Stacking older Seestar data again does not work

Starkissing

I tried to put some data I saved on an external drive back to the Seestar via PC. Unfortuntely, Seestar does not seem to see them any more.

Example: I image M51. I get 2 directories in "MyWorks": "M 51" and "M 51-sub". I move them to n external drive with a PC to get space on the Seestar's memory. A few weeks later, I copy the directories back from the external drive to the empty Seestar's "MyWorks" folder. When I try to re-stack them, the app jut tells me "No deep sky images yet".

What am I missing? I want to use the new denoise on my old data.

I think the S50 use a local database for the files. Have observed the same thing. I now the data is there but the app doesn't find it.

So better not move the data to an external drive until you really need the space... Except you never use internal stacking.

It can only read the folder which named with sub.
