Without doubt the Baader Solar Film showed a higher resolution.
I observed with the Baader Film for half an hour.
I isolated a sunspot that had 2 large components and a 3rd very small component.
When I swapped to the glass filter I could not see this 3rd very small component at all.
However the film is very flimsy and it would be easy not to notice a fresh tear or pinholes.
The glass seems safer to me - but losing resolution is not acceptable.
