Oh it also automatically stitches mosaics (if coordinates info exists in the headers). And I'll be making it work with dual narrowband and broadband data at the same time in the next release. First version will be just the basics.

Ah okay, thanks. I use APP for stacking and mosaics. Up to now I've found Siril hard work for most things but I'll keep trying! I particularly dislike the way it flips images for no apparent reason!

Siril does not flip images. It reads and writes data in the right orientation, like professional software. Contrary to APP reading and writing images top-down, and same for a lot of capture software.

Thanks. This is interesting. In technical arenas, inconsistent use of standards has often created problems for users and consumers. Sadly, I think its true to say that the 'best' approach has not always been the one that becomes adopted as the standard! Video and HDTV back in the day are examples

I have definitely had occasions where image orientation is different to the orientation I see on the sky. All other software I use (APP, Affinity, Photoshop) maintains the same orientation throughout processing. I read online its to do with header data. Regardless, sadly it happens

Yes. Sadly because capture software (and APP) does not respect standards (Same for PI but you can change the default behavior). However, some capture software respect that, like CCDciel

Thanks for the reply. I'm not sure what standards you refer to. From memory it appeared image dependant and therefore inconsistent. When using several apps in my workflow I'm afraid I found this awkward and frustrating. I still use Siril for some steps though

I need to make some UI improvements based on what APP does (e.g. assign frames to multiple sessions, naming sessions, etc.)

Sounds good 👍

I took some inspiration from being a longtime APP user myself! Mosaics in Siril is new and one benefit it has over APP right now is the ability to plate solve individual images. Makes stitching mosaics MUCH easier because you can register based on coordinates instead of relying on star patterns.

Thats interesting. APP gets very high praise for its star registration capabilities, and hence mosaicing. Would be interesting to see data that demonstrates Siril is 'superior'

I don't know if I'd call it superior since it's still in beta but using plate solved data instead of only star alignment, you don't even need to overlap your frames to create a mosaic. This is a rough example of stacking 3 frames for each the Heart and Soul Nebula.

Nice 👌
