Hi misho,
I don't think there is any filter in particular to block out the stars, the contents of the frame are simply so bright compared to the stars that they do not show up. This is the same reason there are no stars visible in (most of) the moon landing photos - the lunar surface reflected too much light.
I suppose there would be a filter, just a high light level filter like a pair of sunglasses (notice the space suit faceplate is tinted dark also), but nothing fancy.
