Help with a common scenario and for updating a tutorial

[prusling]

Hi, I am a long-term user of Sirilic for OSC and narrowband pre-processing and an advocate for its ease of use.  Some time ago I put together a tutorial in English which is now in need of updating.

As Siril has included more functionality, Sirilic has kept pace with its Properties tab and I feel it would now be useful to update the Sirilic tutorial with various common use cases.

As an example, I currently wish to pre-process two OSC sessions of the same target, one using a broadband filter and the other using a duoband filter. I am happy to post-process these using my preferred tool so what I am seeking are two separate stacks (one for each session) which are registered/aligned with each other.  I'm not sure what combination of multi-session / registration / plate-solving is now needed?

Please can someone advise the best way to do this, and also suggest what other common use cases could be covered in an updated tutorial.

Many thanks in anticipation, and to m27trognondepomme for all his work on this excellent tool.
