Live stack looping on first file ?

[geert declercq]

Hello,
first of all thanks for all the effort you're putting into ASTAP!
I'm running ASTAP on a MacBook M1.

• Created a master dark from 30 exposures, dark list only contains a reference to the master dark file
• Created a master flat from 30 exposures, flat list only contains a reference to the master flat file
• Start live stack on empty folder
• Put one raw file (cr2) into the folder
  Result:

It looks to me that it's constantly processing the first file, also it reports that it's using 30 darks and 30 flats; am I doing something wrong or am I misunderstanding something?

Thanks for clarifying!

Yes something weird is happening, restacking a single file. I have to check that after mid october when I'm back home. The live stack routine was modified some time ago where new file detecting is noe based on file date and not on renaming. converting cr2 to fits could the cause.

reporting 30 dark, flata is normal. This because they are master dark/flats representing these amounts.

Note that flat-dark/bias are missing. You have to recreate the master flat again from original files.there is no master bias. it is included in the master flat.

For the moment you probably avoid it by jpeg or tiff files if you can set that in the camera. But results will be poor compared with raw.

Hello Han,

thanks for clarifying; there's no hurry, take your time to fix it.

This is now fixed in the code. Reason was that files names internally get a .fits extension if loaded from .cr2. I will upload a Mac version today or tomorrow.

New version is uploaded.

In version 2022-10-22 it will automatically detect if it is a raw colour image or a monochrome image.
