I turned my Seestar preprocessing SSF scripts into a python script that gives you more control and also lets you process Dwarf and Celestron origin images. Note: Origin images are currently not working, I'm looking into it. 

 

 

Here's a demo video on how this works: https://www.youtube....h?v=E_LIjdVQdSg

 

You can download the script here: https://github.com/n...t/siril-scripts

 

Python in Siril is still in beta so there are some workarounds I do in my code but so far it works really well. The video goes over some troubleshooting steps but if anyone tries and runs into issues, let me know. 

 

Future work includes adding calibration frames and more smart scopes to the list (and a better user interface).

Could you point me to some documentation on setting up Python with Seril 1.4? I get a very general error message on start up and I'm out of ideas. I'm on Windows.

What error are you getting? One thing you can try is go to Scripts >> Python Scripts >> Siril_Catalog_installer.py. Running this script and installing the astrometry/spcc data fixes python issues. 

 

If that doesn't help, if you can send me a screenshot, I can take a look.

After installing 1.4 and seeing Python fail I did a standard Python installation but it did not help. (Possible pathing issue?)

On startup I get this:

Any help appreciated. (I'm a little embarrassed to admit I was a UNIX/Linux admin for 20+ years, but sometimes Windows stumps me.)

Go to the Siril's preferences: scripts tab.
At the very bottom (scroll if needed) click on "reset Python Venv"

would love to see Vaonis Scopes added to this script. used to use siril to stack a bunch of my Vespera Images.

Adding to what Cyril said about resetting venv, I'd ask you to double check that "C:\Program Files\Siril\python\python.exe" actually exists. Python is bundled with Siril so you shouldn't need anything extra. This is just to make sure it's installed in the expected location.

 

And nothing to be embarrassed about! I work with both Linux and Windows and I mix them up all the time, especially when I'm doing things in command line.

[lsjones]

Thank you both for your help. That did not solve the issue, is this forum the proper venue to troubleshoot this?

 

I see that C:\Program Files\Siril\python does not exist. 

 

>where python, returns:

C:\Users\lsjon\AppData\Local\Microsoft\WindowsApps\python.exe
C:\Users\lsjon\AppData\Local\Programs\Python\Python313\python.exe

 

>python --version, returns:

Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Apps > Advanced app settings > App execution aliases.

 

The preferences Scripts page has script locations as:

C:\Users\lsjon\AppData\Roaming\siril\scripts
C:\Program Files\Siril\scripts

 

My full PATH is a crime against humanity but does contain:

;C:\Users\lsjon\AppData\Local\Programs\Python\Python313\Scripts\;C:\Users\lsjon\AppData\Local\Programs\Python\Python313\;C:\Users\lsjon\AppData\Local\Programs\Python\Launcher\

If python does not exist please be sure to download the beta 2 version and to reinstall it.

[lsjones]

That was my next move. 

 

(ETA Predictably enough that seems to have solved the problem. Thanks for the help!

I’ve been using your previous Siril 1.4 preprocessing scripts and it works well. Nice to see it in python form now. 
 

Curious what success people have had with drizzle above 1.0 on the Seestar and what settings were used. I tried a 2x but it created some odd noise patterns that looked like multicolored stars (and noise reduction would ignore it, thinking it’s data). Perhaps it’s the pixel fraction that needs to change? Haven’t experimented much with that yet. 

[Silent_Light]

No idea if you can help....but I've noticed that the Seti Astro python scripts in beta 1.4 2 shut off my PC when they finish. Nothing has ever crashed my computer till now. Win 11 pro.

Is there something about the scripts that do that ? I'm no programmer and don't intend to be

I tested 2x and 3x drizzle and I've seen some odd noise patterns but nothing bad enough that raised alarms. How many frames are you stacking? You'd normally need a lot of images for drizzle to be effective. I usually just stick with 1x drizzle. 

 

Siril recommends an inverse change for pixel fraction So if you do 2x drizzle, you're supposed to do 0.5px. I've experimented a bit with different values but haven't done an in-depth analysis yet.

It shuts your pc off? That is strange! I wonder if it's your GPU getting overwhelmed. Can you uncheck "use GPU" and see if that helps?

It sure does ! With an 8gb GPU and 8 core pc processor I've never had any issues with graphics or stacking huge imaging data sets (imx571) once. Gaming on ultra mode has been seamless.

I'll have to figure out where "use gpu" even is.....

Has to be something in the script itself.

I'm looking at the Cosmic Clarity Sharpening and Denoise script, 'Use GPU' is a checkbox right in the UI. 

 

These are the only two I've used of his so far. 

 

It may not be the GPU setting but I can't think of anything else that could cause your pc to crash. Maybe a RAM card getting some kind of error?

To use drizzlex2/ drop 0.9 / Square as per tradition Pixinsight…I shoot at least 6 hours in bortle 8 to 9. Lower than that for me it’s just loss of SNR that doesn’t compensate gain in resolution.

 

The gain in non stellar objects is only visible after deconvolution in graxpert or BlurX and you need thick signal.

grabbed a handful of subs to test

selected key options in the panel and hit run / seems to stack all the images fine but i got this error pop up with a bunch of red text  >>> here is the log thats in red >>>>

i know absolutley nothing about scripting coding or any of that stuff sry   ALSO i noticed after i run the script if i want to run it it again i have to reset the working directory everytime , i did reset python  in the preferences several times

Airstrike, sorry, I didn't see your response earlier. I would have sent you a link to try the beta version of the script. 

 

The newest version of this script is officially part of Siril's script repository so it's easier to install and comes with a few enhancements and bug fixes. 

 

Watch the full demo here: https://www.youtube....h?v=HVHnaRuaLDk

 

 

 

 

Give this a shot and let me know if that works better for you. 

 

[kabes]

I was able to improve my 2x drizzle results by switching the kernel from square to gaussian by manually editing the script file. No more weird fake stars in the background (they were only visible after denoising). Maybe something to consider adding as an option. I plan to experiment with lanczos2 and lanczos3 next.

That's great to know, thank you! I plan on creating a few 'advanced options' available for people. A few advanced users have suggested it so I might do that for the next patch in a couple of weeks. 

 

Let me know what you find with your experiment with lanczos2 and lanczos3!

Thank you!

I was just trying lanczos2 and lanczos3 but both of them cause the script to fail at stacking near the end when it's doing the normalization (after it's done scanning for black frames). This is with S50 data. Back to gaussian and it's still fine.

Interesting, thank you. I'm away from home until Wednesday, I'll do some testing when I get home as well.

Quite often, the python script fails after producing the OG image and doesn't proceed to create the SPCC images or others? I'm using the seestar s50 and latest Siril. Any ideas? The final error Siril displays is "Load command failed: Command 'load' failed: File not found. The errors start happening after this log, "M_27_773x20sec_2025-06-01_drizzle-2.0x__2025-06-19_0957_og.fits: file not found or not supported." This happens although the file has been created and is accessible in the folder.

Can you share your logs? I can take a look.
