Black borders in integration result using the Reference composition mode  

Thanks for notifying, do you have a screenshot of what exactly you mean? I can't actually see this black border for instance in the above comet integrations.

@vincent-mod Ahhh... sorry Vincent, it was a completely misunderstanding - please don't care about it, because I mean for black collums on my photo, not borders! But maybe it was a calibration error from my fault, I don't know. If it's not problem, I delete my previous comment and please care about Rodolphe Goldsztejn's commet!

No worries. 🙂

Hello @vincent-mod

See attachments.

Direct outputs from APP, loaded and stretched in PixInsight.

Hope this shows clearly in the screenshots.

If FITS needed, I will share from OneDrive - they are too large for attaching.

Thanks

This does look like you had slightly different field of views (very tiny rotation) and APP stacked them with this in mind? Would you be able to try this on a dataset that you know doesn't have this?

Hi,

makes sense indeed. Will check with other data sets but not sure I can find one with absolute 0 rotation.

Anyways, this is really not a critical issue, I can live with it as solutions are trivial to fix it.

Thanks!
