I agree with the comments, it doesn't look military in nature. Looking at various organization, I finally found an item listed on ebay which seems to match both the wide emblem and the tasseled 8-point star with cross inset.
I've zoomed in on part of the image showing the large emblem on the sash, revealing the motto Amicitia Amor et Veritas or in English: "Friendship, Love and Truth". So it appears your ancestor was an Odd Fellow (no insult intended).
