Stack anything and Everything with my Siril OSC PP Script – v2.0.3 is now in Open Beta!

By Naztronomy • Posted on 5/1/2026

Please download the script here: https://github.com/naztronaut/siril-scripts/blob/osc_pp_v2.0.3_dragondrop/Naztronomy-OSC_PP.py

There are some big UI changes to this, mostly “Drag n’ Drop” functionality which tries to automatically place subs where they belong. This is in open beta so you do need to install it manually. I’m doing it this way because I don’t want to override the current version in production which is very stable.

Notable release notes:

  • Drag and drop files and folders
    • Get prompted for file type (e.g. lights, darks, flats, biases, and master frames)
    • Get prompted to add calibration frames to multiple sessions
    • Dragging parent directories with multiple inner directories will auto create sessions
  • Handling of dark flats
  • Better tooltips
  • Fixed bug where non-Fits files were not working – you can now stack Canon and Nikon (and other) images if you need. Note that these will not properly mosaic!
  • Tip: For multi panel stacking, try 200px feather, that seems to work well for everyone.

I’m also heading to Montreal for a about a week so responses may be slow. Another reason why I didn’t want to push this out publicly and possibly break things on a working script.

As always, thank you all for your support and any feedback you provide.
