DSS to ASTAP file format conversion.

[MalcolmP]

Converting my archive of DSLR stacked (in DSS) TIF images to a FTS image that ASTAP will accept.
When I open the tif in DSS I have a choice of 3 fts save options
1) 16bit/ch
2) 32bit/ch - rational
3) 32bit/ch - integer

Astap accepts all (and I can then plate solve and organize my archive), but which of the three  would be best to use/keep ?

thanks.

Why not use Siril? Can take multiple images in one take. Learn to use the "Convert" tab.
