ALS - Astro Live Stacker

Hi
Dragonlost and i are very proud to introduce our little toy "ALS" / Astro Live Stacker.
It's a small Python(3) application dedicated to live stack.


It's watching a specified folder for new FITS frames to arrive.
Each new frame is stacked with previous result.
Two methods are available : sum and mean.
It can also register on the fly.
If Bayer pattern is present in fits header, demosaic is also done on the fly.
You can use it with eKos sequence, telling ALS where FITS files are stored.
But you can use any other software providing FITS frames.

We will try to add a dark substraction,
and will add this interesting request from one of us :
Opening a webserver to publish stacked image.
Why ?
During a public session, people could connect to our local hotspot and see and download "their" image

I've done a video to show it working, it's in french but you'll see it running with a CCD simulator and real archived frames


It's really an early beta -but working- toy
Any ideas and improvments are wellcomed, feel free to involve :
github.com/gehelem/als

This is the place for me to thank Dragonlost for his tremedous help

Gilles.

Hi Gilles, Dragonlost,

I tried ALS. Good job.
It needs some work but I think you are nearly there.

I'd be happy to test new releases and give feedback.

Cheers,

Marco

Great work. I look forward to using this at public star parties I volunteer at.
Are the debayered images correcting for the RGGB green bias? If not it won't be as well received in public sessions.

Thank you for your feedback
Dragonlost is trying to add level correction atm

Hi Gilles, Dragonlost,

thank-you for sharing on github, nice work!
master branch runs perfectly on ubuntu 18.10.
With beta branch I'm getting errors when I click Play and for alpha branch
I'm not seeing any stack image: the log feed cycles only on two images seemingly:
Read New image ...
Read First image ...
Happy to be a tester if you want one. I'm keen to try this on my rpi 3b+ .

best regards,
Dean

With public outreach in mind, it might be a good idea to generate a QR code for people to access a the stacked images over the proposed hotspot access point along with some fields to enter file name tags for What, Where and When.

excellent feature. looking forward to trying it out.

Hi

A new version is out
https://github.com/gehelem/als


Deufrai has completely taken over the project, his immense contribution has allowed us to structure and make it more reliable.
New features, stability, new UI, better gihub structuration
and finaly a new web site :
als-app.org/index.html



Happy testing !!

Gilles.

Nice software, simplicity and efficiency.

Some try... with canon 450D, 20 secondes on 80ED (old files)

Hi,

How are we going to create a menu shortcut or desktop shortcut for als?

Thanks
