Have been reviewing saved auto focus packages (don’t ask 
!). There is no way to tell which filter was used for the focus run. Perhaps moot for those that are using filter offsets (and therefore always same filter). For various reasons, I am not there currently.
Could the filter name be added to the autofocus graph and/or the filename and/or the folder name and/or the FITS header?
Cheers,

PS. What do the numbers in the Auto Focus Package folder name represent?
