to choose the alignment point before stack. And for solar stacking, ASIAIR also supports colorization for mono image and color invert.

Basically, the stacking process for planetary videos is similar to DSO stacking. One of the few differences is that the histogram can only be viewed but not stretched in edit.

Choose the video you’re going to stack.

Share it to the community or save the image.

Really simple, right? With the new 2.0 version of ASIAIR, you now can complete the whole capture and process workflow on your phone. Astrophotography can be fun for every amateur, no matter you are a master or just a newbie.

    Hi AsiAir team,

    I am using ASIAir Plus and ASIAir V .

    But Video stacking option is not available whenever I am opening the video file from Image Management.
    Could you please assist. Also Guide RA/Dec graph is not showing up the graphical changes.

    Comment *where’s the stacking option?

    I’ve been trying to stack some luna videos avi files, but there’s no stacking option… what am I doing wrong?

    Comment your software is sadly lacking documentation on how to proceed step by step. It is predominantly all Astro and not Solar. I only recently learned to turn off the AUTO histogram in order to see the full disk of the sun. No manual or work flow process on how to proceed. There is a special “Solar Fuction” that talks about what it can do and nothing about exactly how to do it. Running into a lot of speed bumps related to one setting canceling another. For example…GOTO is canceled when CENTER TARGET is selected. No warning or conflict post listed anywhere.

    Also, in Solar we are in bright daylight. I suggest your software designer try using their app in bright light and find the gray slider bars buried in the screen glare. Better yet, publish a detail tutorial on this feature.

    Unable to focus well compared to ShareCap with it’s 200% or more zoom on live video. Can’t focus what I can’t see.

    I welcome your advice, references, or links to said items above.

    I have 58 light images of M31, 10 Dark, 10 Bias, and 10 Flats. All stacked. Nowhere on my iPad do I see any way to get an image?
    My DSO does not show any of the processing in the above. I have the ASIair Plus. In Image management, all I see are the files. The only options I see are to stack files again or delete them.
    Any help would be appreciated.

    So. It does not include dark, flat, and dark fats?

    This is such a great feature…I use it all the time with great results.

    For some reason , when doing Lunar stacking, at the alignment step, the sample image does not appear….any suggestions?

    Not for mono LRGB/SHO imaging, I suppose?

    So, The Entire Stacking Process Takes Places In ASIAir Or The Photos Get Transferred To Phone/Tablet First & Then Uses The Computational Power To Stack Those Images? Or Is It All Been Done On The Air Itself?
