Hi Knox,

astropy.io.fits has a function `table_to_hdu` which may make things easier for you.
Here's an example:

from astropy.io.fits import table_to_hdu, HDUList, PrimaryHDU
from astropy.table import Table

HDUList([
   PrimaryHDU(),
   table_to_hdu( Table({'a': [1,2]})),
   table_to_hdu( Table({'b': [1,2,3]}))
]).writeto('test.fits')

(possibly appending to a HDU list inside a loop in your case.)
