Future new astrophotographer (I'll STILL take plane pics, though)

I just got a Bahtinov mask and then found out I have to buy a new cheap filter to use it on (on it's way now - didn't want to use a $16 mask on a brand new $55 UV filter I ordered at the same time!). The mask has a shiny bumpy side and a flat matte side. Does it matter which side goes into the filter? I'll be using it on my 70-200 G2 f/2.8 (Sony) lens.
